child process.

CWSR buffers can be large on dGPUs (~21MB on gfx803). Allocating them
in VRAM limits the number of queues that can be created unnecessarily.
Also make freeing of per-queue buffers symmetric with allocation. All
buffers are now allocated with allocate_exec_aligned_memory on dGPUs
and APUs, so use free_exec_aligned_memory to free them.

Also emit error messages to stderr if no async queue error callback was registered and queue fault messages are enabled (on by default).
Queue fault messages are controlled with env key HSA_ENABLE_QUEUE_FAULT_MESSAGE.

Uncommented HSA IPC code.
Changed hsa_amd_ipc_memory_t to be 8 uint32_t's instead of 9 to
match spec

Implement three new APIs for IPC buffer sharing:
-hsaKmtShareMemory()
-hsaKmtRegisterSharedHandle()
-hsaKmtRegisterSharedHandleToNodes()
Add new ioclts necessary for the above APIs.

A memory region is allowed to be registered multiple times when the memory
is specified by a user pointer. If it's registered with the same user
pointer but with different sizes, it's treated as different instances and
multiple VM objects are created with different GPU address.

Currently, if a process' parent called hsaKmtOpen, the child will be
unable to open a connection to KFD, since kfd_open_count will be > 0.
When forking, the refcount should be reset, in order to allow the child
to re-open /dev/kfd.

Ensure that the write index and ring buffer contents are visible
to the HW before sending the doorbell. The latter is a write-combined
MMIO store and must be ordered with prior cacehable non-MMIO stores.
Also be more explicit about memory semantics for doorbell stores.

gfx802 requires a workaround for a VM TLB bug in which lookups use
the ACTIVE bit of the 8th PTE within any aligned group of 8 PTEs.
Until this is fixed in amdgpu the GPUVM doorbell logic will fail.

If we issue too many copy commands without syncing and wrapping happens,
we need to wait for the blits to be done before moving forward otherwise
we will overwrite the kernel args of the blits in flight.

Allocate doorbells for dGPUs in the SVM aperture and map them for
GPU access. This is necessary to allow GPU-initiated submissions to
user mode queues.
Depends on new doorbell BO allocation flag in KFD.

CPU cache information reported by Thunk topology is obtained from cpuid
instruction. This instruction only applies to X86 systems. It can cause
compile errors on non-X86 platforms. This patch temporarily disables CPU
cache functions in topology for non-X86 platforms in order to compile.

Add vm_find_object_by_userptr_range so QueryPointerInfo can find the
object as well when the pointer is not the starting address but it's
inside the memory range. Also rename vm_find_object_xxx functions to
_by_address and _by_address_range to be consistent.
