Sam Ravnborg df9df036d3 kbuild: fix 'make all install_modules install'
The command 'make all modules_install install' would fail
in a virgin tree - pointing at a non-existing directory under
/lib/modules/xxx

KERNELRELEASE is part of MODLIB and we need to create .kernelrelease
before we can properly evaluate KERNELRELEASE,
Changing MODLIB to the recursively expanded flavor let it pick up
the correct KERNELRELEASE value.

Sam Ravnborg 2244cbd8a9 kbuild: create .kernelrelease at *config step
To enable 'make kernelrelease' earlier now create .kernelrelease when
one of the *config targets are used.
Also introduce KERNELVERSION - only user is kconfig.
KERNELVERSION was needed to display kernel version in menuconfig -
KERNELRELEASE is not valid until configuration has completed.
kconfig files modified to use KERNELVERSION.

Paul Mackerras 820a8ce793 powerpc: Make ARCH=powerpc the default for 32-bit ppc
This makes ARCH=powerpc the default on 32-bit powerpc machines,
where uname -m returns ppc, as well as on 64-bit powerpc machines.
Most people who would be likely to build their own kernels on
32-bit powerpc machines would be using powermacs or CHRP machines,
both of which are supported with ARCH=powerpc now.  Embedded ppc
developers whose ports haven't been moved over to arch/powerpc
yet will have to explicitly set ARCH=ppc now.

Sam Ravnborg cb58455c48 kbuild: KERNELRELEASE is only re-defined when buiding the kernel
To avoid running setlocalversion as root no longer (re-)define
KERNELRELEASE for each run. With this patch KERNELRELEASE is
only re-read when we do an actual kernel build.
Rationale behind this is "do as little as possible" when executing
make install - as root!

A new file named .kernelrelease is strored in the root of the kernel
tree containing the actual version string.
So when we use do a kernel build the .kernelrelease file will be updated.
But in all other situations it is left as-is.

To make it more visible the kernel now prints out the version being build.
Sample:
Building kernel 2.6.15-g63b794bf-dirty
...
...

The patch also un-exports VERSION PATCHLEVEL SUBLEVEL EXTRAVERSION LOCALVERSION
since all users of these are anyway broken - and none is left in the
tree.

If the file .kconfig.d is missing then make sure to run

-kconfig.d is created by kconfig and is removed as part

This is wrong.  KERNELRELEASE depends on CONFIG_LOCALVERSION, thus you

Paolo 'Blaisorblade' Giarrusso 2ab23c95a0 [PATCH] Kbuild: index asm-$(SUBARCH) headers for UML
In Uml, many definitions are borrowed from underlying subarch headers (with
#include <asm/arch/stuff.h>).  And it has become annoying to keep switching
tag files all time, so by default index the underlying subarch headers too.
Btw, it adds negligible space to the tags file (less than 1M surely, IIRC it
was around 500k over 40M).

Finally, preserve the ALLSOURCE_ARCHS command line option (I hope) - if it is
set, it is used for headers too as before.  But check my construct please, I
didn't test this.

Linus Torvalds 39990b5eb9 ppc64: default build as the merged 'powerpc' architecture
After the last merge of the new unified 'powerpc' architecture, ppc64 no
longer compiles cleanly as a standalone architecture.  Some bits and
pieces still exist as files under the old ppc64 hierarchy, but the old
"ARCH=ppc64" is dead.

So if "uname" says ppc64, that now implies that the default architecture
should be "powerpc".

Zachary Amsden e623a3b808 [PATCH] kbuild: build breaks after -imacros was introduced
I have to revert the recent addition of -imacros to the Makefile to get my
tool chain to build.  Without the change, below, I get:

Note that this looks entirely like a toolchain bug.  Here is the offending command:

[pid 12163] execve("/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", ["/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", "-lang-asm", "-nostdinc", "-Iinclude", "-Iinclude/asm-i386/mach-default", "-D__GNUC__=3", "-D__GNUC_MINOR__=2", "-D__GNUC_PATCHLEVEL__=2", "-D__GXX_ABI_VERSION=102", "-D__ELF__", "-Dunix", "-D__gnu_linux__", "-Dlinux", "-D__ELF__", "-D__unix__", "-D__gnu_linux__", "-D__linux__", "-D__unix", "-D__linux", "-Asystem=posix", "-D__NO_INLINE__", "-D__STDC_HOSTED__=1", "-Acpu=i386", "-Amachine=i386", "-Di386", "-D__i386", "-D__i386__", "-D__tune_i386__", "-D__KERNEL__", "-D__ASSEMBLY__", "-isystem", "/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include", "-imacros", "include/linux/autoconf.h", "-MD", "arch/i386/kernel/.entry.o.d", "arch/i386/kernel/entry.S", "-o", "/tmp/ccOlsFJR.s"]

Which should execute properly, I think.  But it does not:

zach-dev:linux-2.6.14-zach-work $ make
  CHK     include/linux/version.h
  CHK     include/linux/compile.h
  CHK     usr/initramfs_list

make: *** [arch/i386/kernel] Error 2

gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

Deprecating the -imacros fixes the build for me.  It does not appear to be a
simple argument overflow problem in trapcpp0, since deprecating all the defines
reproduces the problem as well.  Also, switching -imacros to -include fixes the
problem.

Russell King 2dd34b488a [PATCH] kbuild: permanently fix kernel configuration include mess
Include autoconf.h into every kernel compilation via the gcc command line
using -imacros.  This ensures that we have the kernel configuration
included from the start, rather than relying on each file having #include
<linux/config.h> as appropriate.  History has shown that this is something
which is difficult to get right.

Since we now include the kernel configuration automatically, make
configcheck becomes meaningless, so remove it.

Sam Ravnborg 5bb7826900 kbuild: rename prepare to archprepare to fix dependency chain
When introducing the generic asm-offsets.h support the dependency
chain for the prepare targets was changed. All build scripts expecting
include/asm/asm-offsets.h to be made when using the prepare target would broke.
With the limited number of prepare targets left in arch Makefiles
the trivial solution was to introduce a new arch specific target: archprepare

The dependency chain looks like this now:

prepare
  |
  +--> prepare0
         |
         +--> archprepare
                |
		+--> scripts_basic
                +--> prepare1
                       |
                       +---> prepare2
                               |
                               +--> prepare3

So prepare 3 is processed before prepare2 etc.
This guaantees that the asm symlink, version.h, scripts_basic
are all updated before archprepare is processed.

prepare0 which build the asm-offsets.h file will need the
actions performed by archprepare.

The head target is now named prepare, because users scripts will most
likely use that target, but prepare-all has been kept for compatibility.
