Subject: [PATCH 1/2] kbuild: Enable decompression for use by EXTRA_FIRMWARE The build system can currently only compress files. This patch adds the functionality to decompress files. Decompression is needed for building firmware files into the kernel if those files are compressed on the filesystem. Compressed firmware files are in use by Gentoo, Fedora, Arch, and others.
