Peter Anvin <hpa@xxxxxxxxx> CommitDate: Fri, 18 Sep 2009 10:21:49 -0700 x86: convert compressed loader to use __HEAD and HEAD_TEXT macros. This has the consequence of changing the section name use for head code from ".text.head" to ".head.text". Linus suggested that we merge the ".text.head" section with ".text" (presumably while preserving the fact that the head code starts at 0). When I tried this it caused the kernel to not boot.
