and sent to the DIVERT socket while the original packet continues with the
next rule. Unlike a normally diverted packet no IP reassembly attemts are
made on tee'd packets and they are passed upwards totally unmodified.
Note: This will not be MFC'd to 4.x because of major infrastucture changes.

doesn't do this is beyond me, but that will be investigated later. This
results in programming the chip with the correct frequency, which in turn
allows devices to negotiate up to the full 20MB/s.
and the previously malloc'ed snapshot lock.
Malloc struct snapdata instead of just the lock.
Replace snapshot fields in cdev with pointer to snapdata (saves 16 bytes).
While here, give the private readblock() function a vnode argument
in preparation for moving UFS to access GEOM directly.
preparation for integration of p4::phk_bufwork. In the future,
local filesystems will talk to GEOM directly and they will consequently
be able to issue BIO_DELETE directly. Since the removal of the fla
driver, BIO_DELETE has effectively been a no-op anyway.
the loss of a page modified (PG_M) bit in a race between processors.
Quoting Tor:
One scenario where the old code could cause a lost PG_M bit is a
multithreaded linux program (or FreeBSD program using the
linuxthreads port) where one thread was starting a subprocess.
The thread doing fork() would call vmspace_fork(), which would then
call vm_map_copy_entry() which would call pmap_protect() on an area
possibly accessed by other threads.
Additionally, make the clearing of PG_M by pmap_protect() unconditional if
write permission is removed. Previously, PG_M could persist on a read-only
unmanaged page. That seems inconsistent and confusing.
