    Pull "Disintegrate and delete asm/system.h" from David Howells:
    "Here are a bunch of patches to disintegrate asm/system.h into a set of
    separate bits to relieve the problem of circular inclusion
    dependencies.

    I've built all the working defconfigs from all the arches that I can
    and made sure that they don't break.

    The reason for these patches is that I recently encountered a circular
    dependency problem that came about when I produced some patches to
    optimise get_order() by rewriting it to use ilog2().

    This uses bitops - and on the SH arch asm/bitops.h drags in
    asm-generic/get_order.h by a circuituous route involving asm/system.h.

    The main difficulty seems to be asm/system.h. It holds a number of
    low level bits with no/few dependencies that are commonly used (eg.
    memory barriers) and a number of bits with more dependencies that
    aren't used in many places (eg. switch_to()).

    These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

    Move memory barriers here. This already done for MIPS and Alpha.

    (2) asm/switch_to.h

    Move switch_to() and related stuff here.

    (3) asm/exec.h

    Move arch_align_stack() here. Other process execution related bits
    could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

    Move xchg() and cmpxchg() here as they're full word atomic ops and
    frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

    Move die() and related bits.

    (6) asm/auxvec.h

    Move AT_VECTOR_SIZE_ARCH here.

    Other arch headers are created as needed on a per-arch basis."

    Fixed up some conflicts from other header file cleanups and moving code
    around that has happened in the meantime, so David's testing is somewhat
    weakened by that. We'll find out anything that got broken and fix it..

    Remove all #inclusions of asm/system.h preparatory to splitting and killing
    it. Performed with the following command:

    perl -p -i -e 's!^#\s*include\s*.*\n!!' `grep -Irl '^#\s*include\s*' *`

  • 63bad1452   [WATCHDOG] w83697ug: add error checking ... Browse Code »

    I noticed the W83697UG driver tries to register a watchdog even though
    it already noticed the chip isn't there.

    WDT driver for the Winbond(TM) W83697UG/UF Super I/O chip initialising.
    w83697ug/uf WDT: No W83697UG/UF could be found
    w83697ug/uf WDT: Watchdog already running. Resetting timeout to 60 sec
    w83697ug/uf WDT: cannot register miscdev on minor=130 (err=-16)

    Patch propagates the error back to wdt_init().

  • 7d8b09066   [WATCHDOG] Add driver for winbond w83697ug/uf watchdog feature ... Browse Code »

    Adapted the w83627hf_wdt.c driver to work with the w83697ug/uf chip,
    found on MSI Fuzzy CX700 boards.

    The method used is taken directly from the winbond datasheet and
    surprisingly it differs slightly from all the other winbond watchdogs.

    So far it has only been tested on the CX700 board that I have, but it
    seems to work nicely.
