David Howells 5d7d18f5bc kbuild: make it possible for the linker to discard local symbols from vmlinux
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.

Paul Mundt 3cc000b583 sh: Plug in support for ARCH=sh64 using sh SRCARCH.
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.

Kyle McMartin 003086497f Build with -fno-dwarf2-cfi-asm
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.)

Linus Torvalds d0115552cd Move cc-option to below arch-specific setup
Sam Ravnborg says:
 "We have several architectures that plays strange games with $(CC) and
  $(CROSS_COMPILE).

  So we need to postpone any use of $(call cc-option..) until we have
  included the arch specific Makefile so we try with the correct $(CC)
  version."

Linus Torvalds 68df3755e3 Add '-fwrapv' to gcc CFLAGS
This makes sure that gcc doesn't try to optimize away wrapping
arithmetic, which the kernel occasionally uses for overflow testing, ie
things like

	if (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).

Josh Hunt b925dbfe3c kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree
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:

<mkspec>
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""
</mkspec>

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.

Sam Ravnborg 49148020bc m68k,m68knommu: merge header files
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 <file>_mm.h  [mm for memory manager]
The m68knommu file is named <file>_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.

Jan Beulich 9bb482476c allow stripping of generated symbols under CONFIG_KALLSYMS_ALL
Building upon parts of the module stripping patch, this patch
introduces similar stripping for vmlinux when CONFIG_KALLSYMS_ALL=y.
Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of
CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64)
kernels I tested with.

The patch also does away with the need to special case the kallsyms-
internal symbols by making them available even in the first linking
stage.

While it is a generated file, the patch includes the changes to
scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure
here is.

Jan Beulich ad7a953c52 kbuild: strip generated symbols from *.ko
This patch changes the way __crc_ symbols are being resolved from
using ld to do so to using the assembler, thus allowing these symbols
to be marked local (the linker creates then as global ones) and hence
allow stripping (for modules) or ignoring (for vmlinux) them. While at
this, also strip other generated symbols during module installation.

One potentially debatable point is the handling of the flags passeed
to gcc when translating the intermediate assembly file into an object:
passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to
gas whenever is sees any -g* option, even for -g0, and despite the
fact that the compiler would have already produced all necessary debug
info in the C->assembly translation phase. I took the approach of just
filtering out all -g* options, but an alternative to such negative
filtering might be to have a positive filter which might, in the ideal
case allow just all the -Wa,* options to pass through.

Sam Ravnborg 31110ebbec kbuild: fix make incompatibility
"Paul Smith" <psmith@gnu.org> reported that we would fail
to build with a new check that may be enabled in an
upcoming version of make.

The error was:

      Makefile:442: *** mixed implicit and normal rules.  Stop.

The problem is that we did stuff like this:

config %config: ...

The solution was simple - the above was split into two with identical
prerequisites and commands.
With only three lines it was not worth to try to avoid the duplication.

Sam Ravnborg 5e53879008 sparc,sparc64: unify Makefile
To unify Makefile for sparc and sparc64 a few other steps was needed:
1) separate defconfig files for sparc and sparc64 is required,
   so locate these in arch/sparc/configs
2) removoval of hack in toplevel Makefile to deal with that
   headers was in a separate directory compared to the rest

The unification of the Makefile required usage of several

    foo-$(CONFIG_SPARCnn) +=

due to a few directories pending unification.
This will be cleaned up when we unify the remaining directories.

Included in this patch are the deletion of a few files in
sparc64 as they are no longer needed: Makefile + Kconfig.
arch/sparc64/ will after this patch is applied only
have four directories (prom, lib, kernel, boot)

Sam Ravnborg a680eedc6c tags and cscope support really belongs in a shell script
as they do not benefit from the make functionality.

Moving the support to a shell script has several benefits:
- The readability of the code has increased a lot
- More people is able to extend the tags support
- We see less changes to the top-level Makefile

The shell script version includes improvements from:
Alexey Dobriyan <adobriyan@gmail.com> (jump to kconfig symbols)
Alexey Dobriyan <adobriyan@gmail.com> (drop ./ in paths)
Ian Campbell <ijc@hellion.org.uk> (simplified find algorithms)

This version has a few caveats:
=> It does not support ALLSOURCE_ARCHS
   - it is easy to add if it is really used
=> It assumes all archs have moved to arch/$ARCH/include
   - until that happens we have a few additional hits in the archs

Sam Ravnborg d8672b40d3 kbuild: expand -I in KBUILD_CPPFLAGS
kbuild failed to expand include flags in KBUILD_CPPFLAGS
resulting in code like this in arch Makefiles:

ifeq ($(KBUILD_SRC),)
KBUILD_CPPFLAGS += -Iinclude/foo
else
KBUILD_CPPFLAGS += -I$(srctree)/include/foo
endif

Move use of LINUXINCLUDE into Makefile.lib to allow
us to expand -I directives of KBUILD_CPPFLAGS so
we can avoid the above code.
