all header files. This closes #40, as I think we don't need to invest time to fix this in LinuxBIOSv2, but only in LinuxBIOSv3. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://coreboot.org/repository/LinuxBIOSv3@332 f3766cd6-281f-0410-b1cd-43a5c92072e9
