We need a location for generated files.
Today they are spread over several places and bringing them
together to a common place makes it obvious hat is generated
and what isreal files.Al Viro originally suggested: include/gen
Linus suggested to spell it out.This patch implement support for
include/generated
All files in include/generated are ignored by git.
include/generated is removed during "make mrproper".With this we are ready to implement support for include/generated
in the various architctures and in the base kernel.Signed-off-by: Sam Ravnborg

Make it possible for the linker to discard local symbols from vmlinux as
they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause
dump_stack() and get_wchan() to produce useless information under some
circumstances.With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause
the build to supply -X to the linker to tell it to strip temporary local
symbols.This doesn't seem to cause gdb any problems.

This adds in support for building with ARCH=sh64 using the sh SRCARCH.
This tidies up the randconfig generation somewhat to make sure that we
don't end up with impossible configurations, and without having to rely
on things like KCONFIG_ALLCONFIG to detect the proper CPU support subset.Signed-off-by: Paul Mundt

With a sufficiently new compiler and binutils, code which wasn't
previously generating .eh_frame sections has begun to. Certain
architectures (powerpc, in this case) may generate unexpected relocation
formats in response to this, preventing modules from loading.While the new relocation types should probably be handled, revert to the
previous behaviour with regards to generation of .eh_frame sections.(This was reported against Fedora, which appears to be the only distro
doing any building against gcc-4.4 at present: RH bz#486545.)Signed-off-by: Kyle McMartin

"We have several architectures that plays strange games with $(CC) and

This makes sure that gcc doesn't try to optimize away wrapping
arithmetic, which the kernel occasionally uses for overflow testing, ie
things likeif (ptr + offset < ptr)
which technically is undefined for non-unsigned types. See
http://bugzilla.kernel.org/show_bug.cgi?id=12597
for details.
Not all versions of gcc support it, so we need to make it conditional
(it looks like it was introduced in gcc-3.4).Reminded-by: Alan Cox

Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
tree under SCM. This is due to KERNELRELEASE being different when the initial make
is run and when make is run from rpmbuild.mkspec creates kernel.spec using KERNELRELEASE:
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
additional version info from SCM. Next, the srctree is tarred up and SCM
information is excluded.rpmbuild reruns make and in the process generates a new include/config/kernel.release
and thus a new KERNELRELEASE. However this time the SCM information is gone so
KERNELRELEASE no longer has the additional version information. When "make modules_install"
runs, it uses the new KERNELRELEASE value to determine where to install the modules.
This conflicts with where the spec file assumes they are going because of the
mis-matching KERNELRELEASE versions.+ INSTALL_MOD_PATH=/var/tmp/kernel-2.6.29rc4tip01479g5d85422-root

It's useful to already have the source symlink in a
objdir when one just runs make *config. Then one
can domkdir obj-allyes

Impact: no default -fno-stack-protector if stackp is enabled, cleanup
Stackprotector make rules had the following problems.
* cc support test and warning are scattered across makefile and
kernel/panic.c.* -fno-stack-protector was always added regardless of configuration.
Update such that cc support test and warning are contained in makefile
and -fno-stack-protector is added iff stackp is turned off. While at
it, prepare for 32bit support.Signed-off-by: Tejun Heo

Merge header files for m68k and m68knommu to the single location:
arch/m68k/include/asm
The majority of this patch was the result of the
script that is included in the changelog below.The script was originally written by Arnd Bergman and
exten by me to cover a few more files.When the header files differed the script uses the following:
The original m68k file is named _mm.h [mm for memory manager]
The m68knommu file is named _no.h [no for no memory manager]The files uses the following include guard:
This include gaurd works as the m68knommu toolchain set
the __uClinux__ symbol - so this should work in userspace too.Merging the header files for m68k and m68knommu exposes the
(unexpected?) ABI differences thus it is easier to actually
identify these and thus to fix them.The commit has been build tested with both a m68k and
a m68knommu toolchain - with success.The commit has also been tested with "make headers_check"
and this patch fixes make headers_check for m68knommu.The script used:

1) People have reported compatibility issues with binutils due to
lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2
