aches as a read-only file. In a number of cases this has led to
compiles failing- usually due to some strange NFS drift which thinks
that the opt_ah.h in the compile directory is out of date wrt the
source it is copied from. When the copy is executed again, it fails
because the target is read-only. Oops. Modify the compile hooks
avoid this.

for unaligned faults was never getting used (and evidently doesn't
work), so ifdef out for now
Because accessing ID registers in rtl81x9 needs 32bit register access
and RL_IDR4/RL_IDR5 registers are reservered registers bzero() is
needed before copying ethernet address.
This fixes unaligned memory accesses panic in sparc64.

elimination pass in the GCC 4.1 optimiser breaks the non-compliant behavior
on which FreeBSD relied. This change brings FreeBSD up to date by switching
trap frames to being explicitly passed by reference.

passed by value (trap frames) as if they were in fact being passed by
reference. For better or worse, this incorrect behaviour is no longer
present in gcc 4.1. In this patch I convert all trapframe arguments to
be explicitly pass by reference. I also remove vm86_initflags, pushing
the very little work that it actually does up into vm86_prepcall.

- 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

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.

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.

- 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.
