The different between the new function and g_mirror_orphan() (which was
used previously) is that syncid is bumped immediately, instead of on
first write, because when consumer was spoiled, it means, that its
provider was opened for writing, so we can't trust that its data
will be valid when it will be connected again.

It is not a mere issue of style: Null pointers in C
seem to have been mistaken one way or another quite often.

Name our filesystems mount function consistently.
Eliminate the namiedata argument to both vfs_mount and vfs_omount.
It was originally there to save stack space. A few places abused
it to get hold of some credentials to pass around. Effectively
it is unused.
Reorganize the root filesystem selection code.

- Eliminate the acquisition and release of Giant from vm_map_protect().
(Translation: mprotect(2) runs to completion without touching Giant on

brings ia64 to parity with alpha, amd64, and i386 in this area.)
- Prevent a race in pmap_find_pte(): If pmap_find_pte() sleeps in
uma_zalloc(), another thread could allocate a pte at the same address.
Instead, sleep at a higher level and retry the lookup before retrying
the allocation.

This is really ugly way to do this, but there is no other way for now.
It allows to mount root file system from providers which belong to

than one interface from the command line:
# /etc/rc.d/netif start bfe0 xl0
It's also possible to restart an interface(s):
# /etc/rc.d/netif restart bfe0
This required some changes to rc.subr(8) so that if the start/stop commands
are overidden the rest of the command line (after the start/stop/etc... cmd)
is passed through to the subroutines.
