Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
A few more things this time around. The only thing warranting some
commentry is the modpost change, which allows folk building a Thumb2
enabled kernel to see section mismatch warnings. This is why many
weren't noticed with OMAP.
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM/audit: include audit header and fix audit arch
ARM: OMAP: fix voltage domain build errors with PM_OPP disabled
ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency'
ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised
ARM: 7327/1: need to include asm/system.h in asm/processor.h
ARM: 7326/2: PL330: fix null pointer dereference in pl330_chan_ctrl()
ARM: 7164/3: PL330: Fix the size of the dst_cache_ctrl field
ARM: 7325/1: fix v7 boot with lockdep enabled
ARM: 7324/1: modpost: Fix section warnings for ARM for many compilers
ARM: 7323/1: Do not allow ARM_LPAE on pre-ARMv7 architectures
