New FreeBSD development branch installation ISOs and virtual machine
disk images have been uploaded to the FTP mirrors.
Subversion logs since the last set of snapshots attached to this
email.
As with any development branch, the installation snapshots are not
intended for use on production systems. We do, however, encourage
testing on non-production systems as much as possible.
Important note: non-x86 snapshots are generated in a cross-build
environment, not natively built on their respective architectures.
Checksums for the installation ISOs and the VM disk images follow at
the end of this email.
=== Installation ISOs ===
bootonly.iso, disc1.iso, and memstick.img images are available for:
o 10.0-CURRENT amd64
o 10.0-CURRENT i386
o 10.0-CURRENT ia64
o 10.0-CURRENT powerpc
o 10.0-CURRENT powepc64
o 10.0-CURRENT sparc64
Snapshots may be downloaded from the corresponding architecture
directory from:
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/
Please be patient if your local FTP mirror has not yet caught
up with the changes.
Problems, bug reports, or regression reports should be reported
through the GNATS PR system or the appropriate mailing list, such
as -current@ or -stable@ .
=== Virtual Machine Disk Images ===
VM disk images are available for the following FreeBSD branches for
the amd64 and i386 architectures:
o 10.0-CURRENT amd64
o 10.0-CURRENT i386
Disk images may be downloaded from the following URL (or any of the
FreeBSD FTP mirrors):
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/VM-IMAGES/Latest/
Images are available in the following disk image formats:
- QCOW2
- VMDK
The partition layout is:
- 512k - freebsd-boot GPT partition type (bootfs GPT label)
- 1GB - freebsd-swap GPT partition type (swapfs GPT label)
- ~8GB - freebsd-ufs GPT partition type (rootfs UFS label)

When code from r254064 in pmap_ts_referenced() drops pv lock and
blocks on a pmap lock, pmap_release() might proceed in parallel and
destroy the pmap mutex, since unlocked pv lock allows to remove pv
entry owned by the pmap.
For now, gate the pmap_release() on write-locked pvh_global_lock.
Since pmap_ts_release() does not unlock the global lock,
pmap_release() would not destroy pmap mutex until the
pmap_ts_referenced() finished. We cannot enter pmap_ts_referenced()
and encounter a pv entry for the destroyed pmap if pmap_release()
passed the global lock gate, since pmap_remove_pages() would finish
earlier.

Allow a hardware driver to pass clock frequencies into the sdhci driver.
The sdhci spec says that if the base or timeout clock frequency in the
capabilities register is zero, the driver must obtain the frequency "from
another source." This change defines that other source to be the low-level
hardware driver, which can pre-set the frequencies in slot.max_clk and
slot.timeout_clk before calling sdhci_init_slot().
This helps with a growing number of SoCs that have sdhci base clock
frequencies that either won't fit into the range allowed by the number of
bits available in the capabilities register, or the frequency is runtime-
configurable.

Simplify pv_entry removal or ARMv6/v7:
- PGA_WRITEABLE indicates that there *might be* a writable mapping for the
particular page, so to avoid frequent sweeping of the pv_entries whenever
pmap_nuke_pv(), pmap_modify_pv(), etc. is called, it is sufficient to
clear that flag if there are no managed mappings for that page anymore
(notice that only pmap_enter is authorized to set this flag).
- Avoid redundant checking for PVF_WIRED flag when this flag cannot be set
anyway.
- Clear PGA_WRITEABLE only once for each vm_page instead of multiple,
redundant clearing it in loop when there are no writeable mappings
to that page anymore.

Revise L2_S_PROT_MASK to include all of the protection bits. Notice that

cleared but are to be set or left cleared accordingly in pmap_set_prot(),
pmap_enter_locked(), etc.
Clear L2_XN along with L2_S_PROT_MASK in pmap_set_prot() so that all
permissions related bits are cleared before actual configuration.

