This fixes a rather curious forwarding/redirect/etc. storm which
happened when there were >2 shmif kernels on the same shmbus with
ip forwarding set on. (at least it stress-tested other code ;)
appears that using nxr to search for users wasn't a very good idea.
Put networking back and make the test of the defines give out

the exec handshake to return.
In addition to being The Right Thing To Do, fixes some nasty
conditions for CLOEXEC fd's (or at least does so in theory, I
couldn't create any problems although I tried).
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

return false. This makes rump lfs unmount work on platforms which
use the pmap stub (i.e. non-x86, which already returned false here).
Otherwise, lfs would hang itself trying to flush some buffers but
couldn't fill a segment and therefore wouldn't actually write
anything.
Fixes nfs{,ro}_fileio tests on at least sparc64 (and probably macppc
and other fat endian machines).
The problem was that nfs was fooled to thinking read() caused a
write fault because of VM_PROT_WRITE being unconditionally set and
therefore set NMODIFIED on a r/o file system. It is absolutely
beyond me why the test worked on i386/amd64. Incidentally, I seem
to have "misplaced" a few goats.
in tmpfs_node), so when playing with pages make sure we lock the
uvm object the pages belong to instead of the vnode's uvm object.
per test from Nicolas Joly (which I'm sure he will commit soon ;)
pageouts active and give up only if the pagedaemon could not free
memory and there are no outstanding pageouts.
This should fix the "out of memory" pauses reported by Mihai Chelaru
and Taylor R Campbell. Tested by copying files to and from an ffs
backed by /dev/wd0 (with and without -o log) using a 1MB rump kernel
memory limit.
of p_start/endzero for whatever reasons.
Obviously, this fixes remote physio when running with MALLOC_OPTIONS J.
Otherwise PS_WEXIT is set in struct proc, proc_vmspace_getref() fails,
and copyout_proc() with it.

every time the virtual device is opened. this takes care of e.g.
a midlife chmod crisis

host offset. otherwise we might end up in a situation with 0

to open(), which act just like lookups if the node exists (found
from etfs). If the node doesn't exist in etfs, nothing changes
from the previous situation.
