Linus Torvalds ae3e462828 Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild changes from Michal Marek:
 "The main part of kbuild for v3.7 contains:
   - Fix for scripts/Makefile.modpost to not choke on a '.ko' substring
     in the build directory path
   - Two warning fixes (modpost and main Makefile)
   - __compiletime_error works also with gcc 4.3
   - make tar{gz,bz2,xz}-pkg uses default compression settings instead
     of saving as many bytes as possible (this should actually be in the
     misc branch, I don't know why I applied it here)."

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  compiler-gcc4.h: correct verion check for __compiletime_error
  modpost: Permit .GCC.command.line sections
  Kbuild: use normal compression settings for tar*-pkg
  scripts/Makefile.modpost: error in finding modules from .mod files.
  kbuild: Remove useless warning while appending KCFLAGS

Andi Kleen b589c8ae09 Kbuild: use normal compression settings for tar*-pkg
For large kernel configurations (like a distribution kernel)
targz-pkg takes a quite long time to just do the compression.
I clocked it at 15+mins for a SUSE kernel like config on a fast
system.  And tarxz and bzip2 are even slower.

The main reason is that the script that is doing the taring sets
the highest compression level (-9).  When I change it to just
use the defaults the gzip time for the same kernel goes down
to ~3 mins. I haven't tested xz and bzip, but I expect those
to be much faster too.

I'm not willing to wait that long for a small compression
gain. So just change the script to use the defaults.

Michal Marek fe04ddf7c2 kbuild: Do not package /boot and /lib in make tar-pkg
There were reports of users destroying their Fedora installs by a kernel
tarball that replaces the /lib -> /usr/lib symlink. Let's remove the
toplevel directories from the tarball to prevent this from happening.

Michal Marek 91d161857c scripts/package: tar-pkg: use tar --owner=root
Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root.  Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.

Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.

Jan-Benedict Glaw 6073aa643f kbuild: tar-pkg with out-out-tree building
Fix out-of-tree builds for the tar-pkg targets

When I wrote the buildtar script, I didn't even think about
out-of-tree builds because I didn't use these back then. This patch
throughoutly uses ${objtree} instead of `pwd`.

Also, the kernel version is no longer manually built. Instead, it will
properly use $KERNELRELEASE .  Installing modules is only done if
CONFIG_MODULES is set.

Jan-Benedict Glaw 6d983feab8 [PATCH] kbuild: create tarballs
It adds tarball packaging, which I prefer for distribution.
Also one of the two blanks after @echo is removed. One seems to be enough :)
