The kernel sources, both unadulterated originals ('*.orig.tar.bz2') and
patched. Those patched with the 'bigphysarea' patch are '*.bphys.tar.bz2'.
Those patched with the atm patches are '*.atm.tar.bz2'. The atm-patched
kernels have also had the bigphysarea patch applied.

 The extension 'bz2' is the default extension for files compressed with
'bzip2'. This is a compressor that typically outperforms gzip by 10%,
which is significant here! You can unpack one of these source trees with
this command:

 cat filename.tar.bz2 | bzip2 -d -k | tar xf -

 Note that the original kernel sources, as downloaded from ftp.kernel.org,
unpack into the 'linux' subdirectory. I have unpacked each one and renamed
the top-level directory from 'linux' to 'linux-`uname -r`.orig' and then
repacked them.

 To be explicit with an example:

# cat linux-2.2.0.tar.bz2 | bzip2 -d -k | tar xf -
# mv linux linux-2.2.0.orig
# tar cf - linux-2.2.0.orig | bzip2 >linux-2.2.0.orig.tar.bz2
# rm -rf linux-2.2.0.orig


 This means that you can unpack all my kernel sources simultaneously
without them overwriting each other. Similarly, the patched kernels will
unpack into a directory name that matches the kernel version and the
applied patch.

 Sources which have been declared obsolete are in the 'deprecated'
subdirectory. They may disappear from there at any moment if disk space
becomes tight.