Simplify and clean up pmap_clearbit()
There is no need for calling vm_page_dirty() when clearing "modified" flag as
it is already set for that page in pmap_fault_fixup() or pmap_enter() thanks
to "modified" bit emulation.
Also, there is no need for checking PTE "referenced" or "writeable" flags. If
there is a request to clear a particular flag we should just do it.

the expense of potential failures when the backend can't supply enough

Make the standard sdhci(4) driver work for the TI OMAP family SoCs.
The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.
This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.
This initial incarnation lacks DMA support (coming soon). Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.

Enhance the ZFS vdev layer to maintain both a logical and a physical
minimum allocation size for devices. Use this information to
automatically increase ZFS's minimum allocation size for new top-level
vdevs to a value that more closely matches the optimum device
allocation size.
Use GEOM's stripesize attribute, if set, as the physical sector
size of the GEOM.
Calculate the minimum blocksize of each metaslab class. Use the
calculated value instead of SPA_MINBLOCKSIZE (512b) when determining
the likelyhood of compression yeilding a reduction in physical space
usage.
Report devices with sub-optimal block size configuration in "zpool
status". Also properly fail attempts to attach devices with a
logical block size greater than 8kB, since this will cause corruption
to ZFS's label area.

MFC after: 2 weeks
Background
==========
Many modern devices use physical allocation units that are much
larger than the minimum logical allocation size accessible by
external commands. Two prevalent examples of this are 512e disk
drives (512b logical sector, 4K physical sector) and flash devices
(512b logical sector, 4K or larger allocation block size, and 128k
or larger erase block size). Operations that modify less than the
physical sector size result in a costly read-modify-write or garbage
collection sequence on these devices.
Simply exporting the true physical sector of the device to ZFS would
yield optimal performance, but has two serious drawbacks:
1) Existing pools created with devices that have different logical
and physical block sizes, but were configured to use the logical
block size (e.g. because the OS version used for pool construction
reported the logical block size instead of the physical block
size) will suddenly find that the vdev allocation size has
increased. This can be easily tolerated for active members of
the array, but ZFS would prevent replacement of a vdev with
another identical device because it now appears that the smaller
allocation size required by the pool is not supported by the new
device.
2) The device's physical block size may be too large to be supported
by ZFS. The optimal allocation size for the vdev may be quite
large. For example, a RAID controller may export a vdev that
requires read-modify-write cycles unless accessed using 64k
aligned/sized requests. ZFS currently has an 8k minimum block
size limit.
Reporting both the logical and physical allocation sizes for vdevs
solves these problems. A device may be used so long as the logical
block size is compatible with the configuration. By comparing the
logical and physical block sizes, new configurations can be optimized
and administrators can be notified of any existing pools that are
sub-optimal.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/spa.h:
Add the SPA_ASHIFT constant. ZFS currently has a hard upper
limit of 13 (8k) for ashift and this constant is used to
both document and enforce this limit.
sys/cddl/contrib/opensolaris/uts/common/sys/fs/zfs.h:
Add the VDEV_AUX_ASHIFT_TOO_BIG error code.
Add fields for exporting the configured, logical, and
physical ashift to the vdev_stat_t structure.
Add VDEV_STAT_VALID() macro which can be used to verify the
presence of required vdev_stat_t fields in nvlist data.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c:
Provide a SYSCTL_PROC handler for "max_auto_ashift". Since
the limit is only referenced long after boot when a create
operation occurs, there's no compelling need for it to be
a boot time configurable tunable. This also allows the
validation code for the max_auto_ashift value to be contained
within the sysctl handler.
Populate the new fields in the vdev_stat_t structure.
Fail vdev opens if the vdev reports an ashift larger than
SPA_MAXASHIFT.
Propogate vdev_logical_ashift and vdev_physical_ashift between
child and parent vdevs as is done for vdev_ashift.
In vdev_open(), restore code that fails opens for devices
where vdev_ashift grows. This can only happen now if the
device's logical ashift grows, which means it really isn't
safe to use the device.

