arm64: Set __nocfi on swsusp_arch_resume()
A DABT is reported[1] on an android based system when resume from hiberate.
This happens because swsusp_arch_suspend_exit() is marked with SYM_CODE_*()
and does not have a CFI hash, but swsusp_arch_resume() will attempt to
verify the CFI hash when calling a copy of swsusp_arch_suspend_exit().
Given that there's an existing requirement that the entrypoint to
swsusp_arch_suspend_exit() is the first byte of the .hibernate_exit.text
section, we cannot fix this by marking swsusp_arch_suspend_exit() with
SYM_FUNC_*(). The simplest fix for now is to disable the CFI check in
swsusp_arch_resume().
Mark swsusp_arch_resume() as __nocfi to disable the CFI check.

sched/fair: Revert force wakeup preemption
This agressively bypasses run_to_parity and slice protection with the
assumpiton that this is what waker wants but there is no garantee that
the wakee will be the next to run. It is a better choice to use
yield_to_task or WF_SYNC in such case.
This increases the number of resched and preemption because a task becomes
quickly "ineligible" when it runs; We update the task vruntime periodically
and before the task exhausted its slice or at least quantum.
Example:
2 tasks A and B wake up simultaneously with lag = 0. Both are
eligible. Task A runs 1st and wakes up task C. Scheduler updates task
A's vruntime which becomes greater than average runtime as all others
have a lag == 0 and didn't run yet. Now task A is ineligible because
it received more runtime than the other task but it has not yet
exhausted its slice nor a min quantum. We force preemption, disable
protection but Task B will run 1st not task C.

sched/fair: Disable scheduler feature NEXT_BUDDY
NEXT_BUDDY was disabled with the introduction of EEVDF and enabled again
after NEXT_BUDDY was rewritten for EEVDF by commit e837456fdca8 ("sched/fair:
Reimplement NEXT_BUDDY to align with EEVDF goals"). It was not expected
that this would be a universal win without a crystal ball instruction
but the reported regressions are a concern [1][2] even if gains were
also reported. Specifically;
o mysql with client/server running on different servers regresses
o specjbb reports lower peak metrics
o daytrader regresses
The mysql is realistic and a concern. It needs to be confirmed if
specjbb is simply shifting the point where peak performance is measured
but still a concern. daytrader is considered to be representative of a
real workload.
Access to test machines is currently problematic for verifying any fix to

x86: make page fault handling disable interrupts properly
There's a big comment in the x86 do_page_fault() about our interrupt
disabling code:
* User address page fault handling might have reenabled
* interrupts. Fixing up all potential exit points of
* do_user_addr_fault() and its leaf functions is just not
* doable w/o creating an unholy mess or turning the code
* upside down.
but it turns out that comment is subtly wrong, and the code as a result
is also wrong.
Because it's certainly true that we may have re-enabled interrupts when
handling user page faults. And it's most certainly true that we don't
want to bother fixing up all the cases.
But what isn't true is that it's limited to user address page faults.
