  • b8fa05719   Revert "lib: build list_sort() only if needed" ... Browse Code »

    This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504.

    It turns ou that not only was it missing a case (XFS) that needed it,
    but perhaps more importantly, people sometimes want to enable new
    modules that they hadn't had enabled before, and if such a module uses
    list_sort(), it can't easily be inserted any more.

    So rather than add a "select LIST_SORT" to the XFS case, just leave it
    compiled in. It's not all _that_ big, after all, and the inconvenience
    isn't worth it.

  • 09d4e0edd   lib: Provide generic atomic64_t implementation ... Browse Code »

    Many processor architectures have no 64-bit atomic instructions, but
    we need atomic64_t in order to support the perf_counter subsystem.

    This adds an implementation of 64-bit atomic operations using hashed
    spinlocks to provide atomicity. For each atomic operation, the address
    of the atomic64_t variable is hashed to an index into an array of 16
    spinlocks. That spinlock is taken (with interrupts disabled) around the
    operation, which can then be coded non-atomically within the lock.

    On UP, all the spinlock manipulation goes away and we simply disable
    interrupts around each operation. In fact gcc eliminates the whole
    atomic64_lock variable as well.

  • 69c35efcf   libcrc32c: Move implementation to crypto crc32c ... Browse Code »

    This patch swaps the role of libcrc32c and crc32c. Previously
    the implementation was in libcrc32c and crc32c was a wrapper.
    Now the code is in crc32c and libcrc32c just calls the crypto
    layer.

    The reason for the change is to tap into the algorithm selection
    capability of the crypto API so that optimised implementations
    such as the one utilising Intel's CRC32C instruction can be
    used where available.

  • 9ba16087d   Kconfig: eliminate "def_bool n" constructs ... Browse Code »

    Using "def_bool n" is pointless, simply using bool here appears more
    appropriate.

    Further, retaining such options that don't have a prompt and aren't
    selected by anything seems also at least questionable.

  • 19870def5   x86, bitops: select the generic bitmap search functions ... Browse Code »

    Introduce GENERIC_FIND_FIRST_BIT and GENERIC_FIND_NEXT_BIT in
    lib/Kconfig, defaulting to off. An arch that wants to use the
    generic implementation now only has to use a select statement
    to include them.

    I added an always-y option (X86_CPU) to arch/x86/Kconfig.cpu
    and used that to select the generic search functions. This
    way ARCH=um SUBARCH=i386 automatically picks up the change
    too, and arch/um/Kconfig.i386 can therefore be simplified a
    bit. ARCH=um SUBARCH=x86_64 does things differently, but
    still compiles fine. It seems that a "def_bool y" always
    wins over a "def_bool n"?

    This is a hybrid version of the patch to add the LZO1X compression
    algorithm to the kernel. Nitin and myself have merged the best parts of
    the various patches to form this version which we're both happy with (and
    are jointly signing off).

    The performance of this version is equivalent to the original minilzo code
    it was based on. Bytecode comparisons have also been made on ARM, i386 and
    x86_64 with favourable results.

    There are several users of LZO lined up including jffs2, crypto and reiser4
    since its much faster than zlib.

  • 411f0f3ed   Introduce CONFIG_HAS_DMA ... Browse Code »

    Architectures that don't support DMA can say so by adding a config NO_DMA
    to their Kconfig file. This will prevent compilation of some dma specific
    driver code. Also dma-mapping-broken.h isn't needed anymore on at least
    s390. This avoids compilation and linking of otherwise dead/broken code.

    Other architectures that include dma-mapping-broken.h are arm26, h8300,
    m68k, m68knommu and v850. If these could be converted as well we could get
    rid of the header file.