didn't show up in the non-error case, because the status was reset
to something valid (e.g. CAM_REQ_CMP) later on in the function.
But in the error case, such as when the driver ran out of chain
frames, the CAM_REQUEUE_REQ status was ORed in to the bogus status
value. This led to the CAM transport layer repeatedly releasing
the SIM queue, because it though that the CAM_RELEASE_SIMQ flag had
been set. The symptom was messages like this on the console when
INVARIANTS were enabled:
xpt_release_simq: requested 1 > present 0
xpt_release_simq: requested 1 > present 0
xpt_release_simq: requested 1 > present 0
mps_sas.c: In mpssas_scsiio_complete(), use &= to take status
bits out. |= adds them in.
In the error case in mpssas_scsiio_complete(), set
the status to CAM_REQUEUE_REQ, don't OR it in.

Expand the use of stat(2) flags to allow storing some Windows/DOS
and CIFS file attributes as BSD stat(2) flags.
This work is intended to be compatible with ZFS, the Solaris CIFS
server's interaction with ZFS, somewhat compatible with MacOS X,
and of course compatible with Windows.
The Windows attributes that are implemented were chosen based on
the attributes that ZFS already supports.
The summary of the flags is as follows:
UF_SYSTEM: Command line name: "system" or "usystem"
ZFS name: XAT_SYSTEM, ZFS_SYSTEM
Windows: FILE_ATTRIBUTE_SYSTEM
This flag means that the file is used by the
operating system. FreeBSD does not enforce any
special handling when this flag is set.
UF_SPARSE: Command line name: "sparse" or "usparse"
ZFS name: XAT_SPARSE, ZFS_SPARSE
Windows: FILE_ATTRIBUTE_SPARSE_FILE
This flag means that the file is sparse. Although
ZFS may modify this in some situations, there is
not generally any special handling for this flag.
UF_OFFLINE: Command line name: "offline" or "uoffline"
ZFS name: XAT_OFFLINE, ZFS_OFFLINE
Windows: FILE_ATTRIBUTE_OFFLINE
This flag means that the file has been moved to
offline storage. FreeBSD does not have any special
handling for this flag.
UF_REPARSE: Command line name: "reparse" or "ureparse"
ZFS name: XAT_REPARSE, ZFS_REPARSE
Windows: FILE_ATTRIBUTE_REPARSE_POINT
This flag means that the file is a Windows reparse
point. ZFS has special handling code for reparse
points, but we don't currently have the other
supporting infrastructure for them.
UF_HIDDEN: Command line name: "hidden" or "uhidden"
ZFS name: XAT_HIDDEN, ZFS_HIDDEN
Windows: FILE_ATTRIBUTE_HIDDEN
This flag means that the file may be excluded from
a directory listing if the application honors it.
FreeBSD has no special handling for this flag.
The name and bit definition for UF_HIDDEN are
identical to the definition in MacOS X.
UF_READONLY: Command line name: "urdonly", "rdonly", "readonly"
ZFS name: XAT_READONLY, ZFS_READONLY
Windows: FILE_ATTRIBUTE_READONLY
This flag means that the file may not written or
appended, but its attributes may be changed.
ZFS currently enforces this flag, but Illumos
developers have discussed disabling enforcement.
The behavior of this flag is different than MacOS X.
MacOS X uses UF_IMMUTABLE to represent the DOS
readonly permission, but that flag has a stronger
meaning than the semantics of DOS readonly permissions.
UF_ARCHIVE: Command line name: "uarch", "uarchive"
ZFS_NAME: XAT_ARCHIVE, ZFS_ARCHIVE
Windows name: FILE_ATTRIBUTE_ARCHIVE
