Merge branch 'for-next' of git://git.pengutronix.de/git/ukl/linux into devel-stable
Pull ARM-v7M support from Uwe Kleine-König:
"All but the last patch were in next since next-20130418 without issues.
The last patch fixes a problem in combination with
8164f7a (ARM: 7680/1: Detect support for SDIV/UDIV from ISAR0 register)
which triggers a WARN_ON without an implemented read_cpuid_ext.
The branch merges fine into v3.10-rc1 and I'd be happy if you pulled it
for 3.11-rc1. The only missing piece to be able to run a Cortex-M3 is
the irqchip driver that will go in via Thomas Gleixner and platform
specific stuff."
