bzip2/lzma: move initrd/ramfs options out of BLK_DEV Impact: Partial resolution of build failure Move the initrd/initramfs configuration options from drivers/block/Kconfig to usr/Kconfig, since they do not and should not depend on CONFIG_BLK_DEV.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

decompressors: add boot-time XZ support This implements the API defined in <linux/decompress/generic.h> 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 <lasse.collin@tukaani.org> Cc: "H.

bzip2/lzma: make internal initramfs compression configurable Impact: Avoids silent environment dependency Make builtin initramfs compression an explicit configurable. The previous version would pick a compression based on the binaries which were installed on the system, which could lead to unexpected results. It is now explicitly configured, and not having the appropriate binaries installed on the build host is simply an error. Signed-off-by: Alain Knaff <alain@knaff.lu> Signed-off-by: H.
