to be instances where the kernel doesn't properly save and/or
restore it.
Use noupcall and nocompleted flags in the KSE mailbox. These
require kernel changes to work which will be committed sometime
later. Things still work without the changes.
Remove the general kse entry function and use two different
functions -- one for scope system threads and one for scope
process threads. The scope system function is not yet enabled
and we use the same function for all threads at the moment.
Keep a copy of the KSE stack for the case that a KSE runs
a scope system thread and uses the same stack as the thread
(no upcalls are generated, so a separate stack isn't needed).
This isn't enabled yet.
Use a separate field for the KSE waiting flag. It isn't
correct to use the mailbox flags field.
The following fixes were provided by David Xu:
o Initialize condition variable locks with thread versions
of the low-level locking functions instead of the kse versions.
o Enable threading before creating the first thread instead
of after.
o Don't enter critical regions when trying to malloc/free
or call functions that malloc/free.
o Take the scheduling lock when inheriting thread attributes.
o Check the attribute's stack pointer instead of the
attributes stack size for null when allocating a
thread's stack.
o Add a kseg reinit function so we don't have to destroy and
then recreate the same lock.
o Check the return value of kse_create() and return an
appropriate error if it fails.
o Don't forget to destroy a thread's locks when freeing it.
o Examine the correct flags word for checking to see if
a thread is in a synchronization queue.
Things should now work on an SMP kernel.
'a="b" c="d" at loc=1 on busN' properly set 'c' and process the rest of
the stirng. Before it would ignore everything after variable 'a'.
o Parse nomatch and other events differently. They are more different
than the code allowed for, so we weren't properly parsing nomatch
events. It appears this fixes some of the demand loading issues that
I was having with devd.

This is how it has always been done (before and after rc.d) but
I somehow failed to include it when I broke up network1.

ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.
Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.
FreeBSD 5.1-RELEASE and later:
- newfs(8) will now create UFS2 file systems unless UFS1 is specifically
requested (-O1). To do this, I just twiddled the Oflag default.
- sysinstall(8) will now select UFS2 as the default layout for new
file systems unless specifically requested (use '1' and '2' to change
the file system layout in the disk labeler). To do this, I inverted
the ufs2 flag into a ufs1 flag, since ufs2 is now the default and
ufs1 is the edge case. There's a slight semantic change in the
key behavior: '2' no longer toggles, it changes the selection to UFS2.
This is very similar to a patch David O'Brien sent me at one point, and
that I couldn't find.

Note that the tp register (r13) is reserved as the TLS pointer in
the same way that that gp register (r1) is reserved as the global
pointer. This implementation uses the tp register to point to the
thread structure used by the threads implementation. This is not
in violation with the runtime specification provided the TLS is
a fixed distance from the thread structure. This is only an issue
when code used the __thread keyword to create TLS. This is not
supported at the moment.
