Merge branch 'late-for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM update from Russell King: "This is the final round of stuff for ARM, left until the end of the merge window to reduce the number of conflicts. This set contains the ARM part of David Howells UAPI changes, and a fix to the ordering of 'select' statements in ARM Kconfig files (see the appropriate commit for why this happened - thanks to Andrew Morton for pointing out the problem.) I've left this as long as I dare for this window to avoid conflicts, and I regenerated the config patch yesterday, posting it to our mailing list for review and testing. I have several acks which include successful test reports for it. However, today I notice we've got new conflicts with previously unseen code... though that conflict should be trivial (it's my changes vs a one liner.)" * 'late-for-linus' of git://git.linaro.org/people/rmk/linux-arm: ARM: config: make sure that platforms are ordered by option string ARM: config: sort select statements alphanumerically UAPI: (Scripted) Disintegrate arch/arm/include/asm Fix up fairly conflict in arch/arm/Kconfig (the select re-organization vs recent addition of GENERIC_KERNEL_EXECVE)
