Merge tag 'asm-generic-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
 "These are a number of unrelated cleanups, generally simplifying the
  architecture specific header files:

   - A series from Al Viro simplifies asm/vga.h, after it turns out that
     most of it can be generalized.

   - A series from Julian Vetter adds a common version of
     memcpy_{to,from}io() and memset_io() and changes most architectures
     to use that instead of their own implementation

   - A series from Niklas Schnelle concludes his work to make PC style
     inb()/outb() optional

   - Nicolas Pitre contributes improvements for the generic do_div()
     helper

   - Christoph Hellwig adds a generic version of page_to_phys() and
     phys_to_page(), replacing the slightly different architecture
     specific definitions.

   - Uwe Kleine-Koenig has a minor cleanup for ioctl definitions"
