Merge tag 'asm-generic-nommu' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull nommu generic uaccess updates from Arnd Bergmann: "asm-generic: kill <asm/segment.h> and improve nommu generic uaccess helpers Christoph Hellwig writes: This is a series doing two somewhat interwinded things. It improves the asm-generic nommu uaccess helper to optionally be entirely generic and not require any arch helpers for the actual uaccess. For the generic uaccess.h to actually be generically useful I also had to kill off the mess we made of <asm/segment.h>, which really shouldn't exist on most architectures" * tag 'asm-generic-nommu' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: optimize generic uaccess for 8-byte loads and stores asm-generic: provide entirely generic nommu uaccess arch: mostly remove <asm/segment.h> asm-generic: don't include <asm/segment.h> from <asm/uaccess.h>
