functions, they are unused. Remove 'user' from npxgetuserregs()
etc. names.
For {npx,fpu}{get,set}regs(), always use pcb->pcb_user_save for FPU
context storage. This eliminates the need for ugly copying with
overwrite of the newly added and reserved fields in ucontext on i386
to satisfy alignment requirements for fpusave() and fpurstor().
pc98 version was copied from i386.

implement supporting multi-queue. Allocating more than necessary
vectors is resource waste and it can be added back when we
implement multi-queue support.
number of retry to be performed whenever controller found RX
descriptor was empty. RX empty interrupt is generated only when the
retry counter is over. Experimentation shows retrying RX descriptor
loading increased number of dropped frames under flow-control

empty interrupt as fast as it can.

updates were being queued by pmap_kremove, but the queue wasn't being
flushed; as a result, the updates didn't happen until *after* the call
to pmap_invalidate_range, and old entries could stick around in the TLB.
Adding a PT_UPDATES_FLUSH() call immediately before pmap_invalidate_range
ensures that after the invalidation the TLB will be repopulated with the
correct new entries.

actually work, linking of libgcc_s.so.1 on ia64 will fail with:
unwind-ia64.So(.text+0x1762): In function `_Unwind_FindEnclosingFunction':
: undefined reference to `_Unwind_FindTableEntry'

/usr/bin/ld: libgcc_s.so.1: hidden symbol `_Unwind_FindTableEntry' isn't defined
Repair this by not hiding the _Unwind_FindTableEntry symbol; on FreeBSD,
it is in libc, not in libgcc.

the TLB which don't correspond to ptes with PG_V set; prior to this commit
I'm sometimes getting the wrong data when pages are loaded into the buffer
cache (they're being loaded, but the missing TLB invalidation is causing
the wrong data to be visible).

to provide serialization of calls into the node, which is accomplished
by markng the node as single-threaded (NGF_FORCE_WRITER).
The price we pay is that each ng_pipe instance now has its own callout
handler which polls for queued frames on each clock tick, as long as
the pipe has any frames in its internal queues. OTOH, we got rid of
the global ng_pipe mutex, so from now on multiple ng_pipe instances
can operate in parallel. This change also fixes counting of forwarded
frames when an ng_pipe node is not enforcing any packet impairments.
While here, attempt to improve adherance to style(9) throughout
otherwise mostly unreadable code.

When shared-locked vnode is supplied as an argument to vunref(9) and
resulting usecount is 0, set VI_OWEINACT and do not try to upgrade vnode
lock. The later could cause vnode unlock, allowing the vnode to be
