This should allow us to take advantage of BigK fragments and huge pages
and improve TLB efficiency for VRAM allocations. Huge pages only work
with 4-level page tables (gfx900 and up). BigK fragments work on older
GPUs.

Imported graphics buffers are most likely images. Align them for
tiled image access. 64KB seems to do the trick.
This fixes VM faults with OpenCL graphics interop.

1. Correct amd::AqlQueue::ExecutePM4 to support interception.
2. Minor fixes to AqlPacket and SoftCP.
3. Minimal change to disable interception of runtime internal queues.

Performance counters have limited slots for concurrent profiling. We
need a mechanism to synchronize the slots access across different
processes. Lock file file was first used for this access control. It
reveals a RedHat bug that /var/lock, symbolic linked to /run/lock, is
not writable by others. To avoid this bug and to simplify the code,
POSIX shared memory is created to replace the lock file usage. Access
of the shared memory is controlled by semaphores.

Hardware block testing is done with the workgroup state offset
initialized to the control stack size on all ASICs. MEC microcode
assumes this space is available when the workgroup state offset is
reset after a context restore event.
Fixes context save area overrun when the full save area is used.

Libraries normally don't print messages. We use pr_err, pr_warn,
pr_info, and pr_debug to print messages to stderr when prints are
enabled for debugging.

Existing Thunk has printf/fprintf in the code while normally libraries
don't print any message. This patch introduces a print machenism similar to
how the Linux kernel prints to console based on the log level. The default
is not to print any message, but setting HSAKMT_DEBUG_LEVEL will enable the
prints.

For experimental purpose, we need an option to change compute capability
by forcing the GfxIp version. This patch allows to use environment
variable HSA_OVERRIDE_GFX_VERSION=major.minor.stepping to replace the
default version. For example:
export HSA_OVERRIDE_GFX_VERSION=9.0.1

When a fatal memory fault occurs the scheduler context-saves all queues
in the process and notifies the runtime through the memory event. The
saved state contains all GPR/LDS data at the moment of the fault.
Retrieve this state and present it to the user if HSA_DEBUG_FAULT is set
to "analyze" and the wavefront caused the fault. If amdgcn-capable objdump
is in the PATH invoke this to disassemble code around the PC.
Queue lifetime is now managed by the runtime to allow querying the
context save state for all active queues.

mask information is maintained in Thunk, and others (queue detail error
and queue type extended) are ignored (value = 0) at this point.

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs
Also use this opportunity to spell manageable properly

Use calloc to allocate event data. Otherwise random data may be filled
in for events that haven't actually signalled. This could trigger the
VM fault handler in the Runtime when no VM fault actually happened and
lead to intermittent HSA conformance test failures.
