This avoids unnecessary evictions and failed restores due to the
munmap of userptr BOs that are just about to be freed.

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.

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.

gfx802 requires a workaround for a VM TLB bug in which lookups use

Until this is fixed in amdgpu the GPUVM doorbell logic will fail.

Allocate doorbells for dGPUs in the SVM aperture and map them for

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 CPUVM aperture to keep track of memory allocation that is not known
to GPU driver. Together with GPUVM, this patch adds the pointer attributes
support to APU.

Add two pointer attributes APIs:
hsaKmtQueryPointerInfo - allow the user to query the memory information
using a pointer. This pointer can point to any address inside the
range known to HSA.
hsaKmtSetMemoryUserData - allow the user to attach data to a pointer to
add memory tracking information. This pointer must match the start
address of a memory allocation or registration.
TODO: This patch implements support on dGPU. Needs to add APU.

In a NUMA system, topology should report NumCaches as the number of caches
within the node but current code reports the total caches in the system. This
patch fixes the error. This patch also uses cpuid to get cache information
instead of reading from sysfs files. See "Intel Corporation, Intel 64 and IA-32
Architectures Software Developer's Manual Volume 2(2A, 2B & 2C) Instruction
Set Reference" 3-179 for cpuid instruction features used in this patch.

All files should go into /opt/rocm/$component
For developer convenience, a single include directory is created through
symlinks, from the component include directory to /opt/rocm/include.
Similarly, a unified linked directory is present in /opt/rocm/lib
The component lib directory should not include linker names (library
names without version numbers).
This commit also fixes 'make rpm' running correctly without the need for
sourcing build/envsetup.sh
