By using user-allocated pages instead of kernel-allocated pages
from TTM, we're not subject to TTM's self imposed limits on kernel
memory usage. This also paves the way for for more wide-spread use
of HMM on upstream kernels.

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
memory leak.

If M0[23] is set then the driver will interpret the interrupt as a
debug event, rather than a signal event.
Clear M0 before sending the interrupt. All paths here are terminal so
it's not necessary to save/restore M0.

child process will duplicate the vm_objects from the parent.
