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" * tag 'asm-generic-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (24 commits) empty include/asm-generic/vga.h sparc: get rid of asm/vga.h asm/vga.h: don't bother with scr_mem{cpy,move}v() unless we need to vt_buffer.h: get rid of dead code in default scr_...() instances tty: serial: export serial_8250_warn_need_ioport lib/iomem_copy: fix kerneldoc format style hexagon: simplify asm/io.h for !HAS_IOPORT loongarch: Use new fallback IO memcpy/memset csky: Use new fallback IO memcpy/memset arm64: Use new fallback IO memcpy/memset New implementation for IO memcpy and IO memset watchdog: Add HAS_IOPORT dependency for SBC8360 and SBC7240 __arch_xprod64(): make __always_inline when optimizing for performance ARM: div64: improve __arch_xprod_64() asm-generic/div64: optimize/simplify __div64_const32() lib/math/test_div64: add some edge cases relevant to __div64_const32() asm-generic: add an optional pfn_valid check to page_to_phys asm-generic: provide generic page_to_phys and phys_to_page implementations asm-generic/io.h: Remove I/O port accessors for HAS_IOPORT=n tty: serial: handle HAS_IOPORT dependencies ...
