- Use FBSDID in trap.c
- Make the global trap_sig[] static as it's not used outside of trap.c.
- In sendsig() remove an unused variable.
- In trap() sync with the other archs; for fast data access MMU miss and
data access protection traps set ksi_addr to the SFAR reg which contains
the faulting address and otherwise to the TPC reg. Generally the TCP reg
contains the address of the instruction that caused the exception, except
for fast instruction access traps (and some others; more refinement may
be needed here) it also contains the faulting address.
Previously sendsig() always set si_addr to the SFAR reg which is wrong
for most traps.
- In sendsig() add support for FreeBSD old-style signals.
These changes are inspired by kmacy's sun4v changes and allow libsigsegv
to build on FreeBSD/sparc64, but it doesn't pass all checks and tests it
actually should, yet.

in the commit log) submitted support for some NO_* knobs for delete-old*
and check-old. I converted it to the new WITHOUT_* knobs (more correctly:
MK_*) and added some dummy ones so that people can see what's missing.
Volunteers can have a look at http://phk.freebsd.dk/misc/build_options/
for a list of files.
The location looks a little bit odd to me, but I don't care about the
color of this bikeshed and follow the suggestion of our build
infrastructure guru to place it "somewhere under src/tools/ please". [1]
The build/mk/ directory looks more sane to me than the other ones there.

intr_disable() and intr_restore() resp. Previously, critical
regions would have interrupts disabled, but that was changed.
Consequently, the debugger could run with interrupts enabled.
This could cause problems for the low-level console code where
received characters would trigger an interrupt that causes
the interrupt handler to read the character instead of the
cngetc() function.
The INP_DROPPED check replaces the current NULL checks; the INP_TIMEWAIT
checks appear to have always been required, but not been there, which
is/was a bug. This avoids unconditionally casting of in_ppcb to a tcpcb,
when it may be a twtcb, which may have resulted in obscure ICMP-related
panics in earlier releases.

Consistently use intotw() to cast inp_ppcb pointers to struct tcptw *
pointers.
Consistently use intotcpcb() to cast inp_ppcb pointers to struct tcpcb *
pointers.
Don't assign tp to the results to intotcpcb() during variable declation
at the top of functions, as that is before the asserts relating to
locking have been performed. Do this later in the function after
appropriate assertions have run to allow that operation to be conisdered
safe.

immediately rather than jumping to the normal output handling, which
assumes we've pulled out the inpcb, which hasn't happened at this
point (and isn't necessary).
Return ECONNABORTED instead of EINVAL when the inpcb has entered
INP_TIMEWAIT or INP_DROPPED, as this is the documented error value.
This may correct the panic seen by Ganbold.

a pv entry if the number of entries is below the high water mark for pv
entries.
Use pmap_try_insert_pv_entry() in pmap_copy() instead of
pmap_insert_entry(). This avoids possible recursion on a pmap lock in
get_pv_entry().
Eliminate the explicit low-memory checks in pmap_copy(). The check that
the number of pv entries was below the high water mark was largely
ineffective because it was located in the outer loop rather than the
inner loop where pv entries were allocated. Instead of checking, we
attempt the allocation and handle the failure.

The following bug was just identified in OpenBSD and it looks like the same
bug exists in the other BSDen NFS servers.
A Linux client (don't know which version, but you can look at
http://bugzilla.kernel.org/show_bug.cgi?id=6256)
does a Setattr of mtime to the server's time, where the file is mode 0664 and
the client user has group access (ie. caller is not the file owner).
The BSD servers fail the Setattr with EPERM, since the VA_UTIMES_NULL flag
isn't set before doing the VOP_SETATTR.
It seems to me that this should be allowed, since it is allowed for a local
utimes(2). If so, the fix is to set VA_UTIMES_NULL for the
"set-time-to-server-time" cases of setting atime and/or mtime.

socket can have a tcp connection that has entered time wait
attached to it, in the event that shutdown() is called on the
socket and the FINs properly exchange before close(). In this
case we don't detach or free the inpcb, just leave the tcptw
detached and freed, but we must release the inpcb lock (which we
didn't previously).
