Don't bother doing `svn st` as it takes a retarded amount of time when

Subject: [PATCH 2/8] kbuild: add vmlinux to kernel rpm
We are building an automated system to test kernels weekly and need to
provide an rpm to our QA dept. We would like to use the ability to create
kernel rpms already in the kernel's Makefile, but need the vmlinux file
included in the rpm for later debugging.
This patch adds a compressed vmlinux to the kernel rpm when doing a
make rpm-pkg or binrpm-pkg and upon install places the vmlinux file in /boot.

<4>[ 0.327595] initcall .migration_init+0x0/0x9c returned 1 after 0 usecs

ALLSOURCE_ARCHS support for tags/cscope" breaks tags generation for
Kconfig symbols.
Steps to reproduce:
make tags
vi -t PROC_FS
It should jump to 'config PROC_FS' line.

Subject: [PATCH 5/8] kbuild: add sys_* entries for syscalls in tags
Currently, it is no longer possible to use the tags file to jump to
system call function definitions with sys_foo, because the definitions
are obscured by use of the SYSCALL_DEFINE* macros.
This patch adds the appropriate option to ctags to make it see through
the macro. Also, it adds the ENTRY() work already done for Exuberant
to Emacs too.

Subject: [PATCH 6/8] scripts: add x86 register parser to markup_oops.pl
An oops dump also contains the register values.
This patch parses these for (32 bit) x86, and then annotates the
disassembly with these values; this helps in analysis of the oops by the
developer, for example, NULL pointer or other pointer bugs show up clearly
this way.

It's useful to already have the source symlink in a
objdir when one just runs make *config. Then one
can do
mkdir obj-allyes
cd obj-allyes
make -C ../sourcedir O=$(pwd) allyesconfig
./source/scripts/config --disable debug_info
make CC=icecc -j18
without having to interrupt the make first just to
get the source symlink.
