The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in
a rather nasty way by re-defining it to zero. That is infinitely
fragile and makes it very hard to see what to code really does in
a given context. The very same constant has different meanings and
values - depending on which subarch is enabled.

propagating the right values into the genapic driver templates.

drm: Rip out the racy, unused vblank signal code.

Schedule a vblank signal, kill the process, and we'll go walking over freed
memory.  Given that no open-source userland exists using this, nor have I
ever heard of a consumer, just let this code die.

powerpc/mm: Fix handling of _PAGE_COHERENT in BAT setup code

_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL.
Thus it has to be masked out, if the BAT mapping should be non
cacheable or CPU_FTR_NEED_COHERENT is not set.

This will work on normal SMP setups because we force-set
CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

powerpc/pseries: Correct VIO bus accounting problem in CMO env.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE.  Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE.  Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system.  Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.

Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should.  Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.
