    bzip2/lzma: library support for gzip, bzip2 and lzma decompression · bc22c17e

    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
