  Log:
  - Merge sys/sparc64/pci/psycho.c rev. 1.8:
    Map the device memory belonging to resources of type SYS_RES_MEMORY into
    KVA upon activation so that rman_get_virtual() works as expected.
  - In sbus_alloc_resource() checking whether toffs is 0 as an indication
    that no applicable child range was found isn't appropriate as it's
    perfectly valid for the requested SYS_RES_MEMORY resource to start at
    the beginning of a child range. So check for the RMAN still being NULL
    instead.
  - As a minor runtime speed optimization break out of the loop where we
    search for the applicable child range in sbus_alloc_resource() as soon
    as it's found.
  - Let sbus_setup_intr() return ENOMEM rather than 0 if it can't allocate
    memory for the interrupt clearing info.
  - Actually do what the comment in sbus_setup_intr() says and disable the
    respective interrupt while fiddling with it.
  - Remove some superfluous INTVEC() around inr, which already only contains
    the interrupt vector, in sbus_setup_intr().
  - While here, fix a style(9) bug in sbus_setup_intr() (don't use function
    calls in initializers).
  
  The first two changes are required for a CG6 driver.
