pmap_ts_referenced().
Consolidate identical code for pmap_is_modified() and
pmap_is_referenced() into helper pmap_page_test_mappings().

Austin Group issue #411 requires 'e' to be accepted before and after 'x',
and encourages accepting the characters in any order, except the initial
'r', 'w' or 'a'.
Given that glibc accepts the characters after r/w/a in any order and that
diagnosing this problem may be hard, change our libc to behave that way as
well.
add some packet(s) to tx ring and arge_stop() is called before receive the
sent packet interrupt from hardware. Fix arge_stop() to unload the in use
dma tags and free the associated mbuf.

These are weak and so can be replaced by other versions in applications
that choose to do so, and will give a linker warning when used so that
applications that rely on the extra precision can avoid them.
Note that since the C/C++ specs only guarantee that long double has
precision equal to double, code that actually relies on these functions
having greater precision is unportable at best and broken at worst.
sf_buf_alloc()/sf_buf_free() inlines, to save two calls to an absolutely

This avoids closing down an entire build on failure of one branch.

krpc client side UDP was observed as way out of range and
caused the rpc.lockd daemon to hang trying to do an RPC.
Inspection of the code found two places where the RPC request
is re-queued, but the value of cu_sent was not incremented.
Since cu_sent is always decremented when the RPC request is
dequeued, I think this could have caused cu_sent to go out of
range. This patch adds lines to increment cu_sent for these
two cases.

Record the initial state earlier, so it is always safe to restore it.
One way this happens is if watch(8) is started by a user that does not have
access to /dev/snp. The result is "staircase effect" during later commands.
