Subject: Early cpio decoder and ACPI table override via initrd making use of it
Date: Fri, 21 Sep 2012 15:28:03 +0200 [thread overview]
Message-ID: <1348234085-39220-1-git-send-email-trenn@suse.de> (raw)
Should still apply on latest Linux tree, I can resubmit if not.
Would be great if hpa can push this into a x86 branch to get
this into linux-next and into Linus' tree with the next merge
window.
Thanks,
Thomas
