because nothing uses this new feature and doing so forces everybody to
recompile for no good reason. This chnage will be MFC'd where the

are the only two that have use the option remapping feature. Once
merged, this will give a better error message to folks that are using

Assert this.
In the reported panic, vdestroy() fired the assertion "vp has namecache
for ..", because pseudofs may end up doing cache_enter() with reclaimed
dvp, after dotdot lookup temporary unlocked dvp.
Similar problem exists in ufs_lookup() for "." lookup, when vnode
lock needs to be upgraded.
Verify that dvp is not reclaimed before calling cache_enter().

This will prevent the function that acquires stateids for I/O

Also, fix up mutex locking on the nfsc_flags field.

When performing a smp_rendezvous() or more likely, on amd64 and i386,
a smp_tlb_shootdown() the caller will end up with the smp_ipi_mtx
spinlock held, busy-waiting for other CPUs to acknowledge the operation.
As long as CPUs are suspended (via cpu_reset()) between the active mask
read and IPI sending there can be a deadlock where the caller will wait
forever for a dead CPU to acknowledge the operation.
Please note that on CPU0 that is going to be someway heavier because of
the spinlocks being disabled earlier than quitting the machine.
Fix this bug by calling cpu_reset() with the smp_ipi_mtx held.
Note that it is very likely that a saner offline/online CPUs mechanism
will help heavilly in fixing similar cases as it is likely more bugs
of this type may arise in the future.
