    Subject[PATCH 00/11] jump label v7
    Hi,

    Based on David Miller's suggestion this version re-works the architecture
    interfaces for jump labels. I have also added a documentation file, and
    re-freshed the patchset against the latest -tip tree.

    The new architecture interface (quoting from the docs file), is as follows:

    "
    4) architecture interface

    There are a few functions and macros which arches must implement in order to
    take advantage of this optimization. As previously mentioned, if there is no
    architecture support we simply fall back to a traditional, load, test, and
    jump sequence.

    * add "HAVE_ARCH_JUMP_LABEL" to arch/<arch>/Kconfig to indicate support

    * #define JUMP_LABEL_NOP_SIZE, arch/x86/include/asm/jump_label.h

    * #define "JUMP_LABEL(tag, label, cond)", arch/x86/include/asm/jump_label.h

    * add: void arch_jump_label_transform(struct jump_entry *entry, enum jump_label_type type)
    and
    const u8 *arch_get_jump_label_nop(void)

    see: arch/x86/kernel/jump_label.c

    * finally add a definition for "struct jump_entry". This must be done in a
    separate .h file, b/c the modpost.c code uses this definition to sort the
    the jump label tabel in the vmlinux, so that it does not have to be sorted at
    runtime. see: arch/x86/include/asm/jump_entry.h
    "

    David, I re-worked the sparc64 to match the updated interfaces. The code should
    hopefully compile now, although I did not test the sparc bits.

    thanks,

    -Jason
