drm/amd/display: Simplify the per-CPU usage.
The fpu_recursion_depth counter is used to ensure that dc_fpu_begin()
can be invoked multiple times while the FPU-disable function itself is
only invoked once. Also the counter part (dc_fpu_end()) is ballanced
properly.
Instead of using the get_cpu_ptr() dance around the inc it is simpler to
increment the per-CPU variable directly. Also the per-CPU variable has
to be incremented and decremented on the same CPU. This is ensured by
the inner-part which disables preemption. This is kind of not obvious,
works and the preempt-counter is touched a few times for no reason.
Disable preemption before incrementing fpu_recursion_depth for the first
time. Keep preemption disabled until dc_fpu_end() where the counter is
decremented making it obvious that the preemption has to stay disabled
while the counter is non-zero.
Use simple inc/dec functions.
Remove the nested preempt_disable/enable functions which are now not
needed.

drm/amd/display: Remove migrate_en/dis from dc_fpu_begin().
This is a revert of the commit mentioned below while it is not wrong, as
in the kernel will explode, having migrate_disable() here it is
complete waste of resources.
Additionally commit message is plain wrong the review tag does not make
it any better. The migrate_disable() interface has a fat comment
describing it and it includes the word "undesired" in the headline which
should tickle people to read it before using it.
Initially I assumed it is worded too harsh but now I beg to differ.
The reviewer of the original commit, even not understanding what
migrate_disable() does should ask the following:
- migrate_disable() is added only to the CONFIG_X86 block and it claims
to protect fpu_recursion_depth. Why are the other the architectures
excluded?
- migrate_disable() is added after fpu_recursion_depth was modified.
Shouldn't it be added before the modification or referencing takes
place?
Moving on.
Disabling preemption DOES prevent CPU migration. A task, that can not be
pushed away from the CPU by the scheduler (due to disabled preemption)
can not be pushed or migrated to another CPU.
Disabling migration DOES NOT ensure consistency of per-CPU variables. It
only ensures that the task acts always on the same per-CPU variable. The
task remains preemptible meaning multiple tasks can access the same
per-CPU variable. This in turn leads to inconsistency for the statement
*pcpu -= 1;
with two tasks on one CPU and a preemption point during the RMW
operation:
Task A Task B
read pcpu to reg # 0
inc reg # 0 -> 1
read pcpu to reg # 0
inc reg # 0 -> 1
write reg to pcpu # 1
write reg to pcpu # 1
At the end pcpu reads 1 but should read 2 instead. Boom.
get_cpu_ptr() already contains a preempt_disable() statement. That means
that the per-CPU variable can only be referenced by a single task which
is currently running. The only inconsistency that can occur if the
variable is additionally accessed from an interrupt.
Remove migrate_disable/enable() from dc_fpu_begin/end().
