545ea86459 OpenPAM allows passing a NULL "pamh" to pam_strerror() to indicate
that the creation of a PAM context has failed.

N.B. This does not apply to pam_strerror() in RELENG_4, it
will mishandle a NULL "pamh".

6d25ea1fa6 Replace link to nonexistent raid(4) with one to geom(8). I don't like
implying that geom(8) is a RAID solution, but it can be used for that
purpose, and a pointer in that direction is better than nothing.

d88642fe52 Remove the -k option to migrate. The option causes gpt(8) to preserve
the MBR after it is migrated to a GPT. While this was useful during
the early days when GPT support was under development, it's something
that users can use without knowing what they're getting themselves
into. The possible harm outweights the marginal usefulness it now has.

a1107cc375 Don't barf when we encounter an UUID for GPT partitions. Instead, add
the GPT partition on i386 and adm64 as type=gpt, subtype=0 and with the
sname set to the UUID. This prevents sysinstall from bombing out. This
also makes sure the GPT partition shows up in sysinstall so as to avoid
accidental "clobberage".

303a718c5e With ALTQ, it is possible that although the queue was not empty when we
entered the interface start function, no packets were actually dequeued.
Therefore, keep a count of how many packets we really added onto the tx
chain, and initiate a transmit only if the count is non-zero.

1e4cadcb14 Disable use of synchronization early in the boot by the MAC Framework;
for modules linked into the kernel or loaded very early, panics will
result otherwise, as the CV code it calls will panic due to its use
of a mutex before it is initialized.

923a1dc3d1 Add a loader menu option to set hint.atkbd.0.flags=0x1 which allows USB
keyboards to work if no PS/2 keyboard is attached.  The position in the
menu was chosen to avoid moving option 6 (loader prompt).  This should

0516c8dd4a - When choosing a thread on the run queue, check to see if its nice is
outside of the nice threshold due to a recently awoken thread with a
   lower nice value.  This further reduces the amount of time a positively
   niced thread gets while running in conjunction with a workload that has
   many short sleeps (ie buildworld).

6bd0c7fd53 - In sched_prio() check to see if the kse is assigned to a runq as the
check for TD_ON_RUNQ() no longer means the thread is really on a run-

   something else now.  This fixes ULE+KSE+PREEMPTION on UP x86.
