Merge branch 'fixes-for-3.9-latest' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull second round of PARISC updates from Helge Deller: "The most important fix in this branch is the switch of io_setup, io_getevents and io_submit syscalls to use the available compat syscalls when running 32bit userspace on 64bit kernel. Other than that it's mostly removal of compile warnings." * 'fixes-for-3.9-latest' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: fix redefinition of SET_PERSONALITY parisc: do not install modules when installing kernel parisc: fix compile warnings triggered by atomic_sub(sizeof(),v) parisc: check return value of down_interruptible() in hp_sdc_rtc.c parisc: avoid unitialized variable warning in pa_memcpy() parisc: remove unused variable 'compat_val' parisc: switch to compat_functions of io_setup, io_getevents and io_submit parisc: select ARCH_WANT_FRAME_POINTERS
