x86: convert trivial headers to asm-generic version
For these nine header files, the asm-generic version should be semantically identical to what is in x86. Change the contents to be binary identical, for better review. Signed-off-by: Arnd Bergmann <arnd@arndb.de> LKML-Reference: <cover.1245354003.git.arnd@arndb.de> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
