  • dcd497f99   [PATCH] streamline preempt_count type across archs ... Browse Code »

    The preempt_count member of struct thread_info is currently either defined
    as int, unsigned int or __s32 depending on arch. This patch makes the type
    of preempt_count an int on all archs.

    Having preempt_count be an unsigned type prevents the catching of
    preempt_count < 0 bugs, and using int on some archs and __s32 on others is
    not exactely "neat" - much nicer when it's just int all over.

    A previous version of this patch was already ACK'ed by Robert Love, and the
    only change in this version of the patch compared to the one he ACK'ed is
    that this one also makes sure the preempt_count member is consistently
    commented.

  • 39c715b71   [PATCH] smp_processor_id() cleanup ... Browse Code »

    This patch implements a number of smp_processor_id() cleanup ideas that
    Arjan van de Ven and I came up with.

    The previous __smp_processor_id/_smp_processor_id/smp_processor_id API
    spaghetti was hard to follow both on the implementational and on the
    usage side.

    Some of the complexity arose from picking wrong names, some of the
    complexity comes from the fact that not all architectures defined
    __smp_processor_id.

    In the new code, there are two externally visible symbols:

    - smp_processor_id(): debug variant.

    - raw_smp_processor_id(): nondebug variant. Replaces all existing
    uses of _smp_processor_id() and __smp_processor_id(). Defined
    by every SMP architecture in include/asm-*/smp.h.

    There is one new internal symbol, dependent on DEBUG_PREEMPT:

    - debug_smp_processor_id(): internal debug variant, mapped to
    smp_processor_id().

    Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new
    lib/smp_processor_id.c file. All related comments got updated and/or
    clarified.

    I have build/boot tested the following 8 .config combinations on x86:

    {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}

    I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other
    architectures are untested, but should work just fine.)

  • b1ecb4c3a   [PATCH] asm/signal.h unification ... Browse Code »

    New file - asm-generic/signal.h. Contains declarations of
    __sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default
    definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK.

    asm-*/signal.h switched to including it. The only exception is
    asm-parisc/signal.h that wants its own declaration of __sighandler_t;
    that one is left as-is.

    asm-ppc64/signal.h required one more thing - unlike everybody else it
    used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to
    common spelling.

  • a71c1ab50   [PATCH] consolidate SIGEV_PAD_SIZE ... Browse Code »

    Discussing with Matthew Wilcox some of his outstanding patches lead me to
    this patch (among others).

    The preamble in struct sigevent can be expressed independently of the
    architecture.

    Also use __ARCH_SI_PREAMBLE_SIZE on ia64.

  • 4750e2c0c   [PATCH] add EOWNERDEAD and ENOTRECOVERABLE version 2 ... Browse Code »

    Add EOWNERDEAD and ENOTRECOVERABLE to all architectures. This is to
    support the upcoming patches for robust mutexes.

    We normally don't reserve parts of the name/number space for external
    patches, but robust mutexes are sufficiently popular and important to
    justify it in this case.

  • 7f261b5f0   [PATCH] move SA_xxx defines to linux/signal.h ... Browse Code »

    The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE,
    SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to
    linux/signal.h. This looks like a left-over after the irq-handling code
    was consolidated. The code was moved to kernel/irq/*, but the flags are
    still left per-arch.

    Right now, adding a new IRQ flag to the arch-specific header, like this
    patch does:
    http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1
    no longer works, it breaks the compilation for all other arches, unless you
    add that flag to all the other arch-specific headers too. So I think such
    a clean-up makes sense.
