[GIT PULL] rcu: infrastructure for debugobjects checking

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello, Ingo,

Here are the first three commits from Mathieu's debugobjects series
(http://lwn.net/Articles/387344/).  The first two provide the debugobjects
infrastructure and the RCU APIs, and the third applies these APIs to
the RCU implementation itself.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next

Once these three reach mainline, I will submit the next six commits
to their respective trees (powerpc, block, staging, fs, mm, and selinux).
The maintainers have been CCed on the the earlier LKML patchsets.
Once these six commits reach mainline, I will send you a pull request
for the remaining two commits.

Then on to Arnd's "sparse" checks, which are still being refined.

							Thanx, Paul
