Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Three fixes this time around:
- ensure sparse realises that we're building for a 32-bit arch on
64-bit hosts.
- use the correct instruction for semihosting on v7m (nommu) CPUs.
- reserve address 0 to prevent the first page of memory being used on
nommu systems"
* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: 8704/1: semihosting: use proper instruction on v7m processors
ARM: 8701/1: fix sparse flags for build on 64bit machines
ARM: 8700/1: nommu: always reserve address 0 away
