Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King: "Some further ARM fixes: - another build fix for the kprobes test code - a fix for no kuser helpers for the set_tls code, which oopsed on noMMU hardware - a fix for alignment handler with neon opcodes being misinterpreted - turning off the hardware access support, which is not implemented - a build fix for the v7 coherency exiting code, which can be built in non-v7 environments (but still only executed on v7 CPUs)" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8179/1: kprobes-test: Fix compile error "bad immediate value for offset" ARM: 8178/1: fix set_tls for !CONFIG_KUSER_HELPERS ARM: 8177/1: cacheflush: Fix v7_exit_coherency_flush exynos build breakage on ARMv6 ARM: 8165/1: alignment: don't break misaligned NEON load/store ARM: 8164/1: mm: clear SCTLR.HA instead of setting it for LPAE
