On OCTEON the function is non-trivial and we can potentially even save
some memory.

e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

a669efc4a3 MIPS: Add hook to get C0 performance counter interrupt
The hardware perf event driver and oprofile interpret the global
cp0_perfcount_irq differently: in the hardware perf event driver
it is an offset from MIPS_CPU_IRQ_BASE and in oprofile it is the
actual IRQ number.  This still works most of the time since
MIPS_CPU_IRQ_BASE is usually 0, but is clearly wrong.  Since the
performance counter interrupt may vary from platform to platform
like the C0 timer interrupt, add the optional get_c0_perfcount_int
hook which returns the IRQ number of the performance counter.
The hook should return < 0 if the performance counter interrupt is
shared with the timer.  If the hook is not present, the CPU vector
reported in C0_IntCtl (cp0_perfcount_irq) is used.

078a55fc82 MIPS: Delete __cpuinit/__CPUINIT usage from MIPS code
commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit  -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings.  In any case, they are temporary and harmless.

Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
from asm files.  MIPS is interesting in this respect, because there
are also uasm users hiding behind their own renamed versions of the
__cpuinit macros.

e51066824a Merge branch 'devm_no_resource_check' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull devm usage cleanup from Wolfram Sang:
 "Lately, I have been experimenting how to improve the devm interface to
  make writing device drivers easier and less error prone while also
  getting rid of its subtle issues.  I think it has more potential but
  still needs work and definately conistency, especiall in its usage.

  The first thing I come up with is a low hanging fruit regarding
  devm_ioremap_resouce().  This function already checks if the passed
  resource is valid and gives an error message if not.  So, we can
  remove similar checks from the drivers and get rid of a bit of code
  and a number of inconsistent error strings.

  This series only removes the unneeded check iff devm_ioremap_resource
  follows platform_get_resource directly.  The previous version tried to
  shuffle code if needed, too, what lead to an embarrasing bug.  It
  turned out to me that shuffling code for all cases found will make the
  automated script too complex, so I am unsure if an automated cleanup
  is the proper tool for this case.  Removing the easy stuff seems
  worthwhile to me, though.

  Despite various architectures and platform dependencies, I managed to
  compile test 45 out of 57 modified files locally using heuristics and
  defconfigs."
