Default Linux 2.6.32.49+drm33.21

I am announcing the release of the 2.6.32.49+drm33.21 longterm tree.

This tree is based on 2.6.32 and generally has all of the stable updates
applied. Except those to the DRM subsystem, which was based on 2.6.33 and
took updates from that upstream stable as long as that existed. It will
continue to add patches to the DRM subsystem as long as they are valid
according to the stable update rules (Documentation/stable_kernel_rules.txt).
DRM patches for this tree should be sent to kernel-team@lists.ubuntu.com.

This release contains patches from upstream 2.6.32.49, but dropped any patches
to the DRM subsystem.

The updated 2.6.32.y-drm33.z tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git
or
git://kernel.ubuntu.com/smb/linux-2.6.32.y-drm33.z.git

and can be browsed through git web via:
http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=summary
or
http://kernel.ubuntu.com/git?p=smb/linux-2.6.32.y-drm33.z.git;a=summary

gcc >= 3.00. For gcc < 3.00, -malign-functions=4 is used.
Note: cc-option-align uses KBUILD_CFLAGS for $(CC) options

+ cc-disable-warning
+ cc-disable-warning checks if gcc supports a given warning and returns
+ the commandline switch to disable it. This special function is needed,
+ because gcc 4.4 and later accept any unknown -Wno-* option and only
+ warn about it if there is another warning in the source file.
+
+ Example:
+ KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable)
+
+ In the above example, -Wno-unused-but-set-variable will be added to
+ KBUILD_CFLAGS only if gcc really accepts it.
+
cc-version
cc-version returns a numerical version of the $(CC) compiler version.
The format is <major><minor> where both are two digits. So for example
