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
