Though S_IWOTH flag is set in the open() call, the lock file is not
created as accessable by others if others try to open the file with O_RDWR
permission. It's because the default umask masks off S_IWOTH. This patch
changes the umask to S_IXOTH since others don't need that permission but
it'll open up S_IWOTH. Restore the umask to original after the file is
opened.

StartTrace and StopTrace send ioctl requests to enable/disable performance
counters. QueryTrace reads the counter from the perf_event fd.

Unless HSA_USERPTR_FOR_PAGED_MEM is explicitly set, don't use userptr
for all paged memory. This will also allow us to work around some 4.9
issues, and then we can explicitly set HSA_USERPTR_FOR_PAGED_MEM for
all usage once those issues are resolved.

On SOC15 chips, the ABI for the create_queue ioctl is changed to
allow doorbell allocation independent of the queue ID. This is
necessary to accommodate doorbell routing to specific engines in
the BIF.

This is in preparation for gfx900, which uses 64-bit doorbells. We
maintain the same number of doorbells per process by making the
doorbell page size bigger.
KFD will need to implement the same rule.

Existing code uses lockf to ensure exclusive PMC access of one process and
one TraceId. However Thunk spec allows hsaKmtPmcAcquireTraceAccess to get
exclusive access to the defined set of counters, not exclusive to one
process or one TraceId. Multiple counter sets of multiple TraceIds is
allowed if they meet the concurrent access limit evaluated by the hardware
/driver.

Existing code assumes all counters sent to hsaKmtPmcRegisterTrace belong
to one PMC block and this block is SQ. This patch considers cases when
counters are in different blocks, and removes the hard-coded SQ. As a
matter of fact, SQ is non-privileged so the user even shouldn't use SQ
counters to register/release trace. This patch also ignores
non-privileged blocks as what HSA Thunk spec describes.
This patch also records counters information in trace structure so
AcquireTrace can get counters information using that TraceId.

Gfx9 requires monotonic write pointer and doorbell.
Cound fields are 1-based compared with 0-based pre-Gfx9.

- Remove redundant submission size checks (handled by AcquireWriteAddress)
- Unify copy/fill per-command limit (documentation is unclear)
