Merge branch 'parisc-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc update from Helge Deller: - a bugfix for sticon (parisc text console driver) to not crash the 64bit kernel on machines with more than 4GB RAM - added kernel audit support - made udelay() implementation SMP-safe - "make install" now does not depend on vmlinux - added defconfigs for 32- and 64-kernels * 'parisc-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: add generic 32- and 64-bit defconfigs parisc: sticon - unbreak on 64bit kernel parisc: signal fixup - SIGBUS vs. SIGSEGV parisc: implement full version of access_ok() parisc: correctly display number of active CPUs parisc: do not count IPI calls twice parisc: make udelay() SMP-safe parisc: remove duplicate define parisc: make "make install" not depend on vmlinux parisc: add kernel audit feature parisc: provide macro to create exception table entries
