- The PCPU usage was to ensure that there were no faults on the stack while
the tte_hash_bucket lock was held - but this can be avoided by making sure
the address on the stack is already referenced.
- PCPU removal obviates the need for critical_{enter, exit}
- in trying to avoid nested brackets and #ifdef INVARIANTS around i at the
top, I broke booting for INVARIANTS all together :-(
- the cleanest fix is to simply assign to sq twice if INVARIANTS is enabled
- tested both with and without INVARIANTS :-/
after we perform the operations to delete the export,
call vfs_deleteopt() to delete the "export" mount option from
the linked list of mount options associated with that mount point.
This fixes one scenario:
- put a filesystem in /etc/exports to export it
- remove the filesystem from /etc/exports to delete the export and restart
mountd
- try to do a "mount -u -o ro" or "mount -u -o rw" on that filesystem
now that it is no longer exported.
arguments to fail. The mode field for shmget() appears to have undefined
meaning in the context of an already-present IPC object, but applications
appear to assume any arbitrary passed value will be ignored. I had hoped
to revisit this more quickly, but am removing the change for now to
prevent toe-stubbing.

- rename skip_utrap to tl0_skip_utrap to indicate its use by the fill trap fault handler
- handle a null kstack by switching to the idle threads stack and then going to trap
- correctly handle a unaligned or unmapped stack during a fill trap
- save off some extra data in the pcpu pad in ptl1_panic
- add an assert that PCB is valid in vm_machdep.c
- add cnt_hold cnt_lock support for spin mutexes
- make sure contested is initialized to zero to only bump contested when appropriate
- move initialization function to kern_mutex.c to avoid cyclic dependency between
mutex.h and lock_profile.h
behave as expected.
Also:
- Return an error if WD_PASSIVE is passed in to the ioctl as only
WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an
explanation of the difference between WD_ACTIVE and WD_PASSIVE.
- Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've
lost your sense of humor, than don't add a define.
Specific changes:
i80321_wdog.c
Don't roll your own passive watchdog tickle as this would defeat the
purpose of an active (userland) watchdog tickle.
ichwd.c / ipmi.c:
WD_ACTIVE means active patting of the watchdog by a userland process,
not whether the watchdog is active. See sys/watchdog.h.
kern_clock.c:
(software watchdog) Remove a check for WD_ACTIVE as this does not make
sense here. This reverts r1.181.
SNMP option argument. That way the compiler will give a warning in
case of a missing or an extra but unknown 'case:'.
Do the same for SNMP LEAF objects to be prepared once gensnmptree will
auto-generate enums for those too.
Add an abort() after the switch() instead of the 'default:' to catch
any errors. The nice side effect is that the compiler will correctly
track supposed to be 'uninitialized' variables with that.
When trying to set a value sanity check it before calling the OS
dependent API of snmp_bridge to tell whether it is an attempt to
set a bad value or a general error.

in the PR by removing spurious .HP tags, thereby actually
allowing the commands to show up in the man page output,
and making the style consistent with the nslookup(1) man
page. [1]
While I'm here, fix the markup on the first command reference
in nslookup(1).
