Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Three more fixes:
- Fix the previous fix merged in the last pull for the Thumb2
decompressor.
- A fix from Vladimir to correctly identify the V7M cache type.
- The optimised 3G vmsplit case does not work with LPAE, so don't
allow this to be selected for LPAE configurations"
* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: 8682/1: V7M: Set cacheid iff DminLine or IminLine is nonzero
ARM: 8681/1: make VMSPLIT_3G_OPT depends on !ARM_LPAE
ARM: 8680/1: boot/compressed: fix inappropriate Thumb2 mnemonic for __nop
