From: Keith Owens <kaos@ocs.com.au>
Make it easier to generate maps for debugging kallsyms problems.
debug_kallsyms is only a debugging target so no help or silent mode.

I have a single source tree which I cross compile for a couple of
different architectures using ARHC=foo O=blah etc.
The existing cscope target is very handy but only indexes the current
$(ARCH), which is a pain since inevitably I'm interested in the other
one at any given time ;-). This patch allows me to pass a list of
architectures for cscope to index. e.g.
make ALLSOURCE_ARCHS="i386 arm" cscope
This change also works for etags etc, and I presume it is just as useful
there.

I tried the Linux Makefile 'make cscope' target, and found that the
generated database is not compatible with 'cscope.el' under XEmacs.
The thing is that 'cscope.el' does not allow setting the command line
options to the 'cscope' commands it runs, and it errors with a message
about the options not matching the ones used to generate the index.
It turns out the cscope designers already thought of this. The
options can be written into the "cscope.files". The included patch
moves the "-q" and "-k" options from the 'cmd_cscope' to the
'cmd_cscope-file', echoing them into the top of the files listing.
Now the index is generated with the "-q" option, and when 'cscope.el'
performs it's search, it uses that argument as well. Lookups are fast
and everyone is happy.

Using the syntax:
make dir/module.ko
kbuild now allows one to build a module including the final link stage.
This is usefull when one only wants to compile a single module and thus do
not have to wait until a full kernel has finished compiling. Tested by:

make O=/dir TAGS
fails with:
MAKE TAGS
find: security/selinux/include: No such file or directory
find: include: No such file or directory
find: include/asm-i386: No such file or directory
find: include/asm-generic: No such file or directory
The problem is in this line:
ifeq ($(KBUILD_OUTPUT),)
KBUILD_OUTPUT is not defined (ever) after make reruns itself. This line is
used in the TAGS, tags, and cscope makes.

Ok, a lot of things were pending after the 2.6.12 release, let's try to
start calming things down again.

Frame pointers are supposed to enable debuggers to reliably tell where a
call comes from. That is defeated by GCC's sibling call optimization (aka
tail recursion elimination).
This patch turns this optimization off when compiling with frame pointers.

Getting ready for the real release..

The arch Makefile may override the include path order, which is used by Xen
(and UML?) to make sure include/asm-xen is searched before
include/asm-i386.
The Makefile change to 2.6.12-rc4 made the top Makefile always override the
value specified by the arch Makefile. This trivial patch makes the Xen
kernel compile again.

I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the
"cmd_tags" variable has been changed in a way incompatible with *emacs
ctags. Since the "--extra" option exists only in "exuberant ctags", it
should be included in the CTAGSF shell variable.

Move definition of NOSTDINC_FLAGS below inclusion of arch Makefile, so
any arch specific settings to $(CC) takes effect before looking up the
compiler include directory.
The previous solution that replaced ':=' with '=' caused gcc to be
invoked one additional time for each directory visited.
This decreases kernel compile time with 0.1 second (3.6 -> 3.5 seconds) when
running make on a fully built kernel

Releasing this will also make "git" the official source control
thing. Here's to hoping for the best.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
