On arm systems the spin on owner optimization can intermittently cause a
lockup that's usually as long as the waiting thread's cpu timeslice. The
repeated mutex aquisitions + atomics in a single spinning thread can
completely lock out the owner from releasing the kernel mutex. The
owner needs to acquire a spinlock on the relase path and this spinlock
can share a monitor with the other locks and atomics on the waiter path.
Rate limit the waiter so that the thread releasing the mutex never
is starved.

When a system is entering RPM assisted sleep, the NOACK messages are
not accounted in preventing such sleep modes as no driver is waiting
on it. In such scenarios, some active messages could still be in the
Apps RX buffer which reduces the number of outstanding sleep messages.
Fix by accounting for NOACK messages while flushing sleep set requests
and ensuring that they are read before sending any sleep set requests.
The original changes were reverted to address issues with SMD transport.
This change includes fixes from earlier squashed into a single commit.

With zcache using zbud, strange locking scenarios are

Core 2 waiting on mapping->tree_lock which is taken by core 6
do_raw_spin_lock
raw_spin_lock_irq
atomic_cmpxchg
page_freeze_refs
__remove_mapping
shrink_page_list
Core 6 after taking mapping->tree_lock is waiting on zbud pool lock
which is held by core 5
zbud_alloc
zcache_store_page
__cleancache_put_page
cleancache_put_page
__delete_from_page_cache
spin_unlock_irq
__remove_mapping
shrink_page_list
shrink_inactive_list
Core 5 after taking zbud pool lock from zbud_free received an IRQ, and
after IRQ exit, softirqs were scheduled and end_page_writeback tried to
lock on mapping->tree_lock which is already held by Core 6. Deadlock.

This shows that allowing softirqs while holding zbud pool lock
can result in deadlocks. To fix this, 'commit 6a1fdaa36272
("mm: zbud: prevent softirq during zbud alloc, free and reclaim")'
decided to take spin_lock_bh during zbud_free, zbud_alloc and
zbud_reclaim. But this resulted in another deadlock.

zcache_store_page()
__cleancache_put_page()
__delete_from_page_cache()
__remove_mapping()
shrink_page_list()
Here, the spin_unlock_bh resulted in explicit invocation of do_sofirq,
which resulted in the acquisition of mapping->tree_lock which was already
taken by __remove_mapping.
The new fix considers the following facts.
1) zcache_store_page is always be called from __delete_from_page_cache
with mapping->tree_lock held and interrupts disabled. Thus zbud_alloc
which is called only from zcache_store_page is always called with
interrupts disabled.
2) zbud_free and zbud_reclaim_page can be called from zcache with or
without interrupts disabled. So an interrupt while holding zbud pool
lock can result in do_softirq and acquisition of mapping->tree_lock.
(1) implies zbud_alloc need not explicitly disable bh. But disable
interrupts to make sure zbud_alloc is safe with zcache, irrespective
of future changes. This will fix the second scenario.
(2) implies zbud_free and zbud_reclaim_page should use spin_lock_irqsave,
so that interrupts will not be triggered and inturn softirqs.
spin_lock_bh can't be used because a spin_unlock_bh can triger a softirq
even in interrupt context. This will fix the first scenario.

This deliberately changes the behavior of the per-cpuset
cpus file to not be effected by hotplug. When a cpu is offlined,
it will be removed from the cpuset/cpus file. When a cpu is onlined,
if the cpuset originally requested that that cpu was part of the cpuset, that
cpu will be restored to the cpuset. The cpus files still
have to be hierachical, but the ranges no longer have to be out of
the currently online cpus, just the physically present cpus.
