  • 487722cf2   watchdog: Get rid of MODULE_ALIAS_MISCDEV statements ... Browse Code »

    I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
    and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

    Either the device is enumerated and the driver already has a module
    alias (e.g. PCI, USB etc.) that will get the right driver loaded
    automatically.

    Or the device is not enumerated and loading its driver will lead to
    more or less intrusive hardware poking. Such hardware poking should be
    limited to a bare minimum, so the user should really decide which
    drivers should be tried and in what order. Trying them all in
    arbitrary order can't do any good.

    On top of that, loading that many drivers at once bloats the kernel
    log. Also many drivers will stay loaded afterward, bloating the output
    of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
    loaded as a dependency) can't even be unloaded!

    If defining char-major-10-130 is needed then it should happen in
    user-space.

    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..
