  • 148817ba0   asm-generic: add another generic ext2 atomic bitops ... Browse Code »

    The majority of architectures implement ext2 atomic bitops as
    test_and_{set,clear}_bit() without spinlock.

    This adds this type of generic implementation in ext2-atomic-setbit.h and
    use it wherever possible.

  • 61f2e7b0f   bitops: remove minix bitops from asm/bitops.h ... Browse Code »

    minix bit operations are only used by minix filesystem and useless by
    other modules. Because byte order of inode and block bitmaps is different
    on each architecture like below:

    m68k:
    big-endian 16bit indexed bitmaps

    h8300, microblaze, s390, sparc, m68knommu:
    big-endian 32 or 64bit indexed bitmaps

    m32r, mips, sh, xtensa:
    big-endian 32 or 64bit indexed bitmaps for big-endian mode
    little-endian bitmaps for little-endian mode

    Others:
    little-endian bitmaps

    In order to move minix bit operations from asm/bitops.h to architecture
    independent code in minix filesystem, this provides two config options.

    CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
    CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
    native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
    m32r, mips, sh, xtensa). The architectures which always use little-endian
    bitmaps do not select these options.

    Finally, we can remove minix bit operations from asm/bitops.h for all
    architectures.

  • f312eff81   bitops: remove ext2 non-atomic bitops from asm/bitops.h ... Browse Code »

    As the result of conversions, there are no users of ext2 non-atomic bit
    operations except for ext2 filesystem itself. Now we can put them into
    architecture independent code in ext2 filesystem, and remove from
    asm/bitops.h for all architectures.

  • 861b5ae7c   bitops: introduce little-endian bitops for most architectures ... Browse Code »

    Introduce little-endian bit operations to the big-endian architectures
    which do not have native little-endian bit operations and the
    little-endian architectures. (alpha, avr32, blackfin, cris, frv, h8300,
    ia64, m32r, mips, mn10300, parisc, sh, sparc, tile, x86, xtensa)

    These architectures can just include generic implementation
    (asm-generic/bitops/le.h).

  • 8d6f9af91   ia64: boolean __test_and_clear_bit ... Browse Code »

    __test_and_clear_bit() returns a bitfield with the tested-for bit set.
    Make it consistent with the other bitops - of ia64 but also every
    other architecture - and return a boolean value.

    After moving the the include files there were a few clean-ups:

    1) Some files used #include , changed to

    2) Some comments alerted maintainers to look at various header files to
    make matching updates if certain code were to be changed. Updated these
    comments to use the new include paths.

    3) Some header files mentioned their own names in initial comments. Just
    deleted these self references.
