(That tree has some shellcheck patches at the end, not in this series)

Since v7, fixed a couple of Thomas' review comments. Also added
a test for PMC5 counting vs interrupts which is broken on upstream
TCG. And a small fix for SMP+MMU (secondary stack was being allocated
in discontiguous virtual memory if they were started when MMU is
enabled on the primary) discovered while I was making a test case
for TCG TLB races (not yet included in the series).

Thanks,
