Peter Anvin Date: Mon Jul 23 18:23:47 2007 -0700 lguest: remove use of boot_params macros Remove old-style boot_params macros in lguest. Signed-off-by: H. Peter Anvin commit c85f64831afc1bed5a453e5e815291a80463c9a4 Author: H. Peter Anvin Date: Wed Jul 18 21:22:10 2007 -0700 [x86] Stop using macros for struct boot_params members Now when struct boot_params is a proper structure, there is no need to use hacky macros to refer to them. Additionally, unify under for both x86 architectures (x86-64 had which was unique to that architecture.) Signed-off-by: H.
