Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "A number of smallish fixes scattered around the ARM code. Probably the most serious one is the one from Al addressing the missing locking in the swap emulation code." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7607/1: realview: fix private peripheral memory base for EB rev. B boards ARM: 7606/1: cache: flush to LoUU instead of LoUIS on uniprocessor CPUs ARM: missing ->mmap_sem around find_vma() in swp_emulate.c ARM: 7605/1: vmlinux.lds: Move .notes section next to the rodata ARM: 7602/1: Pass real "__machine_arch_type" variable to setup_machine_tags() procedure ARM: 7600/1: include CONFIG_DEBUG_LL_INCLUDE rather than mach/debug-macro.S
