89f087e8dd Fix builds with a read-only directory and a make upgrade. This is done
by forcing the creation of an object directory for the make regression
tests. Let make handle the tracking of the dependency and installation
of test_shell script.

20a92a18f1 The remaining part of nmount/omount/rootfs mount changes. I cannot sensibly
split the conversion of the remaining three filesystems out from the root
mounting changes, so in one go:

cd9660:
	Convert to nmount.
	Add omount compat shims.
	Remove dedicated rootfs mounting code.
	Use vfs_mountedfrom()
	Rely on vfs_mount.c calling VFS_STATFS()

nfs(client):
	Convert to nmount (the simple way, mount_nfs(8) is still necessary).
	Add omount compat shims.
	Drop COMPAT_PRELITE2 mount arg compatibility.

ffs:
	Convert to nmount.
	Add omount compat shims.
	Remove dedicated rootfs mounting code.
	Use vfs_mountedfrom()
	Rely on vfs_mount.c calling VFS_STATFS()

Remove vfs_omount() method, all filesystems are now converted.

Remove MNTK_WANTRDWR, handling RO/RW conversions is a filesystem
task, and they all do it now.

Change rootmounting to use DEVFS trampoline:

vfs_mount.c:
	Mount devfs on /.  Devfs needs no 'from' so this is clean.
	symlink /dev to /.  This makes it possible to lookup /dev/foo.
	Mount "real" root filesystem on /.
	Surgically move the devfs mountpoint from under the real root
	filesystem onto /dev in the real root filesystem.

Remove now unnecessary getdiskbyname().

kern_init.c:
	Don't do devfs mounting and rootvnode assignment here, it was
	already handled by vfs_mount.c.

Remove now unused bdevvp(), addaliasu() and addalias().  Put the
few necessary lines in devfs where they belong.  This eliminates the
second-last source of bogo vnodes, leaving only the lemming-syncer.

Remove rootdev variable, it doesn't give meaning in a global context and
was not trustworth anyway.  Correct information is provided by
statfs(/).

993fd0c509 PNP BIOS devices are fundamentally different than ISA PNP devices.
These devices should be probed first because they are at fixed
locations and cannot be turned off.  ISA PNP devices, on the other
hand, can be turned off and often can be flexible in the resources
they use.  Probe them last, as always.

d461245f5d Switch from using an sx lock to a mutex for the mac_portacl rule chain:
the sx lock was used previously because we might sleep allocating
additional memory by using auto-extending sbufs.  However, we no longer
do this, instead retaining the user-submitted rule string, so mutexes
can be used instead.  Annotate the reason for not using the sbuf-related
rule-to-string code with a comment.

Switch to using TAILQ_CONCAT() instead of manual list copying, as it's
O(1), reducing the rule replacement step under the mutex from O(2N) to
O(2).

Remove now uneeded vnode-related includes.

ddc6c40075 2 fixes that improve on the consistency of the NFS client cache.
- Change the cached mtime to a 'struct timespec' from a
  time_t. Improving the precision of the cached mtime tightens up
  NFS' "close-to-open" consistency considerably.
- Always force an over-the-wire consistency check from nfs_open()
  (unless the file is marked modified). This further improves
  NFS' "close-to-open" consistency.

6a4b48f488 Convert msdosfs to nmount.
Add a vfs_cmount() function which converts omount argument stucture
to nmount arguments.

Convert vfs_omount() to vfs_mount() and parse nmount arguments.

This is 100% compatible with existing userland.

Later on, but before userland gets converted to nmount we may want
to revisit the names of the mountoptions, for instance it may make
sense to use consistent options for charset conversion etc.

d54d263a79 Serialize NFS vinvalbuf operations by acquiring/upgrading to the
vnode EXCLUSIVE lock. This prevents threads from adding pages to
the vnode while an invalidation is in progress, closing potential
races. In the bioread() path, callers acquire the SHARED vnode lock
- so while an invalidate was in progress, it was possible to fault
in new pages onto the vnode causing the invalidation to take a while
or fail. We saw these races at Yahoo! with very large files+heavy
concurrent access. Forcing an upgrade to EXCLUSIVE lock before doing
the invalidation closes all these races.

8fefdf0057 - If all data has been committed to stable storage on the server, it
is safe to turn off the nfsnode's NMODIFIED flag.
- Move the check for signals to the top of the loop where we loop
  around the dirty buffers on the vnode, scheduling writes. This
  ensures that we'll break ouf of the flush operation on reception of
  a signal.
