3cb7a24bec Make descriptor access and file allocation cheaper in many cases, 
mostly by avoiding a bunch of atomic operations.

f0545a5e5b - Add lwp_pctr(), get an LWP's preemption/ctxsw counter. 
- Fix a preemption bug in CURCPU_IDLE_P() that can lead to a bogus
  assertion failure on DEBUG kernels.

and use them instead of various spl's in the zs.c's.

b808c7c6b8 Deja Vu: when preparing the initial trap frame for a new forked lwp, 
explicitly clear condition code. Otherwise we might catch a signal
(handlers are inherited from the parent) before we ever return to
userland. The current trapframe is converted into a ucontext and after
the signal handler returns, the lwp stays in userland and directly
uses the ucontext to return to the fork call.
Fixes PR 41302.

9cce088ba8 When displaying boot-time trip-register settings, shift to exclude

boot, and that's way too hot for any memory!

a94204e132 Delete wdactivate() and sdactivate(). They were no-ops, but as a 
side-effect of registering them, config_detach(9) cleared DVF_ACTIVE
before it called wddetach() or sddetach().  Even though sd(4)'s
detachment may have subsequently failed with EBUSY, we could not
begin new disk I/O on sd(4) because the device had been deactivated.

By analogy to sdstrategy(), test device_is_active() in wdstrategy()
and if it is false set b_errno to EIO instead of initiating new
disk I/O.

XXX We should decline more politely to start new I/O, since
XXX !device_is_active() may mean simply that the device is suspended.
XXX I suppose that EIO is safe as long as system suspension is
XXX all-or-nothing.
