KFD added all direct IO links to sysfs, so this patch removes all direct
links related code and modify the indirect links function to reflect the
change.

Guard pages help catch out-of-bounds memory accesses by applications
by generating VM faults (GPU) and segfaults (CPU).
Remove address space reservation from scratch aperture. That address
space is managed by the Thunk client. Guard pages would cause Thunk's
address space management to get out of sync with the client's.

Many devices have the same counter IDs for the hardware block. Devices
in the same GFX generation usually have the same block counters. No need
to list each device individually. Instead, have a table to share with all
devices that have the same counter IDs, and have separated tables for
devices that don't have the same counter IDs.

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.

Unless HSA_USERPTR_FOR_PAGED_MEM is explicitly set, don't use userptr

all usage once those issues are resolved.

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.

[ROCm/ROCR-Runtime commit: 1025579c0b]
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.

CWSR buffers can be large on dGPUs (~21MB on gfx803). Allocating them
in VRAM limits the number of queues that can be created unnecessarily.
Also make freeing of per-queue buffers symmetric with allocation. All
buffers are now allocated with allocate_exec_aligned_memory on dGPUs
and APUs, so use free_exec_aligned_memory to free them.
