Now done. C/s 13648. I ripped out a few more bits of the Linux RCU
implementation and moved the hooks in schedule.c to a single hook in
do_softirq(). I suspect there is a tradeoff between timeliness of checking
for pending work and building up nice batches of RCU work but checking in
do_softirq() shouldn't mean we're hitting the RCU variables too often.

Also done, by sed. C/s 13649.
