  • 52393ccc0   [PATCH] remove set_wmb - arch removal ... Browse Code »

    set_wmb should not be used in the kernel because it just confuses the
    code more and has no benefit. Since it is not currently used in the
    kernel this patch removes it so that new code does not include it.

    All archs define set_wmb(var, value) to do { var = value; wmb(); }
    while(0) except ia64 and sparc which use a mb() instead. But this is
    still moot since it is not used anyway.

    Hasn't been tested on any archs but x86 and x86_64 (and only compiled
    tested)

  • f6dc8c5b8   [PATCH] Make cpu_relax() imply barrier() on all arches ... Browse Code »

    During the recent discussion of taking 'volatile' off of the spinlock, I
    noticed that while most arches #define cpu_relax() such that it implies
    barrier(), some arches define cpu_relax() to be empty.

    This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
    sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

    __NR_sys_kexec_load should be __NR_kexec_load. Mainly affects users of the

  • 22a9835c3   [PATCH] unify PFN_* macros ... Browse Code »

    Just about every architecture defines some macros to do operations on pfns.
    They're all virtually identical. This patch consolidates all of them.

    One minor glitch is that at least i386 uses them in a very skeletal header
    file. To keep away from #include dependency hell, I stuck the new
    definitions in a new, isolated header.

    Of all of the implementations, sh64 is the only one that varied by a bit.
    It used some masks to ensure that any sign-extension got ripped away before
    the arithmetic is done. This has been posted to that sh64 maintainers and
    the development list.

    Compiles on x86, x86_64, ia64 and ppc64.

    Bitmap functions for the minix filesystem and the ext2 filesystem except
    ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic
    guarantees.

    But these are defined by using atomic bit operations on several architectures.
    (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc,
    sparc64, v850, and xtensa)

    This patch switches to non atomic bit operation.

  • f348d70a3   [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notifications ... Browse Code »

    Implement the half-closed devices notifiation, by adding a new POLLRDHUP
    (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the
    existing POLLHUP handling, that does not report correctly half-closed
    devices, was feared to be changed, this implementation leaves the current
    POLLHUP reporting unchanged and simply add a new bit that is set in the few
    places where it makes sense. The same thing was discussed and conceptually
    agreed quite some time ago:

    http://lkml.org/lkml/2003/7/12/116

    Since this new event bit is added to the existing Linux poll infrastruture,
    even the existing poll/select system calls will be able to use it. As far
    as the existing POLLHUP handling, the patch leaves it as is. The
    pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing
    archs and sets the bit in the six relevant files. The other attached diff
    is the simple change required to sys/epoll.h to add the EPOLLRDHUP
    definition.

    There is "a stupid program" to test POLLRDHUP delivery here:

    http://www.xmailserver.org/pollrdhup-test.c

    It tests poll(2), but since the delivery is same epoll(2) will work equally.

  • f8aaeacec   [PATCH] consolidate asm/futex.h ... Browse Code »

    Most of the architectures have the same asm/futex.h. This consolidates them
    into asm-generic, with the arches including it from their own asm/futex.h.

    In the case of UML, this reverts the old broken futex.h and goes back to using
    the same one as almost everyone else.

  • d3cb48714   [PATCH] atomic_long_t & include/asm-generic/atomic.h V2 ... Browse Code »

    Several counters already have the need to use 64 atomic variables on 64 bit
    platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall
    back to 32 bit atomic on 32 bit platforms.

    The VM statistics patch that I am working on will also make more extensive
    use of atomic64.

    This patch introduces a new type atomic_long_t by providing definitions in
    asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits
    on 32 bit platforms and 64 bits on 64 bit platforms.

    Also cleans up the determination of the mm_counter_t in sched.h.

    This patch removes page_pte_prot and page_pte macros from all

    and others none. These macros are not used anywhere.

    page_pte_prot(page, prot) is identical to mk_pte(page, prot) and
    page_pte(page) is identical to page_pte_prot(page, __pgprot(0)).

    * The following architectures define both page_pte_prot and page_pte

    arm, arm26, ia64, sh64, sparc, sparc64

    * The following architectures define only page_pte (broken)

    frv, i386, m32r, mips, sh, x86-64

    * All other architectures define neither

  • 676067cfe   [PATCH] Remove unused var from asm/futex.h ... Browse Code »

    As recently done by Russell King for ARM, commit
    4732efbeb997189d9f9b04708dc26bf8613ed721 introduces a generic asm/futex.h copied
    along most arches, which includes a "-ENOSYS support" to be changed if needed.
    However, it includes an unused var (taken from the "real" version) which GCC
    warns about.

    Remove it from all arches having that file version (i.e. same GIT id).
    $ git-diff-tree -r HEAD
    and
    $ git-ls-tree -r HEAD include/|grep 9feff4ce1424bc390608326240be369eb13aa648

    may be more interesting than looking at the patch itself, to make sure I've
    just copied the arm header to all other archs having the original dummy version
    of this file.
