- ptrace_single_step() is no longer called with the proc lock held, so
don't try to unlock it and then relock it.
- Push Giant down into proc_rwmem() instead of forcing all the consumers
(including Alpha breakpoint support) to explicitly wrap calls to
proc_rwmem() with Giant.

case where an /etc/nsswitch.conf file was present, but could not
be opened (e.g. due to permissions). Previously, the open failure
condition was suppressed, and the built-in defaults were used. In
revision 1.11, however, propagated the open failure causing all
nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs
including getpwnam and gethostbyname unconditionally failed.
This commit restores the previous behavior.

not quite well by me - if kern.ps_argsopen was set to 0, users weren't
permitted to see arguments of even own processes.
But kern.ps_argsopen is going away, so just remove this check and leave
security checks for p_cansee() function.
1. This check if wrong, because it is true by default
(kern.ps_argsopen is 1 by default) (p_cansee() is not even checked).
2. Sysctl kern.ps_argsopen is going away.
completely understand], md_takeroot() runs before md_preloaded(),
rendering both useless.
As a fix, move the body (effectively one line!) of md_takeroot()
into md_preloaded(), and get rid of the stuff that has become useless.
Bug and fix reported 10 days ago on -current, no reply.
the driver's RX ring head may fall behind the chip, causing the
stuck traffic, disordered packets, etc. Work around this by
adopting the technique of resyncing RX head used in dc(4) and
xl(4) drivers, but do it in a slightly different place to reduce
the number of resyncs needed.
Also, set the NIC's RX polling period to a more meaningful value,
to stop overloading the PCI bus (this also reduces the number of
resyncs by a factor of 3 or more in a long run; the actual number
is very dependent on a nature of the traffic).
Maintain the statistics counter as the hw.ste_rxsyncs sysctl.

present in ndp(8).
The vendor branch import uses a _U_ macro to apply the GCC 'unused' attribute
to the rcs ids embedded in each source file. Teach ndp about this.
pcap should not fall back to its own implementations in the absence of
HAVE_SNPRINTF and HAVE_VSNPRINTF defines when compiled and installed
as part of the world. This should fix builds of pflogd and packages
depending on the base system libpcap.

print-atm.c no longer performs special handling for FORE headers; these
can no doubt be re-added at a later date.
print-fr.c is effectively a no-op.
print-llc.c has had the default_print_unaligned() call removed as
tcpdump no longer defines this function, however the prototype is still
present. Suggest we roll in a diff to use print_unknown_data().
they all do and handle that without alarming the user. Also pull in a bit
of defensive code from OpenBSD that triggers when a card is recognised but
not properly classified as either Genesis or Yukon. Not that I could ever
have needed this. :-)
