++ The linux kernel is a kind of self-extracting executable.
++ Several compression algorithms are available, which differ
++ in efficiency, compression and decompression speed.
++ Compression speed is only relevant when building a kernel.
++ Decompression speed is relevant at each boot.
++
++ If you have any problems with bzip2 or lzma compressed
++ kernels, mail me (Alain Knaff) <alain@knaff.lu>. (An older
++ version of this functionality (bzip2 only), for 2.4, was
++ supplied by Christian Ludwig)
++
++ High compression options are mostly useful for users, who
++ are low on disk space (embedded systems), but for whom ram
++ size matters less.
++
++ If in doubt, select 'gzip'
++
++config KERNEL_GZIP

++ help
++ The old and tried gzip compression. Its compression ratio is
++ the poorest among the 3 choices; however its speed (both
++ compression and decompression) is the fastest.
++

++ bool "Bzip2"
++ help
++ Its compression ratio and speed is intermediate.
++ Decompression speed is slowest among the 3.
++ The kernel size is about 10 per cent smaller with bzip2,
++ in comparison to gzip.
++ Bzip2 uses a large amount of memory. For modern kernels
++ you will need at least 8MB RAM or more for booting.
++

++ Size and speed optimizations by Manuel Novoa III (mjn3@codepoet.org).
++
++ More efficient reading of Huffman codes, a streamlined read_bunzip()
++ function, and various other tweaks. In (limited) tests, approximately
++ 20% faster than bzcat on x86 and about 10% faster on arm.
++
++ Note that about 2/3 of the time is spent in read_unzip() reversing
++ the Burrows-Wheeler transformation. Much of that time is delay
++ resulting from cache misses.
