2009-03-14x86-32: use brk segment for allocating initial kernel pagetableJeremy Fitzhardinge1-3/+0
Impact: use new interface instead of previous ad hoc implementation Rather than having special purpose init_pg_table_start/end variables to delimit the kernel pagetable built by head_32.S, just use the brk mechanism to extend the bss for the new pagetable. This patch removes init_pg_table_start/end and pg0, defines __brk_base (which is page-aligned and immediately follows _end), initializes the brk region to start there, and uses it for the 32-bit pagetable.

2009-02-11x86: rename *-defs.h to *-_types.h for consistencyJeremy Fitzhardinge1-2/+2
The kernel tends to call definition-only headers *_types.h, so rename the x86 page/pgtable headers accordingly. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2008-12-18x86: PAT: change pgprot_noncached to uc_minus instead of strong uc - v3venkatesh.pallipadi@intel.com1-9/+0
Impact: mm behavior change. Make pgprot_noncached uc_minus instead of strong UC. This will make pgprot_noncached to be in line with ioremap_nocache() and all the other APIs that map page uc_minus on uc request.

2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin1-3/+3
