  • 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)

    Keep the result holder variable the same type as the quantity we are
    retreiving in the get_user() macro - don't go through a pointer version
    of the user space address type.

    Using the address type causes problems if the address type was const
    (newer versions of gcc quite rightly error out for that condition).

  • 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().

  • 908dcecda   [PATCH] adjust handle_IRR_event() return type ... Browse Code »

    Correct the return type of handle_IRQ_event() (inconsistency noticed during
    Xen development), and remove redundant declarations. The return type
    adjustment required breaking out the definition of irqreturn_t into a
    separate header, in order to satisfy current include order dependencies.

  • 67b0ad574   [PATCH] bitops: use non atomic operations for minix_*_bit() and ext2_*_bit() ... Browse Code »

    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.

    We're starting a number of big applications (memory footprint app.
    1MByte) on our Arcturus uC5272. Therefore memory fragmentation is a
    real pain for us. We've switched to uClinux-2.4.27-uc1 and found that
    page_alloc2 fragments the memory heavily.

    Digging into it we found a bug in the find_next_zero_bit function in the
    m68knommu/bitops.h file. if the size isn't a multiple of 32 than the
    upper bits of the last word to be searched should be masked. But the
    functions masks the lower bits of the last word because it uses a right
    shift instead of a left shift operator.

  • 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.
