Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha
Pull alpha updates from Matt Turner: "This pull adds the implementations of some Tru64 syscalls which allow some proprietary software such as the C compiler to work on Linux. Also, it adds some big-endian ioread functions to help us get closer to building allyesconfig." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha: alpha: add io{read,write}{16,32}be functions alpha: implement various OSF/1 stat syscalls alpha: implement setsysinfo(SSI_LMF) as a no-op
