Since access may only be manipulated on whole pages, suballocator fragments must cooperate to set the page's access.
Since the KFD does not migrate memory on access changes this implementation makes agent access sticky across the requests in a fragmented page.

GCC can't reasonably be told that the lock ptr isn't null. Adding a private bool
allows the branch to be eliminated, along with the bool.

Blocks inside of HsaCounterProperties structure is not a fixed size. It
varies with number of counters in the block -- size of Counters in
HsaCounterBlockProperties is different in every block. Current
implementation assumes fixed size and the next block will overwrite the
previous block's Counters. This patch change the array implementation to
using a pointer so it'll move the next block to the correction position.

[ROCm/ROCR-Runtime commit: 117fa5034b]
Applications may try to allocate lots host memory and reaches the mmap
limit (/proc/sys/vm/max_map_count). When Applications fails to allocate
memory and calls hsaKmtFreeMemory to release the memory, Thunk fails to
reduce the maps count so the following hsaKmtAllocMemory calls continue
to fail, which doesn't make sense to the application. This patch checks
the mmap to NORESERVE return value. If it fails and the error number is
ENOMEM, reduce the map count by munmap and map it again immediately.

Use the mapped_device_id_array size when allocating temp_node_id_array
for unmapping queues in fmm_map_to_gpu_nodes. registered_device_id_array
size may be 0. Also, this temporary array is small enough to allocate it
on the stack. Malloc and free are overkill here.
Fix potential memory leak when registering the same device ID array
multiple times.

[ROCm/ROCR-Runtime commit: 395ecaa985]
IOMMU path in sysfs was amd_iommu. After implementing multiple devices
support, the path is replaced with amd_iommu_<index>. Current Thunk spec
is not clear about how to support multiple instances in one block. There
is no products having multiple IOMMUs yet at this point. This patch
changes the path to support both amd_iommu and amd_iommu_0 for Carizo.
