2b11dfee8e sh: Add __dead2 to two functions that do not return.
Apart from helping static analyzers, this also appears to reduce the size of
the binary slightly.

57bfe0a9f8 Do not fork nfsiod directly from the vop methods. This causes LORs between
vnode lock and several locks needed during fork, like fd lock.

Instead, schedule the task to be executed in the taskqueue context. We
still waiting for the fork to finish, but the context of the thread
executing the task does not make real LORs with our vnode lock.

47047e3418 Revamp locking a bit. This fixes three problems:
* processes now can't go away while we are inserting probes (fixes a panic)
* if a trap happens, we won't be holding the process lock (fixes a hang)
* fix a LOR between the process lock and the fasttrap bucket list lock

Thanks to kib for pointing some problems.

b722ad008b Merge some SCHED_ULE features to SCHED_4BSD:
- Teach SCHED_4BSD to inform cpu_idle() about high sleep/wakeup rate to
choose optimized handler. In case of x86 it is MONITOR/MWAIT. Also it
will be needed to bypass forthcoming idle tick skipping logic to not
consume resources on events rescheduling when it won't give any benefits.
- Teach SCHED_4BSD to wake up idle CPUs without using IPI. In case of x86,
when MONITOR/MWAIT is active, it require just single memory write. This
doubles performance on some heavily switching test loads.

2c6d0e01f8 This patch applies one of the two fixes suggested by
zack.kirsch at isilon.com for a race between nfsrv_freeopen()
and nfsrv_getlockfile() in the experimental NFS server that
he found during testing. Although nfsrv_freeopen() holds a
sleep lock on the lock file structure when called with
cansleep != 0, nfsrv_getlockfile() could still search the
list, once it acquired the NFSLOCKSTATE() mutex. I believe
that acquiring the mutex in nfsrv_freeopen() fixes the race.

that it works correctly for ZFS file handles. It is possible to
have two ZFS file handles that differ only in the bytes in the
fid_reserved field of the generic "struct fid" and comparing the
bytes in fid_data didn't catch this case. This patch changes the
macro to compare all bytes of "struct fid".
