When compiling with -O0, some compilers generate a xchg instruction for
the __atomic_store(...) built-in. Using xchg on MMIO memory is
undefined-behavior and may be ignored on certain CPUs.

Random driver deadlock on svm_range_evict_svm_bo_worker() is obeserved on
NPS2/DPX mode. It's seen with xnack off and happens more often on the
partition with less VRAM because of TMR.
Temporarily skip SVM Evict tests on Family AV when xnack is disabled.

[ROCm/ROCR-Runtime commit: 5e28208cec]
Adds a bool to the GPU agent and a public member method to
check if the GPU supports large BAR. This is needed so we can
check if large BAR is supported when a user tries to allocate
an AQL queue in device memory on a given GPU agent.
Also adds an exception to the AQL queue if device-side AQL queues
are requested and the GPU owner of the AQL doesn't support large
BAR. Otherwise, ROCr will currently allow device-side queues
that can cause faults when the user tries to touch their ring
buffers and the user will not know why the faults are occuring.
This relies on the fact that the KFD does not exposed any links
from the CPU to the GPU if large BAR is not enabled (though
links from the GPU to the CPU may still be exposed by the KFD).
[ROCm/ROCR-Runtime commit: f2c482d923]
This builds on a prior change that allowed for allocating
a user-mode queue's packet buffer in device memory to also
allocate the queue struct in device memory. This provides
additional latency benefits particularly for cases where
dispatches are performed from the GPU itself. Flags are
added to support the various use cases.

The max queues per process is 1024 in KFD,
KFDQMTest.OverSubscribeCpQueues fails with multi-gpu mode

changing MAX_CP_QUEUES to adapt it will fix the issue.

Use spaces consistently to format the trap handler code. This patch
does not introduce any change in the trap handler. Using `git show -w`

Make sure to clear the HOST_TRAP and PERF_SNAPSHOT bits before returning
from the second level trap handler. As those bits are sticky, this
ensures future re-entry to the trap handler (for context save for
example) will not be confused with a sampling trap.
