	Move the headers to include/asm-x86 and fixup the header install make rules Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2007-05-02	[PATCH] i386: Enable support for fixed-range IORRs to keep RdMem & WrMem in sync	Bernhard Kaindl	1	-0/+5
	If our copy of the MTRRs of the BSP has RdMem or WrMem set, and we are running on an AMD64/K8 system, the boot CPU must have had MtrrFixDramEn and MtrrFixDramModEn set (otherwise our RDMSR would have copied these bits cleared), so we set them on this CPU as well. This allows us to keep the AMD64/K8 RdMem and WrMem bits in sync across the CPUs of SMP systems in order to fullfill the duty of system software to "initialize and maintain MTRR consistency across all processors." as written in the AMD and Intel manuals. If an WRMSR instruction fails because MtrrFixDramModEn is not set, I expect that also the Intel-style MTRR bits are not updated.

2007-05-02	[PATCH] x86: Clean up x86 control register and MSR macros (corrected)	H. Peter Anvin	1	-0/+273
	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.
