reason to inline the implementation of vm_page_lock_assert() in the
!KLD_MODULES case. Use the same implementation for both KLD_MODULES and
!KLD_MODULES.

In most shells (including our sh), break outside a loop does nothing with
status 0, or at least does not abort. Therefore, scripts sometimes (buggily)
depend on this.
- Use a shared bufobj lock in getblk() and inmem().
- Convert softdep's lk to rwlock to match the bufobj lock.
- Move INFREECNT to b_flags and protect it with the buf lock.
- Remove unnecessary locking around bremfree() and BKGRDINPROG.

The option tells kdump to convert numeric UIDs and GIDs into user and
group names plus to convert times and dates into locallized versions.
This all needs opening various files at various occasions.
they are needed when porting some of the Solaris providers (ip, iscsi, and
tcp in particular).
dtrace_probe() only takes five arguments from the probe site, so we need to
add the appropriate cast to allow for more than five arguments. The extra
arguments are later copied out of dtrace_probe()'s stack frame by
dtrace_getarg() (or the provider-specific getarg method) as needed.

Actually, this may be further optimized for controller variants
supporting one-shot MSIs but I'm lacking the necessary hardware for
testing.
- Add some missing synchronization of the statistics and status DMA
maps.

execute the further code which assumes that ref_count == 1 if it is
not. Also, do not leak vnode lock if other thread cleared OBJ_TMPFS
flag meantime.

- Honor errors passed to the DMA mapping callbacks.
- In bce_get_rx_buf(), do not reserve stack space for more DMA segments
than actually necessary.
- In bce_get_pg_buf(), take advantage of bus_dmamap_load_mbuf_sg(9).
- In bce_rx_intr(), remove a pointless check for an empty mbuf pointer
which can only happen in case of a severe programming error. Moreover,
recovering from that situation would require way more actions with header
splitting enabled (which it is by default).
- Fix VLAN tagging in the RX path; do not attach the VLAN tag twice if the
firmware has been told to keep it. [1]

- Replace an outdated and now bogus comment in bce_tick() with the
appropriate one.

- the VALE switch now support up to 254 destinations per switch,
unicast or broadcast (multicast goes to all ports).
- we can attach hw interfaces and the host stack to a VALE switch,
which means we will be able to use it more or less as a native bridge
(minor tweaks still necessary).
A 'vale-ctl' program is supplied in tools/tools/netmap
to attach/detach ports the switch, and list current configuration.
- the lookup function in the VALE switch can be reassigned to
something else, similar to the pf hooks. This will enable
attaching the firewall, or other processing functions (e.g. in-kernel
openvswitch) directly on the netmap port.
The internal API used by device drivers does not change.
Userspace applications should be recompiled because we
bump NETMAP_API as we now use some fields in the struct nmreq
that were previously ignored -- otherwise, data structures
are the same.
Manpages will be committed separately.
