57b30ae7 ("workqueue: reimplement cancel_delayed_work() using
try_to_grab_pending()") made cancel_delayed_work() always return %true
unless someone else is also trying to cancel the work item, which is
broken - if the target work item is idle, the return value should be
%false.

try_to_grab_pending() indicates that the target work item was idle by
zero return value.  Use it for return.  Note that this brings
cancel_delayed_work() in line with __cancel_work_timer() in return
value handling.

Profile replacement can cause long chains of profiles to build up when
the profile being replaced is pinned. When the pinned profile is finally
freed, it puts the reference to its replacement, which may in turn nest
another call to free_profile on the stack. Because this may happen for
each profile in the replacedby chain this can result in a recusion that
causes the stack to overflow.

Break this nesting by directly walking the chain of replacedby profiles
(ie. use iteration instead of recursion to free the list). This results
in at most 2 levels of free_profile being called, while freeing a
replacedby chain.

If none of the elements in scrubrates[] matches, this loop will cause
__amd64_set_scrub_rate() to incorrectly use the n+1th element.

As the function is designed to use the final scrubrates[] element in the
case of no match, we can fix this bug by simply terminating the array
search at the n-1th element.

Boris: this code is fragile anyway, see here why:

The tile tool chain uses the .eh_frame information for backtracing.
The vmlinux build drops any .eh_frame sections at link time, but when
present in kernel modules, it causes a module load failure due to the
presence of unsupported pc-relative relocations.  When compiling to
use compiler feedback support, the compiler by default omits .eh_frame
information, so we don't see this problem.  But when not using feedback,
we need to explicitly suppress the .eh_frame.

[Originally sent by Ulf as two changes, squashed down into one with a
redone changelog, thanks to Russell King for analysis. -- broonie]

This reverts commit 688723 (spi/pl022: enable runtime PM) and commit
2fb30d (spi/pl022: fix spi-pl022 pm enable at probe).

Commit "spi/pl022: enable runtime PM" introduced runtime PM issues as it
interacted badly with the work Russell King had done to move core
runtime PM handling into the bus.  Due to that commit, "spi/pl022: fix
spi-pl022 pm enable at probe" was merged to fix part of those issues.

Instead of adding another fix, let's clean up and revert everything
back to when it was already fine.

The irqdomain semantics were supposed to be such that a linear
domain would be used if the passed first_irq was zero or
negative, but I got it wrong so only passing zero as first_irq
will work properly. Well, zero is NO_IRQ these days so let's
pass zero. The semantics of irqdomain_add_simple() will be

Since in the DT case, the linear domain path will not allocate
descriptors for the IRQs, we need to use irq_create_mapping()
for mapping hwirqs to Linux IRQs, so these descriptors get
created on-the-fly in this case.

ChangeLog v1->v2:

- Just use irq_create_mapping() in the .to_irq function since
  this is called before unmasking or enabling any interrupt
  lines, so irq_find_mapping() should be sufficient for the
  IRQ handler function.
