Pull late MIPS fixes from Ralf Baechle:
"This fixes a number of lose ends in the MIPS code and various bug
fixes.
Aside of dropping some patch that should not be in this pull request
everything has sat in -next for quite a while and there are no known
issues.
The biggest patch in this patch set moves the allocation of an array
that is aliased to a function (for runtime generated code) to
assembler code. This avoids an issue with certain toolchains when
building for microMIPS."
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (35 commits)
MIPS: PCI: Move fixups from __init to __devinit.
MIPS: Fix bug.h MIPS build regression
MIPS: sync-r4k: remove redundant irq operation
MIPS: smp: Warn on too early irq enable
MIPS: call set_cpu_online() on cpu being brought up with irq disabled
MIPS: call ->smp_finish() a little late
MIPS: Yosemite: delay irq enable to ->smp_finish()
MIPS: SMTC: delay irq enable to ->smp_finish()
MIPS: BMIPS: delay irq enable to ->smp_finish()
MIPS: Octeon: delay enable irq to ->smp_finish()
MIPS: Oprofile: Fix build as a module.
MIPS: BCM63XX: Fix BCM6368 IPSec clock bit
MIPS: perf: Fix build error caused by unused counters_per_cpu_to_total()
MIPS: Fix Magic SysRq L kernel crash.
MIPS: BMIPS: Fix duplicate header inclusion.
mips: mark const init data with __initconst instead of __initdata
MIPS: cmpxchg.h: Add missing include
MIPS: Malta may also be equipped with MIPS64 R2 processors.
MIPS: Fix typo multipy -> multiply
MIPS: Cavium: Fix duplicate ARCH_SPARSEMEM_ENABLE in kconfig.
...
Fixups are executed once the pci-device is found which is during boot
process so __init seems fine as long as the platform does not support
hotplug.
However it is possible to remove the PCI bus at run time and have it
rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call
the fixups again.
