2008-07-08x86: remove acpi_srat config v2Yinghai Lu
use ACPI_NUMA directly and move srat_32.c to mm/ Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: PAT infrastructure patchvenkatesh.pallipadi@intel.com
Sets up pat_init() infrastructure. PAT MSR has following setting. PAT |PCD ||PWT ||| 000 WB _PAGE_CACHE_WB 001 WC _PAGE_CACHE_WC 010 UC- _PAGE_CACHE_UC_MINUS 011 UC _PAGE_CACHE_UC We are effectively changing WT from boot time setting to WC. UC_MINUS is used to provide backward compatibility to existing /dev/mem users(X). reserve_memtype and free_memtype are new interfaces for maintaining alias-free mapping. It is currently implemented in a simple way with a linked list and not optimized. reserve and free tracks the effective memory type, as a result of PAT and MTRR setting rather than what is actually requested in PAT. pat_init piggy backs on mtrr_init as the rules for setting both pat and mtrr are same.

2008-04-17x86: clean up the page table dumper and add 32-bit supportH. Peter Anvin
Clean up the page table dumper (fix boundary conditions, table driven address ranges, some formatting changes since it is no longer using the kernel log but a separate virtual file), and generalize to 32 bits.

2008-04-17x86: add code to dump the (kernel) page tables for visual inspection by ↵Arjan van de Ven
kernel developers This patch adds code to the kernel to have an (optional) /proc/kernel_page_tables debug file that basically dumps the kernel pagetables; this allows us kernel developers to verify that nothing fishy is going on and that the various mappings are set up correctly. This was quite useful in finding various change_page_attr() bugs, and is very likely to be useful in the future as well.

2008-04-17x86: unify arch/x86/mm/MakefileH. Peter Anvin
Unify arch/x86/mm/Makefile between 32 and 64 bits. All configuration variables that are protected by Kconfig constraints have been put in the common part of the Makefile; however, the NUMA files are totally different between 32 and 64 bits and are handled via an ifdef.
