2009-08-23x86: add specific support for Intel Atom architectureTobias Doerffel
Add another option when selecting CPU family so the kernel can be optimized for Intel Atom CPUs. If GCC supports tuning options for Intel Atom they will be used.

2009-06-18x86: remove all now-duplicate header filesArnd Bergmann
All files that have been made identical to the asm-generic version in the previous patches can now be removed, guaranteeing that this does not introduce semantic changes.

2009-06-18x86: convert almost generic headers to asm-generic versionArnd Bergmann
In x86, mman.h, module.h, scatterlist.h, types.h and ucontext.h can use the asm-generic version by just defining the x86 specific parts locally and falling back on the generic code for the common bits. This patch illustrates the differences between the x86 and asm-generic versions by changing a file that is initially identical to the x86 version to one that is identical to the asm-generic version.

2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
