but then parked ourselves in real mode without completing acquisition of
said lock. Also removes the park routine from i386 since we don't need it
(the APs are already parked at the time we start unpack).

the various bpf_mtap_* are very similiar, they differ in what (and to some
extent how) they prepend something, and what copy function they pass to
bpf_catchpacket.
use an internal _bpf_mtap as "backend" for bpf_mtap and friends.
extend bpf_mtap_hdr so that it covers all common cases:
if dlen is 0, nothing gets prepended.
copy function can be given, if NULL the default bpf_mcopy is used.
adjust the existing bpf_mtap_hdr users to pass a NULL ptr for the copy fn.
re-implement bpf_mtap_af as simple wrapper for bpf_mtap_hdr.
re-implement bpf_mtap_ether using bpf_map_hdr
re-implement bpf_mtap_pflog as trivial bpf_mtap_hdr wrapper

but I flipped the test on i386/amd64, thus breaking kernel traps before
enough proc0 bits were set up. In theory, this could have resulted in
a NFS read for a page fault being done with a process's old credentials.

While there, tweak stack argument fetching to only perform one large copyin()
call, rather than a loop of small ones.

add any sort of locking to the pool code we need that working. Found out the

with the exponent sign-extended to the double-precision exponent width.
Make sure we shrink it and fetch the remaining three low bits of mantissa from
the LS registers.

denormal results) with C code using softfloat to correctly round the inexact
results in the best possible way according to the current rounding mode.
No functional change intended, and this assembly code was surprisingly almost
non-buggy, as opposed to the precise exception code replaced a few weeks ago;
still an improvement as this replaces 900 lines of arcane assembly with 90
lines of understandable C code.

While there, make sure every runtime printf is prefixed by either the complete
target information, if available, or at least the driver name with the
proper instance number - supported systems with > 1 wdsc are quite common.
