Merge branch 'parisc-4.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull two parisc fixes from Helge Deller: "One fix to avoid usage of BITS_PER_LONG in user-space exported swab.h header which breaks compiling qemu, and one trivial fix for printk continuation in the parisc parport driver" * 'parisc-4.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Don't use BITS_PER_LONG in userspace-exported swab.h header parisc, parport_gsc: Fixes for printk continuation lines