The UF_ARCHIVED flag means that the file has changed and
needs to be archived. The meaning is same as
the Windows FILE_ATTRIBUTE_ARCHIVE attribute, and
the ZFS XAT_ARCHIVE and ZFS_ARCHIVE attribute.
msdosfs and ZFS have special handling for this flag.
i.e. they will set it when the file changes.
sys/param.h: Bump __FreeBSD_version to 1000047 for the
addition of new stat(2) flags.
chflags.1: Document the new command line flag names
(e.g. "system", "hidden") available to the
user.
ls.1: Reference chflags(1) for a list of file flags
and their meanings.
strtofflags.c: Implement the mapping between the new
command line flag names and new stat(2)
flags.
chflags.2: Document all of the new stat(2) flags, and
explain the intended behavior in a little
more detail. Explain how they map to
Windows file attributes.
Different filesystems behave differently
with respect to flags, so warn the
application developer to take care when
using them.
zfs_vnops.c: Add support for getting and setting the
UF_ARCHIVE, UF_READONLY, UF_SYSTEM, UF_HIDDEN,
UF_REPARSE, UF_OFFLINE, and UF_SPARSE flags.
All of these flags are implemented using
attributes that ZFS already supports, so
the on-disk format has not changed.
ZFS currently doesn't allow setting the
UF_REPARSE flag, and we don't really have
the other infrastructure to support reparse
points.
msdosfs_denode.c,
msdosfs_vnops.c: Add support for getting and setting
UF_HIDDEN, UF_SYSTEM and UF_READONLY
in MSDOSFS.
It supported SF_ARCHIVED, but this has been
changed to be UF_ARCHIVE, which has the same
semantics as the DOS archive attribute instead
of inverse semantics like SF_ARCHIVED.
After discussion with Bruce Evans, change
several things in the msdosfs behavior:
Use UF_READONLY to indicate whether a file
is writeable instead of file permissions, but
don't actually enforce it.
Refuse to change attributes on the root
directory, because it is special in FAT
filesystems, but allow most other attribute
changes on directories.
Don't set the archive attribute on a directory
when its modification time is updated.
Windows and DOS don't set the archive attribute
in that scenario, so we are now bug-for-bug
compatible.
smbfs_node.c,
smbfs_vnops.c: Add support for UF_HIDDEN, UF_SYSTEM,
UF_READONLY and UF_ARCHIVE in SMBFS.
This is similar to changes that Apple has
made in their version of SMBFS (as of
smb-583.8, posted on opensource.apple.com),
but not quite the same.
We map SMB_FA_READONLY to UF_READONLY,
because UF_READONLY is intended to match
the semantics of the DOS readonly flag.
The MacOS X code maps both UF_IMMUTABLE
and SF_IMMUTABLE to SMB_FA_READONLY, but
the immutable flags have stronger meaning
than the DOS readonly bit.
stat.h: Add definitions for UF_SYSTEM, UF_SPARSE,
UF_OFFLINE, UF_REPARSE, UF_ARCHIVE, UF_READONLY
and UF_HIDDEN.
The definition of UF_HIDDEN is the same as
the MacOS X definition.
Add commented-out definitions of
UF_COMPRESSED and UF_TRACKED. They are
defined in MacOS X (as of 10.8.2), but we
do not implement them (yet).
ufs_vnops.c: Add support for getting and setting
UF_ARCHIVE, UF_HIDDEN, UF_OFFLINE, UF_READONLY,
UF_REPARSE, UF_SPARSE, and UF_SYSTEM in UFS.
Alphabetize the flags that are supported.
These new flags are only stored, UFS does
not take any action if the flag is set.

