remove the check from addupc_task(). It would need sched_lock while
testing the flag anyways.
- Always read sticks while holding sched_lock using a temporary variable
where needed.
- Always init prticks to 0 in ast() to quiet a warning.
sense, and mode select into their 10 byte equivalents. Eventually the
da(4) driver will become more intelligent about this, or at least allow
umass(4) to pass quirks in directly. However, this is a functional
workaround until a better fix is implemented.
- Use the 6 to 10 conversion function to allow the ATAPI and UFI command
sets to emulate 6 byte commands with 10 byte commands.
- Use the ATAPI command set rather than UFI for the ScanLogic SL11R-IDE
as it supports the SYNCH_CACHE command.
- Enable ATAPI command set support.
- Pass READ/WRITE_12 commands through for UFI support as the UFI spec
says they should be supported.
- Update a comment in the UFI translation function since we handle
MODE_SELECT.
temporary storage. In the old NFS code it wasn't at all clear if
the value of `tl' was used across or after macro calls, but I'm
fairly confident that the convention was to keep its use local.
Each ex-macro function now uses a local version of this variable,
so all of the double-indirection goes away.
The only exception to the `local use' rule for `tl' is nfsm_clget(),
which is left unchanged by this commit.

- The MD functions critical_enter/exit are renamed to start with a cpu_
prefix.
- MI wrapper functions critical_enter/exit maintain a per-thread nesting
count and a per-thread critical section saved state set when entering
a critical section while at nesting level 0 and restored when exiting
to nesting level 0. This moves the saved state out of spin mutexes so
that interlocking spin mutexes works properly.
- Most low-level MD code that used critical_enter/exit now use
cpu_critical_enter/exit. MI code such as device drivers and spin
mutexes use the MI wrappers. Note that since the MI wrappers store
the state in the current thread, they do not have any return values or
arguments.
- mtx_intr_enable() is replaced with a constant CRITICAL_FORK which is
assigned to curthread->td_savecrit during fork_exit().

- Axe inlvtlb_ok as it was completely redundant with smp_active.
- Remove references to non-existent variable and non-existent file
in i386/include/smp.h.
- Don't perform initializations local to each CPU while holding the
ap boot lock on i386 while an AP bootstraps itself.
- Reorganize the AP startup code some to unify the latter half of the
functions to bring an AP up. Eventually this might be broken out into
a MI function in subr_smp.c.

For future reference, the bug was in our code, and not
some bug in the 3com chips.
