kbuild: Fix computing srcversion for modules

2011-03-13T22:59:58Z

Recent change to fixdep: commit b7bd182176960fdd139486cadb9962b39f8a2b50 Author: Michal Marek Date: Thu Feb 17 15:13:54 2011 +0100 fixdep: Do not record dependency on the source file itself changed the format of the *.cmd files without realizing that it is also used by modpost. Put the path to the source file to the file back, in a special variable, so that modpost sees all source files when calculating srcversion for modules.

fixdep: Do not record dependency on the source file itself

2011-02-21T12:35:17Z

The dependency is already expressed by the Makefiles, storing it in the .cmd file breaks build if a .c file is replaced by .S or vice versa, because the .cmd file contains foo/bar.o: foo/bar.c ... foo/bar.c ... : so the foo/bar.c -> foo/bar.o rule triggers even if there is no foo/bar.c anymore.

deb-pkg: Fix building outside of source tree (O=...).

2011-02-04T13:53:45Z

When building linux-headers package using deb-pkg, builddeb erroneously assume current directory is the source tree. This is not true if building in another directory, using make O=... deb-pkg. This patch fix this problem. Signed-off-by: Nicolas de Pesloüan Tested-by: Nikolai Kondrashov Acked-by: maximilian attems Signed-off-by: Michal Marek

decompressors: add boot-time XZ support

2011-01-13T16:03:25Z

This implements the API defined in which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by: Lasse Collin Cc: "H.

decompressors: add XZ decompressor module

2011-01-13T16:03:24Z

In userspace, the .lzma format has become mostly a legacy file format that got superseded by the .xz format. Similarly, LZMA Utils was superseded by XZ Utils. These patches add support for XZ decompression into the kernel. Most of the code is as is from XZ Embedded . It was written for the Linux kernel but is usable in other projects too. Advantages of XZ over the current LZMA code in the kernel: - Nice API that can be used by other kernel modules; it's not limited to kernel, initramfs, and initrd decompression. - Integrity check support (CRC32) - BCJ filters improve compression of executable code on certain architectures. These together with LZMA2 can produce a few percent smaller kernel or Squashfs images than plain LZMA without making the decompression slower. This patch: Add the main decompression code (xz_dec), testing module (xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool, and documentation. The xz_dec module is enough to have a usable XZ decompressor e.g. for Squashfs. Signed-off-by: Lasse Collin Cc: "H.
