The memory size alignment workaround for a TLB bug on gfx802 was
breaking userptrs because it would attempt to get_user_pages beyond
the end of a VMA. Refine this workaround based on our understanding
of the HW bug. It only affects L2 cacheline allocation, which is
decided by the last page in the cache line (8 entries = 32KB of
address space). Thus aligning memory allocation so that the last
page falls on the end of a 8 entry TLB cache line allows caching
to work correctly.
Imported images require specific alignments. If their size is not
naturally aligned with 8 cache lines, it may have bad TLB cache
performance.
This patch will only have the desired effect if redundant size
padding in KFD is also removed.

sdma end ts must be 256 bit aligned in oss 3.0 and prior. Using
the ts pool requires copying into the signal and is a significant
performance penalty for small copies.
SharedSignal is 128 bytes due to alignment so can host the end ts.
Move sdma end ts into SharedSignal and remove ts pool and ts copy.

child process clone vm objects from svm->apertures if parent process
doesn't free memory before fork. fmm_clear_all_mem suppose to clear the
apertures in forked child process but this only works if gpu_vm is not
NULL. parent process call hsaKmtCloseKFD reset gpu_vm to NULL and then
fork, then child process will not clear svm->apertures.
As a result, the child process will allocate vm object with same address
and add to aperture, there are duplicate vm objects with same address
in aperture. Then mapping to GPU will find the wrong vm object and
create incorrect GPU mapping cause rocrtst IPC test VM fault. The issue
happened with HSA_USERPTR_FOR_PAGED_MEM=1.
The fix is to clear vm objects in all apertures in clear_after_fork.

This reverts commit 632ad3a749.
This change causes KFDTest failed on gfx803. The first hsaKmtCreateEvent
call allocate system memory for events_page because global variable
events_page is NULL. And this events page vm address should not be freed
until the process exit.
The change to destrory objects in hsaKmtCloseKFD removes events page. As
a result, KFDTest call hsaKmtOpenKFD again and then allocate memory will
get same events_page vm address on gfx803, and map this vm failed because
the vm conflict with events_page mapping.
KFDTest passed on VG10, gfx906 because allocate memory get different vm
address. hsaKmtCreateEvent still works fine as the driver keeps the
events page mapping of the process.
We should only destroy objects in fork cloned child process regardless
if gpu_vm is NULL or not.

/proc/cpuinfo are opened, read, and closed multiple times. Once for vendor
name and multiple times for model name -- each node opens once. For example
in a 2 CPUs + 4 GPUs system, it'll be opened 7 times. This patch reads it
one time and stores it in a cpuinfo buffer. This cpuinfo buffer is freed
when the snapshot is done.
Also replace returns with gotos inside the snapshot to avoid possible
