Merge branch 'parisc-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull two parisc fixes from Helge Deller: "The first patch ensures that the high-res cr16 clocksource (which was added in kernel 4.7) gets choosen as default clocksource for parisc. The second patch moves the #define of EREFUSED down inside errno.h and thus unbreaks building the gccgo compiler" * 'parisc-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Fix order of EREFUSED define in errno.h parisc: Fix automatic selection of cr16 clocksource
