Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.Reported-by: Simon Horman

Apparently not all versions of glibc and utilities treat an empty
LC_ALL as nonexistent, causing error messages to be garbled. Instead,
explicitly unexport it from the environment.Reported-and-tested-by: Masami Hiramatsu

There are a number of common Unix constructs like character ranges in
grep/sed/awk which don't work as expected with LC_COLLATE set to other
than C. Similarly, set LC_CTYPE and LC_NUMERIC to C to avoid other
nasty surprises.In order to make sure these actually take effect we also have to
clear LC_ALL.Signed-off-by: H. Peter Anvin

To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.Signed-off-by: Michal Marek

We no longer use this directory for generated files and
all architectures has moved their header files so no
symlink tricks are needed either.Drop the symlink and drop the ARCH check.
If we really need to check that the SRCARCH has not changed
when we build a kernel we can add this check back - but then we will
find a more convenient way to store the info.Signed-off-by: Sam Ravnborg

The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.Signed-off-by: Sam Ravnborg

The namespace used in arch/$ARCH/include is different from
what is used in include/ except for the include/asm directory.This patch gives the arch/$ARCH/include/asm directory priority
over include/asm.When we add asm-offsets.h to arch/$ARCH/include/asm/ this
patch makes sure we pick up the arch specific version
and not the one we have in include/asm.The situation with an asm-offsets.h file located in
both include/asm _and_ arch/$ARCH/include/asm will happen
when we move more files over to include/generated.This happens because in some cases it is not practical
to rename all users so we simply add a file
in arch/$ARCH/include/asm that includes the generated version.This is the solution we use for asm-offsets.h as an example.

If the user has an older version of objcopy, that can not handle
converting local symbols to global and vice versa, then some
functions will not be part of the dynamic function tracer. The current
code in recordmcount.pl will print a warning in this case. Unfortunately,
there exists lots of files that may have this issue with older objcopys
and this will cause a warning for every file compiled with this
issue.This patch solves this overwhelming output by creating a
.tmp_quiet_recordmcount file on the first instance the warning is
encountered. The warning will not print if this file exists.The temp file is deleted at the beginning of the compile to ensure that
the warning will happen once again on new compiles (because the issue
is still present).Reported-by: Andrew Morton

Revert commit 575543347b5baed0ca927cb90ba8807396fe9cc9
It caused following issues:
- On architectures where ARCH= setting is used to select between
32 and 64 bit this was no longer possible without "make mrproper"
- If ARCH was changed then kbuild refused to run "make mrproper"
because ARCH had changed
- When CROSS_COMPILE was changed people were asked to run "make mrproper"
but kbuild refused to run "make mrproper" because CROSS_COMPILE changed.
- Spaces in CROSS_COMPILE was not 'supported'
- If an non-existing ARCH= was used kbuild could get stuckLessons learned:
. Despite being simple and straghtforward people uses very different
approaches when building the kernel.. CROSS_COMPILE is sometimes used for ccache despite cache being
only a CC frontend so one would have expected CC to be
used for this purpose.. And obviously this was not tested widely enough.

I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in
order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when
'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about
whether people perhaps meant -rc1 or -rc2.

Albin Tonnerre reported:
Bash 4 filters out variables which contain a dot in them.
This happends to be the case of CPPFLAGS_vmlinux.lds.
This is rather unfortunate, as it now causes
build failures when using SHELL=/bin/bash to compile,
or when bash happens to be used by make (eg when it's /bin/sh)Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.This is also nice cleanup as we move the information out where
it is used.Notes for the different architectures touched:
arm - we use an already exported symbol
cris - we use a config symbol aleady available
[Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
Added a few variables to CPPFLAGS - they are only used by
the linker script.
[Not build tested]
powerpc - removed assignment that is not needed
[not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation

When building a kernel for a different architecture
kbuild requires the user always to specify ARCH and
CROSS_COMPILE on the command-line.We use the asm symlink to detect if user forgets to
specify the correct ARCH value - but that symlink
is about to die. And we do now want to loose this check.This patch save the settings of ARCH and CROSS_COMPILE
in two files named:include/generated/kernel.arch
include/generated/kernel.crossThe settings are saved during "make *config" time
and always read.If user try to change the settings we error out.
This works both for plain builds and for O=...
builds.So now you can do:
$ mkdir sparc64
$ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig
$ cd sparc64
$ makeNotice that you no longer need to tell kbuild
the settings of ARCH and CROSS_COMPILE when you type make
in the output directory.Likewise for plain builds where you do not use O=...

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:make INSTALLKERNEL=arm-installkernel install
With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]This patch undos what Ian did in commit:
