      "message": "lib: add support for LZO-compressed kernels\n\nThis patch series adds generic support for creating and extracting\nLZO-compressed kernel images, as well as support for using such images on\nthe x86 and ARM architectures, and support for creating and using\nLZO-compressed initrd and initramfs images.\n\nRussell King said:\n\n: Testing on a Cortex A9 model:\n: - lzo decompressor is 65% of the time gzip takes to decompress a kernel\n: - lzo kernel is 9% larger than a gzip kernel\n:\n: which I\u0027m happy to say confirms your figures when comparing the two.\n:\n: However, when comparing your new gzip code to the old gzip code:\n: - new is 99% of the size of the old code\n: - new takes 42% of the time to decompress than the old code\n:\n: What this means is that for a proper comparison, the results get even better:\n: - lzo is 7.5% larger than the old gzip\u0027d kernel image\n: - lzo takes 28% of the time that the old gzip code took\n:\n: So the expense seems definitely worth the effort.  The only reason I\n: can think of ever using gzip would be if you needed the additional\n: compression (eg, because you have limited flash to store the image.)\n:\n: I would argue that the default for ARM should therefore be LZO.\n\nThis patch:\n\nThe lzo compressor is worse than gzip at compression, but faster at\nextraction.  Here are some figures for an ARM board I\u0027m working on:\n\nUncompressed size: 3.24Mo\ngzip  1.61Mo 0.72s\nlzo   1.75Mo 0.48s\n\nSo for a compression ratio that is still relatively close to gzip, it\u0027s\nmuch faster to extract, at least in that case.\n\nThis part contains:\n - Makefile routine to support lzo compression\n - Fixes to the existing lzo compressor so that it can be used in\n   compressed kernels\n - wrapper around the existing lzo1x_decompress, as it only extracts one\n   block at a time, while we need to extract a whole file here\n - config dialog for kernel compression\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: cleanup]\nSigned-off-by: Albin Tonnerre \u003calbin.tonnerre@free-electrons.com\u003e\nTested-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nAcked-by: \"H.
