Tobias Doerffel	366d19e181	x86: add specific support for Intel Atom architecture ... 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. Signed-off-by: Tobias Doerffel <tobias.doerffel@gmail.com> Signed-off-by: H.

Krzysztof Helt	69d45dd1c3	x86: merge winchip-2 and winchip-2a cpu choices ... The Winchip-2 and Winchip-2A cpu choices select the same options for kernel and compiler. Merge them to save few bytes and reduce confusion. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Acked-by: H.

H. Peter Anvin	28f7e66fc1	x86: prevent binutils from being "smart" and generating NOPLs for us ... binutils, contrary to documented behaviour, will generate long NOPs (a P6-or-higher instruction which is broken on at least some VIA chips, Virtual PC/Virtual Server, and some versions of Qemu) depending on the -mtune= option, which is not supposed to change architectural behaviour. Pass an explicit override to the assembler, in case ends up passing the -mtune= parameter to gas (gcc 4.3.0 does not appear to.) Signed-off-by: H.

Sam Ravnborg	74b469f2e6	x86: move i386 and x86_64 Makefiles to arch/x86 ... Moving the ARCH specific Makefiles for i386 and x86_64 required a litle bit tweaking in the top-lvel Makefile. SRCARCH is now set in the top-level Makefile because we need this info to include the correct arch Makefile. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>	2007-10-25 22:27:34 +02:00

Renamed from arch/i386/Makefile.cpu (Browse further)
