"mkdir -p" does not only mean not to complain if the directory already
exists, but also to create the parent directories if needed. This patch
removes "lib" from the list of directories to create as we will also create
"lib/modules".

The following patch extends kbuild/defconfig tags support to exuberant
ctags. The previous support is only for emacs ctags/etags programs.
This patch also corrects the kconfig regex for the emacs invocation.
Previously it would miss some instances because it assumed /^config
instead of /^[ \t]*config

I noticed a few typos while reading makefiles.txt to learn about the
kbuild system. Attached is a patch against 2.6.18 to fix them.
Remove trailing whitespace while we are there..

Based on conversations with greg kh (and noticing a simple typo),
these are the actual minimal versions for 2.6.18.

At stage 2 modpost utility is used to check modules. In case of unresolved
symbols modpost only prints warning.
IMHO it is a good idea to fail compilation process in case of unresolved
symbols (at least in modules coming with kernel), since usually such errors
are left unnoticed, but kernel modules are broken.
- new option '-w' is added to modpost:
if option is specified, modpost only warns about unresolved symbols
- modpost is called with '-w' for external modules in Makefile.modpost

hostprogs-y only supported creating output directory for the final
program. Extend this to also cover the situation where a .o
file (used when host program is made from compositie objects) is
locate in another directory.
First user of this is the built-in lxdialog that.

tell why a a target got build
enabled by make V=2
Output (listed in the order they are checked):
(1) - due to target is PHONY
(2) - due to target missing
(3) - due to: file1.h file2.h
(4) - due to command line change
(5) - due to missing .cmd file
(6) - due to target not in $(targets)
(1) We always build PHONY targets
(2) No target, so we better build it
(3) Prerequisite is newer than target
(4) The command line stored in the file named dir/.target.cmd
differed from actual command line. This happens when compiler
options changes
(5) No dir/.target.cmd file (used to store command line)
(6) No dir/.target.cmd file and target not listed in $(targets)
This is a good hint that there is a bug in the kbuild file

This has the advantage that all section mismatch checks are run regardless
of modules being enabled or not.
When running modpost on vmlinux output:
MODPOST vmlinux
When running modpost on modules output count of modules like this:
MODPOST 5 modules

No file in rpm binary package should have the RPM_BUILD_ROOT string in it.
To simplify building of external modules, our kernel-source package
contains some temp files from the Kbuild system. asm/asm-offsets.h is one
of the files that contains the absolute path if make O=$O is used.
* This file was generated by /var/tmp/kernel-source-2.6.14_rc4-build/usr/src/linux-2.6.14-rc4-2/Kbuild
Remove the $RPM_BUILD_ROOT string in the shipped tempfile.

This patch contains a raw copy of unifdef.c
Next patch will modify it and add infrastructure to use it
Adding unifdef to the kernel is acked by the author.
The reason to add unifdef as part of the kernel source is that it is not
yet a common utility on most distributions.

Consistently decide when to rebuild a target across all of
if_changed, if_changed_dep, if_changed_rule.
PHONY targets are now treated alike (ignored) for all targets
While add it make Kbuild.include almost readable by factoring out a few
bits to some common variables and reuse this in Makefile.build.

Kconfig doesn't currently handle config files with DOS line endings.
While these are, of course, an abomination, etc, etc, it can be handy
to not have to convert them first. It's also a tiny patch and even adds
support for lines ending in just \r or even \n\r.

Have ocfs2_process_blocked_lock() call ocfs2_generic_unblock_lock(), which
gets to be ocfs2_unblock_lock() now that it's the only possible unblock
function.

specific unblock functions.

Allow a lock type to specifiy whether it makes use of the LVB. The only type
which does this right now is the meta data lock. This should save us some
space on network messages since they won't have to needlessly transmit value
blocks.

This was always defined to the same function in all locks, so clean things
