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 variable2a113281f5cd2febbab21a93c8943f8d3eece4d3
-> kconfig: use $K64BIT to set 64BIT with all*config targetsRoman 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 | 64bitThe 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.Signed-off-by: Sam Ravnborg

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-bitLikewise for i386 with the addition that
i386 is default is you say ARCH=x86.Signed-off-by: Sam Ravnborg

For x86 ARCH may say i386 or x86_64 and soon x86.

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:

The patch is big. Really big. You just won't believe how vastly hugely
mindbogglingly big it is. I mean you may think it's a long way down the
road to the chemist, but that's just peanuts to how big the patch from
2.6.23 is.But it's all good.

make vmlinux would delete the content of $(MODVERDIR)
equals .tmp_versions. This caused a subsequent
make modules_install to fail.Fix it so we clean the directory only for the
modules build - but we still unconditionally create it so
we can do:
make dir/file.ko
without a preceeding make modules.Reported by David Miller

When building a specific module before doing a total kernel
build it failed because $(MORVERDIR) were missing.
Creating the MODVERDIR explicit (independent of KBUILD_MODULES)
fixed this. As a side-effect the MODVERDIR will be created
also for a non-module build - but no harm done by that.Signed-off-by: Sam Ravnborg

When building embedded systems in a cross-compile environment and
populating a target's file system image, we don't want to run the
depmod on the host as we may be building for a completely different
architecture. Since there's no such thing as a cross-depmod, we
just disable running depmod in the cross-compile case and we just
run depmod on the target at bootup.Inspired by patches from Christian, Armin and Deepak.
This solves: http://bugzilla.kernel.org/show_bug.cgi?id=3881

We often hit the situation where the asm symlink
in include/ points to the wrong architecture.
In 9 out of 10 cases thats because we forgot to set
ARCH but sometimes we just reused the same tree
for another ARCH. For the merged x86 tree we need
to create a new symlink but this is not obvious.
So with the following patch we check if the symlink
points to the correct architecture and error
out if this is not the case.Signed-off-by: Sam Ravnborg

Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree). Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.I did not try to address make -j for mixed dot-config and no-dot-config
targets. Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.Signed-off-by: Milton Miller

The assembler for a while now supports -gdwarf to generate source line info
just like the C compiler does. Source-level assembly debugging sounds like an
oxymoron, but it is handy to be able to see the right source file and read its
comments rather than just the disassembly. This patch enables -gdwarf for
assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.Signed-off-by: Roland McGrath
