[ROCm/ROCR-Runtime commit: 19dacdecd3]
Query GPUVM aperture limits of all dGPUs to determine SVM aperture
base and limit. This depends on a recent KFD change that reports
the GPUVM apurture limits for dGPUs in the
AMDKFD_IOC_GET_PROCESS_APERTURES_NEW ioctl (drm/amdkfd: Simplify
dGPU SVM aperture handling).
Only initialize SVM aperture once, instead of once per GPU.
Don't call AMDKFD_IOC_SET_PROCESS_DGPU_APERTURE. It's not needed any
more and will not be upstreamed.

On discrete GPUs place the EOP queue in VRAM. The reader/writer of this
queue is the CP and the size is small. Dispatch latency improves
through lower read latency in AQL completion phase.

Invisible device memory is mmapped as PROT_NONE.
Normal CPU access to the memory is still not allowed but
struct vm_area_struct will be created for the memory address
so ptrace can access the memory via the vma.

UCX test cases are reporting uninitialized values when CMA fails. The
application should ideally ignore SizeCopied when the function fails but
it doesn't. This is leading to wrong diagnosis.
v2: Fill in partial SizeCopied in case of failure

This reverts commit dbd9a8736c,
Plus a bug fix to patch "Cleanup fmm.c":
Call id_in_array with correct parameter. The third parameter
of id_in_array is size in byte of the array, not the number
of array items. Call it correctly.

to fmm_allocate_memory_object. This function name was confusingly
similar to fmm_allocate_device and __fmm_allocate_device. The new name
reflects its function better: allocate the VM object and the kernel
mode buffer object.

Prefer using memfd_create() for the ring buffer.
We were using /dev/shm, but this won't work on systems that
either don't have /dev/shm or have mounted it with noexec, because
for everything other than gfx700 we map the ring buffer with PROT_EXEC.
memfd_create() is Linux specific and was added in Linux 3.17, so we
will fallback to using /dev/shm on systems where memfd_create() is
not available.

Corrected semantics used in hsa_queue_load_write_index_relaxed.
The semantics that was used in hsa_queue_load_write_index_relaxed
didn't seem to match the name of the function.
I also removed a useless return keyword.
