Revert the part of r239864 (MFC'ed to stable/8 in r241690) which removed
obtaining the SMP mutex around reading registers from other CPUs. As it
turns out, the hardware doesn't really like concurrent IPI'ing causing
adverse effects. Also the thought deadlock when using this spin lock here
and the targeted CPU(s) are also holding or in case of nested locks can't
actually happen. This is due to the fact that on sparc64, spinlock_enter()
only raises the PIL but doesn't disable interrupts completely. Thus direct
cross calls as used for the register reading (and all other MD IPI needs)
still will be executed by the targeted CPU(s) in that case.

- Give PIL_PREEMPT the lowest priority just above low/stray interrupts.
The reason for this is that the SPARC v9 architecture allows nested
interrupts of higher priority/level than that of the current interrupt
to occur (and we can't just entirely bypass this model, also, at least
for tick interrupts, this also wouldn't be wise). However, when a
preemption interrupt interrupts another interrupt of lower priority,
f.e. PIL_ITHREAD, and that one in turn is nested by a third interrupt,
f.e. PIL_TICK, with SCHED_ULE the execution of interrupts higher than
PIL_PREEMPT may be migrated to another CPU. In particular, tl1_ret(),
which is responsible for restoring the state of the CPU prior to entry
to the interrupt based on the (also migrated) trap frame, then is run
on a CPU which actually didn't receive the interrupt in question,
causing an inappropriate processor interrupt level to be "restored".
In turn, this causes interrupts of the first level, i.e. PIL_ITHREAD
in the above scenario, to be blocked on the target of the migration
until the correct PIL happens to be restored again on that CPU again.
Making PIL_PREEMPT the lowest real priority, this effectively prevents
this scenario from happening, as preemption interrupts no longer can
interrupt any other interrupt besides stray ones (which is no issue).
Thanks to attilio@ and especially mav@ for helping me to understand
this problem at the 201208DevSummit.
- Give PIL_STOP (which is also used for IPI_STOP_HARD, given that there's
no real equivalent to NMIs on SPARC v9) the highest possible priority
just below the hardwired PIL_TICK, so it has a chance to interrupt
more things.
