* x86, VisWS: turn into generic arch, flip over VISWS to generic archIngo Molnar2008-07-10
| | | | | | | | | this is the big move: flip over VISWS to generic arch support. From this commit on CONFIG_X86_VISWS is just another (default-disabled) option that turns on certain quirks - no other complications. Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | ... so it could fall back to normal numa and we'd reduce the impact of the NUMAQ subarch.

* x86: add subarch support (for headers) to x86_64Glauber de Oliveira Costa2008-04-17
| | | | | | | | | | this patch allows x86_64 to use subarch mach_ headers in practice, since x86_64 does not have any subarch, it will use mach_default.

* x86: fix vdso_install breaks user "make install"Sam Ravnborg2008-02-19
| | | | | | | | | | | | I suggest to make the vdso_install step independent as in following patch.

* x86: share more options between 32 and 64 bit buildSam Ravnborg2008-01-30
| | | | | | | | | | | | | | | | | | | | | On recommendation from Andi Kleen share a few more options between 32 and 64 bit builds. A defconfig build for i386 did not show any difference in size of text and data. The additional shared options are: -Wno-sign-compare -fno-asynchronous-unwind-tables -mno-sse -mno-mmx -mno-sse2 -mno-3dnow Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: "H.

* x86: unification of arch/x86/MakefilesSam Ravnborg2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unify the 32 and 64 bit specific Makefiles. The unification was simplest to do in one step although the readability of the patch suffers a bit from this. Noteworthy remarks on the unification: - The 64 bit cpu stuff should be moved to Makefile_32.cpu but I did not feel confident doing it due to subtle differences - The use of cflags-y were abandoned since we have seen one bug where we did wrong due to missing assignment to KBUILD_CFLAGS. The cc-option marcro uses KBUILD_CFLAGS. - The "No need to remake" line are deleted. It caused "make -B" to fail - For 64 bit the sub architecture stuff is not used. - The way head64.o is specified could be nicer - but it awaits the introduction of head32.o (which seems like a win to introduce for readability) - Patch is checkpatch clean Patch is tested by doing a defconfig build for i386 and x86_64 and in both cases monitoring that only relevant files were recompiled when applying the patch.

* x86: correctly set UTS_MACHINE for "make ARCH=x86"Andreas Herrmann2007-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | For a kernel built with "make ARCH=x86" the following system information is displayed when running the new kernel $ uname -m x86 On some i386 systems (e.g. K7) we even have the following information $ uname -m x66 This is weird. The usual information for "uname -m" should be "x86_64" on 64-bit and "i386" or "i686" on 32-bit. This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86" won't be used for UTS_MACHINE anymore.

* x86: do not use $(ARCH) when not neededSam Ravnborg2007-11-12
| | | | | | | | | | | For x86 ARCH may say i386 or x86_64 and soon x86. Rely on CONFIG_X64_32 to select between 32/64 or just hardcode the value as appropriate.

* x86: move defconfig files for i386 and x86_64 to x86Sam Ravnborg2007-10-25
| | | | | | | | | | | | With some small changes to kconfig makefile we can now locate the defconfig files for i386 and x86_64 in the configs/ subdirectory under x86. make ARCH=i386 defconfig and make defconfig works as expected also after this change. But arch maintainers shall now update a defconfig file in the configs/ directory. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* x86: move i386 and x86_64 Makefiles to arch/x86Sam Ravnborg2007-10-25
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>
