Some distributions have enabled the gcc flag -Wformat-security by default.
This results in a number of warnings about format arguments to functions,
sometimes in cases where fixing the warning is not likely to actually fix a
bug. Instead of hand patching a dozens of places (possibly more) that produce
warnings that get ignored anyway we just turn off the flag in the Makefile.Signed-off-by: Floris Kraak

Enable the use of GCC's coverage testing tool gcov [1] with the Linux
kernel. gcov may be useful for:* debugging (has this code been reached at all?)
* test improvement (how do I change my test to cover these lines?)
* minimizing kernel configurations (do I need this option if the
associated code is never run?)The profiling patch incorporates the following changes:
* change kbuild to include profiling flags
* provide functions needed by profiling code
* present profiling data as files in debugfsNote that on some architectures, enabling gcc's profiling option
"-fprofile-arcs" for the entire kernel may trigger compile/link/
run-time problems, some of which are caused by toolchain bugs and
others which require adjustment of architecture code.For this reason profiling the entire kernel is initially restricted
to those architectures for which it is known to work without changes.
This restriction can be lifted once an architecture has been tested
and found compatible with gcc's profiling. Profiling of single files
or directories is still available on all platforms (see config help
text).[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html

The GNU make's origin function know undefined variable well,
so the outer ifdef/endif conditional checking is unneeded.From `info make` documentation, origin will return
`undefined'
if VARIABLE was never defined.
`command line'
if VARIABLE was defined on the command line.
...Therefore, $(origin V) will get a value anyway, killing ifdef/endif is
viable and safe.Furthermore, I've checked the minimal requirements from
Documentation/Changes is GNU make 3.79.1, and that version of GNU make
has support of origin function well already, so now it's safe to kill
the outer conditional checking, without upgrading the minimal
requirements.Signed-off-by: Cheng Renquan

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

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
cd obj-allyes
make -C ../sourcedir O=$(pwd) allyesconfig
./source/scripts/config --disable debug_info
make CC=icecc -j18without having to interrupt the make first just to
get the source symlink.Signed-off-by: Andi Kleen
