svn commit: r234180 - in stable/8/sys: amd64/include i386/conf i386/include mips/include powerpc/include

New Revision: 234180
URL: http://svn.freebsd.org/changeset/base/234180

Log:
  MFC 233670,233671:
  - Use VM_MEMATTR_UNCACHEABLE for the constant for UC memory rather than
    VM_MEMATTR_UNCACHED on mips.
  - Rename VM_MEMATTR_UNCACHED to VM_MEMATTR_WEAK_UNCACHEABLE on x86 to
    be less ambiguous and more clearly identify what it means.  An alias
    from VM_MEMATTR_WEAK_UNCACHEABLE to VM_MEMATTR_WEAK_UNCACHED remains
    on x86 to preserve the KPI.
  - Remove the VM_MEMATTR_UNCACHED alias from powerpc.
