The system and GPU MMU page size might differ, which becomes a
problem for FW sections that need to be mapped at explicit addresses
since our PAGE_SIZE alignment might cover a VA range that's
expected to be used for another section.
Make sure we never map more than we need.
Changes in v3:
- Add R-bs
Changes in v2:
- Plan for per-VM page sizes so the MCU VM and user VM can
have different pages sizes

There are error messages like below that are occurring during stress
testing: "[ 31.004009] xe 0000:03:00.0: [drm] ERROR GT0: Global
invalidation timeout". Previously it was hitting this 3 out of 1000
executions of warm reboot. After raising it to 500, 1000 warm reboot
executions passed and it didn't fail.
Due to the way xe_mmio_wait32() is implemented, the timeout is able to
expire early when the register matches the expected value due to the
wait increments starting small. So, the larger timeout value should have
no effect during normal use cases.
v2 (Jonathan):
- rework the commit message
v3 (Lucas):
- add conclusive message for the fail rate and test case
v4:
- add suggested-by

[Why&How]
Disabling P-State support on full updates for DCN401 results in
introducing additional communication with SMU. A UCLK hard min message
to SMU takes 4 seconds to go through, which was due to DCN not allowing
pstate switch, which was caused by incorrect value for TTU watermark
before blanking the HUBP prior to DPG on for servicing the test request.
Fix the issue temporarily by disallowing pstate changes for compliance
test while test request handler is reworked for a proper fix.

[Why&How]
vblank immediate disable currently does not work for all asics. On
DCN401, the vblank interrupts never stop coming, and hence we never
get a chance to trigger idle optimizations.
Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

Pull ftrace fixes from Steven Rostedt:
"A couple of fixes to function graph infrastructure:
- Fix allocation of idle shadow stack allocation during hotplug
If function graph tracing is started when a CPU is offline, if it
were come online during the trace then the idle task that
represents the CPU will not get a shadow stack allocated for it.
This means all function graph hooks that happen while that idle
task is running (including in interrupt mode) will have all its
events dropped.
Switch over to the CPU hotplug mechanism that will have any newly
brought on line CPU get a callback that can allocate the shadow
stack for its idle task.
- Fix allocation size of the ret_stack_list array
When function graph tracing converted over to allowing more than
one user at a time, it had to convert its shadow stack from an
array of ret_stack structures to an array of unsigned longs. The
shadow stacks are allocated in batches of 32 at a time and assigned
to every running task. The batch is held by the ret_stack_list
array.
But when the conversion happened, instead of allocating an array of
32 pointers, it was allocated as a ret_stack itself (PAGE_SIZE).
This ret_stack_list gets passed to a function that iterates over
what it believes is its size defined by the
FTRACE_RETSTACK_ALLOC_SIZE macro (which is 32).
Luckily (PAGE_SIZE) is greater than 32 * sizeof(long), otherwise
this would have been an array overflow. This still should be fixed
and the ret_stack_list should be allocated to the size it is
expected to be as someday it may end up being bigger than
SHADOW_STACK_SIZE"
