to dup_sockaddr() was renamed to sodupsockaddr(), the argument was
changed from '1' to 'M_WAITOK', which changed the semantics. This
resulted in a WITNESS warning about a potential sleep while holding the
NFS server mutex. Now this will no longer happen, restoring a possible
bug present in the original code (setting RC_NAM even though the malloc
to copy the addres may fail). bde observes that the flag names here
should probably not be the same as the malloc flags for name space
reasons.

honor the alignment and boundary constraints in the dma tag when loading
buffers. Previously, these constraints were only honored when allocating
memory via bus_dmamem_alloc(). Now, bus_dmamap_load() will automatically
use bounce buffers when needed.
Also add a set of sysctls to monitor the global busdma stats. These are:
hw.busdma.free_bpages
hw.busdma.reserved_bpages
hw.busdma.active_bpages
hw.busdma.total_bpages
hw.busdma.total_bounced
hw.busdma.total_deferred
to failing -- that is, allocations via malloc(M_WAITOK) that are required
to never fail -- if WITNESS is not defined. While everyone should be
running WITNESS, in any case, zone "Mbuf" allocations are really the only
ones that should be screwed with by this hack.
This hack is crashing people, and would continue to do so with or without
WITNESS. Things shouldn't be allocating with M_WAITOK with locks held,
but it's not okay just to always remove M_WAITOK when !WITNESS.

FAT32 filesystems to be mounted, subject to some fairly serious limitations.
This works by extending the internal pseudo-inode-numbers generated from
the file's starting cluster number to 64-bits, then creating a table
mapping these into arbitrary 32-bit inode numbers, which can fit in
struct dirent's d_fileno and struct vattr's va_fileid fields. The mappings
do not persist across unmounts or reboots, so it's not possible to export
these filesystems through NFS. The mapping table may grow to be rather
large, and may grow large enough to exhaust kernel memory on filesystems
with millions of files.
Don't enable this option unless you understand the consequences.
- Remove recursive locking situations. Remove the MTX_RECURSE bit.
- Take the lock for any routine which is not called from within if_vr.c
itself; this includes entry points called by newbus, ifnet, callout,
ifmedia, and polling subsystems.
- Remove spl references from the code added to miibus callbacks in rev 1.60.
- Add the INTR_MPSAFE bit.
- Tidy up some assignments; locks are not needed for taking the address
of something at a known offset, for example.
- Tested on the machine this was committed from.
Tested on: UP only, !debug.mpsafenet && debug.mpsafenet

introduced a KSE_CAN_MIGRATE() invocation with one argument
missing (class). Either this is a genuine forget or it crept
in from JHB's repo where he may have modified it. If it's
the latter then it may require more attention. For now fix
the make depend.
Put some braces around the busy-wait loop in vr_rxeoc() to make the
no-op semicolon more obvious.
No functional changes.
Running on the machine I am committing from without problems.
