6764eb8e7b Warning fix. (Very basic - add the right include so that rdtsc() gets 
a prototype).

f4e18c9afd Fix a minor swap leak. 
Previously, the UPAGES/KSTACK area of processes/threads would leak memory
at the time that a previously swapped process was terminated.  Lukcily, the
leak was only 12K/proc, so it was unlikely to be a major problem unless you
had an undersized swap partition.

54eb8bbc14 Remove most of the usage of critical_enter/exit. 
I put these in to match the use of spl*() in the NetBSD code I was basing this
on, but it appears to cause problems.

I'm doing this in a separate commit so as to be able to refer back if locking
becomes an issue at a later stage.

Define the atm_dev_free() routine so that its OK to free stuff that is defined
as volatile. Note this doesn't FORCE the arguemnts to be volatile,
just says that it's not an error if it is..

fdcc1cc09f Use thread0.td_ucred instead of proc0.p_ucred. This change is cosmetic 
and isn't strictly required.  However, it lowers the number of false
positives found when grep'ing the kernel sources for p_ucred to ensure
proper locking.

566c1313a3 add assertions in the places where giant is required to catch when 
the pipe is locked and shouldn't be.

initialize pipe->pipe_mtxp to NULL when creating pipes in order not
to trip the above assertions.

65e3406d28 Temporarily lock Giant while we update td_ucred. The proc lock doesn't 
fully protect p_ucred yet so Giant is needed until all the p_ucred
locking is done.  This is the original reason td_ucred was not used
immediately after its addition.  Unfortunately, not using td_ucred is
not enough to avoid problems.  Since p_ucred could be stale, we could
actually be dereferencing a stale pointer to dink with the refcount, so
we really need Giant to avoid foot-shooting.  This allows td_ucred to
be safely used as well.
