Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King: "A few ARM fixes: - fix a crash while performing TLB maintanence on early ARM SMP cores - blacklist Scorpion CPUs for hardware breakpoints - ARMs asm/types.h has been included as part of the UAPI due to the way the makefiles work, move it to uapi/asm/types.h to make it official - fix up ftrace syscall name matching" * 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8613/1: Fix the uaccess crash on PB11MPCore MAINTAINERS: update rmk's entries ARM: put types.h in uapi ARM: 8634/1: hw_breakpoint: blacklist Scorpion CPUs ARM: 8632/1: ftrace: fix syscall name matching
