Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM and clkdev fixes from Russell King:
"Two patches for clkdev which resolve the long standing issue that the
devm_* versions were dependent on clkdev, which they shouldn't have
been. Instead, they're dependent on HAVE_CLK instead, which implies
that you're providing clk_get() and clk_put().
A small fix to the ARM decompressor to ensure that the page tables are
properly interpreted by the CPU, and reserve syscall 378 for kcmp (the
checksyscalls.sh script is unfortunately currently broken so arch
maintainers aren't getting notified of new syscalls...)
Lastly, a larger fix for an issue between the common clk subsystem and
smp_twd which causes warnings to be spat out."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: reserve syscall 378 for kcmp
ARM: 7535/1: Reprogram smp_twd based on new common clk framework notifiers
ARM: 7537/1: clk: Fix release in devm_clk_put()
ARM: 7532/1: decompressor: reset SCTLR.TRE for VMSA ARMv7 cores
ARM: 7534/1: clk: Make the managed clk functions generically available
