If the lzma/gzip decompressors are called with insufficient input data
(len > 0 & fill = NULL), they will attempt to call the fill function to
obtain more data, leading to a kernel oops.Signed-off-by: Phillip Lougher

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.Signed-off-by: Albin Tonnerre

Fix and improve comments in decompress/generic.h that describe the
decompressor API. Also remove an unused definition, and rename INBUF_LEN
in lib/decompress_inflate.c to conform to bzip2/lzma naming.Signed-off-by: Phillip Lougher

Impact: fix build
lib/decompress_inflate.c depends on slab.h without including it:

Impact: Bug fix
Fix gunzip uncompression, so that it also works with files with
embedded filenames that are larger than one block.Signed-off-by: Alain Knaff

Impact: Cleanup
Fix constant 0x8100 /* 32K */; according to Alain the value 0x8100 was
left over test code to test misalignment, the correct value is indeed
0x8000 == 32K.Signed-off-by: H. Peter Anvin

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 projectThis 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 compressionSigned-off-by: Alain Knaff
