- Document this in kbuild.txt
Without this change you have to type each arch separately.

Currently looking up a structure definition in TAGS / tags takes one to
one of multiple "static struct X" definitions in arch sources, which makes
it for many structs practically impossible to get to the required header.
This patch changes the order of sources being tagged to first scan
architecture includes, then the top-level include/ directory, and only
then the rest. It also takes into account, that many architectures have
more than one include directory, i.e., not only arch/$ARCH/include, but
also arch/$ARCH/mach-X/include etc.

Better dwarf2 unwind information is a good thing, it allows better
debugging with kgdb and crash and helps systemtap.
Commit 003086497f ("Build with
-fno-dwarf2-cfi-asm") disabled some CFI information globally to work
around a module loader bug on powerpc.
But this disables the better unwind tables for all architectures, not just
powerpc. Move the workaround to powerpc and also add a suitable comment
that's it really a workaround.
This improves dwarf2 unwind tables on x86 at least.

1. Fix a little format issue.
2. Check the return of "Getopt::Long::GetOptions". Output usage and
exit if it get error.
3. Change $ARGV[$#ARGV] to $ARGV[0].
4. Change the code which get $modulefile from modinfo. Replace the
pipeline with `modinfo -F filename $module`.
4. Change usage from "Specify the module directory name" to "Specify the
module filename".

The markup_oops.pl have 3 troubles to support cross-compiler environment:
1. It use objdump directly.
2. It use modinfo to get the message of module.
3. It use hex function that cannot support 64-bit number in 32-bit arch.
This patch add 3 options to markup_oops.pl:
1. -c CROSS_COMPILE Specify the prefix used for toolchain.
2. -m MODULE_DIRNAME Specify the module directory name.
3. Change hex function to Math::BigInt->from_hex.
After this patch, parse the x8664 oops in x86, we can:
cat amd64m | perl ~/kernel/tmp/m.pl -c /home/teawater/kernel/bin/x8664- -m ./e.ko vmlinux
Thanks,

Also, add a note that "unmaintained" files below scripts/ should go via
the kbuild tree (best current practice).

The mkspec script hardcodes "/var/tmp" into the generated rpm spec file's
BuildRoot. The user, however, may have a custom setting for %_tmppath,
which should be used in BuildRoot. This patch changes mkspec's
BuildRoot output to appropriately use %_tmppath.
