thanks Gautham, the patchset from you and Paul looks good to me and i've
applied it to sched-devel.git to get it tested and reviewed some more.

from the Nitpicking Police, there are a couple of minor style
problems/warnings with the code, you can see it via:

scripts/checkpatch.pl --file kernel/rcu*.c

nothing serious - RCU is still one of the cleanest subsystems in the
kernel:

errors lines of code errors/KLOC
kernel/rcuclassic.c 0 575 0
kernel/rcupdate.c 1 138 7.2
kernel/rcupreempt.c 0 953 0
kernel/rcupreempt_trace.c 0 330 0
kernel/rcutorture.c 8 995 8.0

the eventual goal would be to match:

scripts/checkpatch.pl --file kernel/sched*.[ch]

output ;-)

Ingo