Add support to physio(9) for devices that don't want I/O split and
configure sa(4) to request no I/O splitting by default.
For tape devices, the user needs to be able to clearly understand
what blocksize is actually being used when writing to a tape
device. The previous behavior of physio(9) was that it would split
up any I/O that was too large for the device, or too large to fit
into MAXPHYS. This means that if, for instance, the user wrote a
1MB block to a tape device, and MAXPHYS was 128KB, the 1MB write
would be split into 8 128K chunks. This would be done without
informing the user.
This has suboptimal effects, especially when trying to communicate
status to the user. In the event of an error writing to a tape
(e.g. physical end of tape) in the middle of a 1MB block that has
been split into 8 pieces, the user could have the first two 128K
pieces written successfully, the third returned with an error, and
the last 5 returned with 0 bytes written. If the user is using
a standard write(2) system call, all he will see is the ENOSPC
error. He won't have a clue how much actually got written. (With
a writev(2) system call, he should be able to determine how much
got written in addition to the error.)
The solution is to prevent physio(9) from splitting the I/O. The
new cdev flag, SI_NOSPLIT, tells physio that the driver does not
want I/O to be split beforehand.
Although the sa(4) driver now enables SI_NOSPLIT by default,
that can be disabled by two loader tunables for now. It will not
be configurable starting in FreeBSD 11.0. kern.cam.sa.allow_io_split
allows the user to configure I/O splitting for all sa(4) driver
instances. kern.cam.sa.%d.allow_io_split allows the user to
configure I/O splitting for a specific sa(4) instance.
There are also now three sa(4) driver sysctl variables that let the
users see some sa(4) driver values. kern.cam.sa.%d.allow_io_split
shows whether I/O splitting is turned on. kern.cam.sa.%d.maxio shows
the maximum I/O size allowed by kernel configuration parameters
(e.g. MAXPHYS, DFLTPHYS) and the capabilities of the controller.
kern.cam.sa.%d.cpi_maxio shows the maximum I/O size supported by
the controller.
Note that a better long term solution would be to implement support
for chaining buffers, so that that MAXPHYS is no longer a limiting
factor for I/O size to tape and disk devices. At that point, the
controller and the tape drive would become the limiting factors.
sys/conf.h: Add a new cdev flag, SI_NOSPLIT, that allows a
driver to tell physio not to split up I/O.
sys/param.h: Bump __FreeBSD_version to 1000049 for the addition
of the SI_NOSPLIT cdev flag.
kern_physio.c: If the SI_NOSPLIT flag is set on the cdev, return
any I/O that is larger than si_iosize_max or
MAXPHYS, has more than one segment, or would have
to be split because of misalignment with EFBIG.
(File too large).
In the event of an error, print a console message to
give the user a clue about what happened.
scsi_sa.c: Set the SI_NOSPLIT cdev flag on the devices created
for the sa(4) driver by default.
Add tunables to control whether we allow I/O splitting
in physio(9).
Explain in the comments that allowing I/O splitting
will be deprecated for the sa(4) driver in FreeBSD
11.0.
Add sysctl variables to display the maximum I/O
size we can do (which could be further limited by
read block limits) and the maximum I/O size that
the controller can do.
Limit our maximum I/O size (recorded in the cdev's
si_iosize_max) by MAXPHYS. This isn't strictly
necessary, because physio(9) will limit it to
MAXPHYS, but it will provide some clarity for the
application.
Record the controller's maximum I/O size reported
in the Path Inquiry CCB.
sa.4: Document the block size behavior, and explain that
the option of allowing physio(9) to split the I/O
will disappear in FreeBSD 11.0.

