From 9d291e787b2b71d1b57e5fbb24ba9c70e748ed84 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Wed, 2 May 2007 19:27:06 +0200 Subject: [PATCH] x86-64: Assembly safe page.h and pgtable.h This patch makes pgtable.h and page.h safe to include in assembly files like head.S. Allowing us to use symbolic constants instead of hard coded numbers when refering to the page tables. This patch copies asm-sparc64/const.h to asm-x86_64 to get a definition of _AC() a very convinient macro that allows us to force the type when we are compiling the code in C and to drop all of the type information when we are using the constant in assembly. Previously this was done with multiple definition of the same constant. const.h was modified slightly so that it works when given CONFIG options as arguments. This patch adds #ifndef __ASSEMBLY__ ... #endif and _AC(1,UL) where appropriate so the assembler won't choke on the header files. Otherwise nothing should have changed. AK: added const.h to exported headers to fix headers_check Signed-off-by: Eric W.

Peter Anvin" Date: Wed, 2 May 2007 19:27:12 +0200 Subject: [PATCH] x86: Clean up x86 control register and MSR macros (corrected) This patch is based on Rusty's recent cleanup of the EFLAGS-related macros; it extends the same kind of cleanup to control registers and MSRs. It also unifies these between i386 and x86-64; at least with regards to MSRs, the two had definitely gotten out of sync. Signed-off-by: H.
