x86: simplify "make ARCH=x86" and fix kconfig all.config

2007-11-17T16:21:54Z

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: 0f855aa64b3f63d35a891510cf7db932a435c116 -> kconfig: add helper to set config symbol from environment variable 2a113281f5cd2febbab21a93c8943f8d3eece4d3 -> kconfig: use $K64BIT to set 64BIT with all*config targets Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.

Remove x86 merge artifact from top Makefile

2007-11-17T15:27:01Z

The x86 merge modified the tags target to handle the two separate source directories. Remove it now that i386/x86_64 are gone completely. Signed-off-by: Thomas Gleixner

x86: enable "make ARCH=x86"

2007-11-12T20:02:20Z

After unification of the Kconfig files and introducing K64BIT support in kconfig it required only trivial changes to enable "make ARCH=x86". With this patch you can build for x86_64 in several ways: 1) make ARCH=x86_64 2) make ARCH=x86 K64BIT=y 3) make ARCH=x86 menuconfig => select 64-bit Likewise for i386 with the addition that i386 is default is you say ARCH=x86.

x86: do not use $(ARCH) when not needed

2007-11-12T20:02:20Z

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. Signed-off-by: Sam Ravnborg Cc: Thomas Gleixner Cc: Ingo Molnar Cc: "H. Peter Anvin"

kbuild: do not pick up CFLAGS from the environment

2007-11-04T18:00:46Z

Too many people have CFLAGS set to support building userspace. And now Kbuild picks up CFLAGS this caused troubles. Although people should realise that setting CFLAGS has a 'global' effect the impact on the kernel build is a suprise. So change kbuild to pick up value from KCFLAGS that is much less used. When kbuild pick up a value it will warn like this: Makefile:544: "WARNING: Appending $KCFLAGS (-O3) from environment to kernel $CFLAGS" Signed-off-by: Sam Ravnborg Cc: Thomas Bächler Cc: David Miller Cc: Ingo Molnar

sh: Correct SUBARCH matching.

2007-11-02T03:22:47Z

When configuring the kernel natively the uname matching is off, so fix up the uname mangling to get the proper SUBARCH. Needs an explicit range so that SH-5 doesn't break. Signed-off-by: Mike Frysinger Signed-off-by: Paul Mundt

x86: move i386 and x86_64 Makefiles to arch/x86

2007-10-25T20:27:34Z

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