drm/i915: adjusted_mode->clock in the dp mode_fixup
... instead of changing mode->clock, which we should leave as-is.
After the previous patch we only touch that if it's a panel, and then
adjusted mode->clock equals adjusted_mode->clock. Outside of
intel_dp.c we only use ajusted_mode->clock in the mode_set functions.
Within intel_dp.c we only use it to calculate the dp dithering
and link bw parameters, so that's the only thing we need to fix
up.
As a temporary ugliness (until the cleanup in the next patch) we
pass the adjusted_mode into dp_dither for both parameters (because
that one still looks at mode->clock).
Note that we do overwrite adjusted_mode->clock with the selected dp
link clock, but that only happens after we've calculated everything we
need based on the dotclock of the adjusted output configuration.
Outside of intel_dp.c only intel_display.c uses adjusted_mode->clock,
and that stays the same after this patch (still equals the selected dp
link clock). intel_display.c also needs the actual dotclock (as
target_clock), but that has been fixed up in the previous patch.
v2: Adjust the debug message to also use adjusted_mode->clock.

Restructure the mbuf pkthdr to make it fit for upcoming capabilities and
features. The changes in particular are:
o Remove rarely used "header" pointer and replace it with a 64bit protocol/
layer specific union PH_loc for local use. Protocols can flexibly overlay
their own 8 to 64 bit fields to store information while the packet is
worked on.
o Mechanically convert IP reassembly, IGMP/MLD and ATM to use pkthdr.PH_loc
instead of pkthdr.header.
o Extend csum_flags to 64bits to allow for additional future offload
information to be carried (e.g. iSCSI, IPsec offload, and others).
o Move the RSS hash type enumerator from abusing m_flags to its own 8bit
rsstype field. Adjust accessor macros.
o Add cosqos field to store Class of Service / Quality of Service information
with the packet. It is not yet supported in any drivers but allows us to
get on par with Cisco/Juniper in routing applications (plus MPLS QoS) with
a modernized ALTQ.
o Add four 8 bit fields l[2-5]hlen to store the relative header offsets
from the start of the packet. This is important for various offload
capabilities and to relieve the drivers from having to parse the packet
and protocol headers to find out location of checksums and other
information. Header parsing in drivers is a lot of copy-paste and
unhandled corner cases which we want to avoid.
o Add another flexible 64bit union to map various additional persistent
packet information, like ether_vtag, tso_segsz and csum fields.
Depending on the csum_flags settings some fields may have different usage
making it very flexible and adaptable to future capabilities.
o Restructure the CSUM flags to better signify their outbound (down the
stack) and inbound (up the stack) use. The CSUM flags used to be a bit
chaotic and rather poorly documented leading to incorrect use in many
places. Bring clarity into their use through better naming.
Compatibility mappings are provided to preserve the API. The drivers
can be corrected one by one and MFC'd without issue.
o The size of pkthdr stays the same at 48/56bytes (32/64bit architectures).

sh: Reject ++ and -- in arithmetic.
POSIX does not require ++ and -- in arithmetic. It is probably more useful
to reject them than to treat ++x and --x as x silently.
Note that the behaviour of increment and decrement can be obtained via
(x+=1), ((x+=1)-1), (x-=1) and ((x-=1)+1).

Compact m_hdr by packing the type and flags fields into one uint32_t.
The mbuf type is an enumerator with only a handful of types in use and
thus reduced from int to 8bits allowing for 255 types to be specified.
Only 5 types have been in use for a long time.
The flags field gets the remaining 24 bits with 12 bits for global
persistent flags and 12 bits for protocol/layer specific overlays.
Some of the global flags/functionality can be moved to the csum_flags
or ext_flags bits in the future.
MT_VENDOR[1-4] and MT_EXP[1-4] types for vendor-internal and
experimental local mapping are added.
The size of m_hdr shrinks from 24/40 to 20/32bytes (32/64bit architectures).

Do not use "Enable Implied Seek" on enhanced floppy controllers. This
breaks the "2step" feature of the driver, e.g. in order to read 360
KiB media on a 1200 KiB drive.
As the only potential advantage of implied (vs. explicit) seeks is to
minimize the software effort, yet our driver always contained the
logic needed for explicit seeks, simply dropping implied seeks is the
best solution without introducing risks for new bugs. There is no
performance penalty, reading a 1440 KiB medium takes exactly the same
time with both, implied or explicit seeks.

with the lock exclusively held.
Convert hwpmc(4) to use these event handlers instead of having
kern_kldload() and kern_kldunload() invoke hwpmc(4) hooks whenever files are
loaded or unloaded. This has no functional effect, but simplifes the linker

To do this, a single 8-bit segment index is
passed to the display via the I2C address 30h.
Data from the selected segment is then immediately
read via the regular DDC2 address using a repeated
I2C 'START' signal.

drm/ttm: use ttm_bo_reserve_slowpath_nolru in ttm_eu_reserve_buffers, v2
This requires re-use of the seqno, which increases fairness slightly.
Instead of spinning with a new seqno every time we keep the current one,
but still drop all other reservations we hold. Only when we succeed,
we try to get back our other reservations again.
This should increase fairness slightly as well.
Changes since v1:
- Increase val_seq before calling ttm_bo_reserve_slowpath_nolru and
retrying to take all entries to prevent a race.

