Erwin fired up a ports build a couple of weeks ago and it seems the
following functions are not used by any of the 20k ports we have, which
makes me believe they don't have any purpose. Just remove them.
IPI to a specific CPU by its cpuid. Replace calls to ipi_selected() that
constructed a mask for a single CPU with calls to ipi_cpu() instead. This
will matter more in the future when we transition from cpumask_t to
cpuset_t for CPU masks in which case building a CPU mask is more expensive.

interfaces to be a vlan (IFT_L2VLAN) rather than an Ethernet interface
(IFT_ETHER). The code already fixed if_type in the ifnet causing some
places to report the interface as a vlan (e.g. arp -a output) and other
places to report the interface as Ethernet (getifaddrs(3)). Now they
should all report IFT_L2VLAN.

interfaces like IFT_ETHER interfaces when handling link layer addresses.

cdev will never be destroyed. Propagate the flag to devfs vnodes as
VV_ETERNVALDEV. Use the flags to avoid acquiring devmtx and taking a
thread reference on such nodes.

MIPS doesn't really need to use atomic_cmpset_int() in situations like
this because the software dirty bit emulation in trap.c acquires
the pmap lock. Atomics like this appear to be a carryover from i386
where the hardware-managed TLB might concurrently set the modified bit.

pmap_page_wired_mappings() counts the number of pv entries for the
specified page that have the pv entry wired flag set to TRUE.
pmap_enter() correctly initializes this flag. However,
pmap_change_wiring() doesn't update the corresponding pv entry flag,
only the PTE. So, the count returned by pmap_page_wired_mappings()
will sometimes be wrong.
In the short term, the best fix would be to eliminate the pv entry
flag and use only the PTE. That flag is wasting non-trivial memory.
Remove pv_wired flag, and use PTE flag to count the wired mappings.
