In VM with 6vcpu, cpu schedule of
queue_delayed_work(system_freezable_wq) is lower than BM.
HSA_SMI_EVENT_QUEUE_RESTORE event from case HMMProfilingEvent/0 got
delayed execution and caused HMMProfilingEvent/1 fail.
The fix is only listen to HSA_SMI_EVENT_MIGRATE_START event and ignore
all other events.

We had skipped doing it for PAGE_SIZE, but it should be left as the
regular PAGE_SHIFT name, especially for users who are using different
headers. We want PAGE_SHIFT and PAGE_SIZE to be consistent with one
another, so set them both explicitly to the same value if either
of them is undefined

To support fully-static library ROCm builds, ensure that all global
symbols are prefixed with something meaningful to avoid collisions with
other libraries
A script was made using" objdump -C -t" to get a list of symbols,
then checking if the global symbols have a meaningful prefix (for thunk:
hsakmt or kmt in various cases)

Fix for some places where the ISA buffers are not declared as
executable. Previous code in Thunk was blindly setting exec bit on all
memory allocations so this issue was masked.

Since the amdgpu driver commit 1f4ac94b59aebebf.

gtt and vram are available for compute.
So, the vramSize obtained by function GetSysMemSize is actually about 50% system memory.
But small APUs don't have large system memory, and kernel memory limit is smaller for them.
Therefore, it will fail to register SVM Range for SysBuffer and SysBuffer2.
Example:
System Memory size: 3373M Kernel memory limit:1791M
VRAM Memory Size: 256M GTT Memory Size: 1686M

Small APUs use same memory allocation approach with APP APU now,
skip these tests as well.
