x86: structure declaration renaming
Renamed common structures to vendor specific naming scheme so other vendors will be able to use the same naming convention. Signed-off-by: Peter Oruba <peter.oruba@amd.com> Cc: Tigran Aivazian <tigran@aivazian.fsnet.co.uk> Signed-off-by: Ingo Molnar <mingo@elte.hu>
