Hello Russell,

The following changes since commit 73a09d212ec65b7068a283e6034fa05649d3d075:

  Merge branch 'for-next' of git://git.pengutronix.de/git/ukl/linux into devel-stable (2013-03-09 15:49:32 +0000)

  ARM: ARMv7-M: implement read_cpuid_ext (2013-05-17 11:44:40 +0200)

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.

Best regards
Uwe
