The first patch is exactly the patch (41750d31fc9599fd81763e685) from git repo: kernel/git/hpa/linux-earlyinitramfs. Ony the Makefile was slightly adjusted to latest Linus kernel (3.6.0-rc3). Because of the special requirements hpa mentioned, I gave up the cleaner callback approach. It may make sense to revive it if there are potential more users and let the very early code call the cpio decoder directly and let others use the callback interface I had made up. Anyway, it would be great to see these two patches showing up in a mainline branch and linux-next asap, so that they can slip in with the next (3.7) merge window. Working on ACPI features or debugging ACPI problems is a nightmare on Linux currently. ACPI table overrding via initrd makes working on such problems a lot easier. Thomas
