  • Currently users of mm.h need to include to use the macros
    malloc() and free() provided by mm.h. This fixes it.

  • set_error_fn() has become a useless complication after c1e7c3ae59
    ("bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure") fixed
    the use of error() in malloc(). Only decompress_unlzma.c had some use for
    it and that was easy to change too.

    This also gets rid of the static function pointer "error", which
    should have been marked as __initdata.

  • Fix checkstack error:

    lib/decompress_bunzip2.c: In function `get_next_block':
    lib/decompress_bunzip2.c:511: warning: the frame size of 1932 bytes is larger than 1024 bytes

    byteCount, symToByte, and mtfSymbol cannot be declared static or allocated
    dynamically so place them in the bunzip_data struct.

  • These includes were added by 079effb6933f34b9b1b67b08bd4fd7fb672d16ef
    ("kmemtrace, kbuild: fix slab.h dependency problem in
    lib/decompress_inflate.c") to fix the build when using kmemtrace. However
    this is not necessary when used to create a compressed kernel, and
    actually creates issues (brings a lot of things unavailable in the
    decompression environment), so don't include it if STATIC is defined.

  • decompress_bunzip2 and decompress_unlzma have a nasty hack that subtracts
    4 from the input length if being called in the pre-boot environment.

    This is a nasty hack because it relies on the fact that flush = NULL only
    when called from the pre-boot environment (i.e.
    arch/x86/boot/compressed/misc.c). initramfs.c/do_mounts_rd.c pass in a
    flush buffer (flush != NULL).

    This hack prevents the decompressors from being used with flush = NULL by
    other callers unless knowledge of the hack is propagated to them.

    This patch removes the hack by making decompress (called only from the
    pre-boot environment) a wrapper function that subtracts 4 from the input
    length before calling the decompressor.

  • Impact: cleanup

    lib/decompress_bunzip2.c depends on slab.h without including it:

    CC lib/decompress_bunzip2.o
    lib/decompress_bunzip2.c: In function ‘start_bunzip’:
    lib/decompress_bunzip2.c:636: error: implicit declaration of function ‘kmalloc’
    lib/decompress_bunzip2.c:636: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c: In function ‘bunzip2’:
    lib/decompress_bunzip2.c:682: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c:693: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c:726: error: implicit declaration of function ‘kfree’
    make[1]: *** [lib/decompress_bunzip2.o] Error 1
    make: *** [lib/] Error 2

    It gets included implicitly currently - but this will not be the
    case with upcoming kmemtrace changes.

  • Impact: Replaces inflate.c with a wrapper around zlib_inflate; new library code

    This is the first part of the bzip2/lzma patch

    The bzip patch is based on an idea by Christian Ludwig, includes support for
    compressing the kernel with bzip2 or lzma rather than gzip. Both
    compressors give smaller sizes than gzip. Lzma's decompresses faster
    than bzip2.

    It also supports ramdisks and initramfs' compressed using these two
    compressors.

    The functionality has been successfully used for a couple of years by
    the udpcast project

    This version applies to "tip" kernel 2.6.28

    This part contains:
    - changed inflate.c to accomodate rest of patch
    - implementation of bzip2 compression (not used at this stage yet)
    - implementation of lzma compression (not used at this stage yet)
    - Makefile routines to support bzip2 and lzma kernel compression
