Use the aligned size of the buffer objects for CPU unmapping in
__fmm_release instead of relying on the unaligned size passed in by
the caller.

Allocate SVM address space for the registered memory and use new
userptr support in KFD to create a system memory BO associated with
the given user pointer. Map this BO at the SVM address for CPU
access.
MapMemoryToGPU can be used with the registered user pointer and
will return the SVM address as alternate GPUVA.

Few more counters are now available in GFX8 register specs. So adding

Allocations from GPU nodes will return VRAM, not system memory.
Only non-paged allocation from GPU nodes is supported. System
memory can only be allocated from CPU nodes (usually node 0).
The HostAccess flag is no longer used to distinguish the memory
type. It only indicates, whether the memory is mapped for CPU
access.
Maintain compatibility with broken KfdTests by returning system
memory for paged-memory requested from GPU nodes.

This is thunk part of the CWSR support.
1. SDMA queue don't support CWSR , no necessary to allocate the context save/restore memory
2. Allocate the context save/restore memory in local frame buffer for dGPU

All tonga page size alignment is done in the memory management
functions in fmm.c. All other code only specifies the minimum
alignment it needs and lets fmm.c handle the HW-specific
alignment.
Clean up aligned-exec memory allocation in queue.c to remove
hard-coded TONGA_PAGE_SIZE alignments and remove code duplication.
Make sure alignments are consistent between allocate and free.

HSA thunk API returns null when querying for GPU node marketing
names due to empty system topology file.
- Add marketing names to device GFX IP data structs.
- Modify name retrieval to pull from data structs instead of file.

This prevents the library from being unloaded at runtime, even when
dlclose is called. This preserves global variables, such as state
about the SVM address space and avoids catastrophic leaks on dlclose.

Stop using NUM_OF_SUPPORTED_GPUS. For now the definitions itself cannot
be removed as ioctl code is in upstream Kernel.

Fix hsaKmtRegisterMemory to be a no-op for now and move the multi-GPU
implementation to hsaKmtRegisterMemoryToNodes. Make GPU memory mappings
of host memory visible to all GPUs by default. Device memory is still
visible to the allocating GPU only by default (but can be overridden
with hsaKmtRegisterMemoryToNodes for experimenting with P2P).

When the Thunk is initialized multiple times in the lifetime of a single process
, some global resources are leaked. This can happen when dlopen and dlclose are
used to load the library at runtime, rather than linking the runtime against
the Thunk. This patch adds the destructor to release global resources when
dlclose is called.

Previous code only works for systems where shared_cpu_map lists 32 or less
bits. Some systems list more than 32 bits and express them as
XXXXXXXX,XXXXXXXX,.... This patch adds that calculation. Also increase
MAX_CPU_CORES and MAX_CACHES to accommodate more advanced systems.

By adding REL=1 to the make command line (e.g. make REL=1 deb), we can
create a release build of the Thunk. This will not affect existing
functionality, and will only have an effect if REL=1 is specified on the
command line, or in the build_thunk.sh script.
