Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6:
get rid of nameidata_dentry_drop_rcu() calling nameidata_drop_rcu()
drop out of RCU in return_reval
split do_revalidate() into RCU and non-RCU cases
in do_lookup() split RCU and non-RCU cases of need_revalidate
nothing in do_follow_link() is going to see RCU
task_show_regs used to be a debugging aid in the early bringup days
of Linux on s390. /proc/<pid>/status is a world readable file, it
is not a good idea to show the registers of a process. The only
correct fix is to remove task_show_regs.
