[Sam Ravnborg]

kbuild updates for 2.6.19.

Please pull from:

	git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git

All patches except a bunch of documentation fixes has been in -mm at least
a couple of -mm's with no or little feedback.
The headlines:

o Added unifdef to the kernel tree to provide better support for headers_*
o Build fails if there are undefined symbols in a module
o Run modpost on vmlinux also in case of non-module build

Patches will be sent to lkml as follow-up to this mail.

It looks like a few patches were eaten on their way to lkml.
So here you have a direct reference to the git tree where
the patches can be seen.

Btw, this shows an irritating bug in your setup: your computer has its 
clock set wildly incorrectly.

Git doesn't really _care_, but if you look at gitweb at this time, it will 
annotate all the commits I pulled from you as being "right now", because 
your computers clock was set several hours into the future, and thus your 
timestamps are crap.

Please fix. The "author" times are correct (they get taken from the emails 
or from the original commit that got cherry-picked, depending on how you 
did things), but look for example at commit 5026b38c:

	author	Randy Dunlap <rdunlap@xenotime.net>
		Fri, 22 Sep 2006 19:37:56 +0000 (12:37 -0700)
	committer	Sam Ravnborg <sam@neptun.ravnborg.org>
		Mon, 25 Sep 2006 11:33:04 +0000 (13:33 +0200)

and I can tell you that you sure as hell didn't commit that on Monday, 
September 25, at 11:33 UTC (or 13:33 in +0200), because right now it's 
2:13 AM in UTC, and the date your commit got marked for is still more than 
nine hours in the future (and was further off when you did it).

I'd suggest running NTP, or at least checking that your date is even 
_remotely_ correctly set on your computer ;)