after due to having an active bo with an already freed drm_mm embedded in it,
freeing it a second time didn't end well.

ttm: on move memory failure don't leave a node dangling
if we have a move notify callback, when moving fails, we call move notify
the opposite way around, however this ends up with *mem containing the mm_node
from the bo, which means we double free it. This is a follow on to the previous
fix.

drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd try
This fixes up
commit e8e89622ed361c46bf90ba4828e685a8b603f7e5
Author: Daniel Vetter <daniel.vetter at ffwll.ch>

drm/ttm: fix fence locking in ttm_buffer_object_transfer
which leaves behind a might_sleep in atomic context, since the
fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix
is to revert the above commit and only take the lock where we need it,
around the call to ->sync_obj_ref.
v2: Fixup things noticed by Maarten Lankhorst:
- Brown paper bag locking bug.
- No need for kzalloc if we clear the entire thing on the next line.
- check for bo->sync_obj (totally unlikely race, but still someone
else could have snuck in) and clear fbo->sync_obj if it's cleared
already.

drm/ttm: Make ttm_bo_wait() call uninterruptible in page fault handler
This fixes a crash where a SIGLALRM, heavily used by X.Org, would
interrupt the wait, causing the page fault to fail and the "Xorg"
process to receive a SIGSEGV.

drm/ttm: Fix unmap of buffer object
Add a new ttm_bo_release_mmap() function to unmap pages in a
vm_object_t. Pages are freed when the buffer object is later released.
This function is called in ttm_bo_unmap_virtual_locked(), replacing
Linux' unmap_mapping_range(). In particular this is called when a buffer
object is about to be moved, so that its mapping is invalidated.
However, we don't use this function in ttm_bo_vm_dtor(), because the
vm_object_t is already marked as OBJ_DEAD and the pages will be
unmapped.

vga_pci: Add API to map the Video BIOS
Here are two new functions to map and unmap the Video BIOS:
void * vga_pci_map_bios(device_t dev, size_t *size);
void vga_pci_unmap_bios(device_t dev, void *bios);
The BIOS is either taken from the shadow copy made by the System BIOS at
boot time if the given device was used for the default display (i386,
amd64 and ia64 only), or from the PCI expansion ROM.
Additionally, one can determine if a given device was the default
display at boot time using the following new function:
void vga_pci_unmap_bios(device_t dev, void *bios);

drm/radeon: Import the Radeon KMS driver
This driver is based on Linux 3.8 and a previous effort by kan at .
More informations about this project can be found on the FreeBSD wiki:
https://wiki.freebsd.org/AMD_GPU
The driver is split into:
sys/dev/drm2:
The driver sources.
sys/modules/drm2/radeonkmw:
The driver main kernel module's Makefile.
sys/modules/drm2/radeonkmsfw:
All firmware kernel module Makefiles. There's one directory and one
Makefile for each firmware.
sys/contrib/dev/drm2/radeonkmsfw:
All firmware binary sources.
tools/tools/drm/radeon
Tools to update firmwares or regenerate some headers.
Merging the driver to FreeBSD 9.x may be possible but not a priority for
now.

Fix fcntl F_GETFL F_SETFL for files opened execute-only (O_EXEC).
The FFLAGS and OFLAGS now work correctly also for files opened with O_EXEC.
Except possibly fuse, the other users pass values without O_EXEC set. fuse
appears to assume O_EXEC is handled correctly.
Although F_SETFL may not be commonly used for execute-only file descriptors,
F_GETFL may be useful to find the access mode.

Implement the ip, tcp, and udp DTrace providers. The probe definitions use
dynamic translation so that their arguments match the definitions for
these providers in Solaris and illumos. Thus, existing scripts for these
providers should work unmodified on FreeBSD.
