potential problems with other automatic-reply ICMPs, but some of them may
depend on broadcast/multicast to operate. (This code can simply be
moved to the `reflect' label to generalize it.)
Added a new variable, 'bsp_apic_ready', which is set as soon as the bootstrap
CPU has initialized its local APIC. Conditionalize the GENSPLR functions
to call ss_lock ONLY after bsp_apic_ready is TRUE; This should prevent
any problems with races between the time the 1st AP becomes ready and the
time smp_active is set.
doclusterread/doclusterwrite into ext2_doclusterread and
ext2_doclusterwrite, which are unique names. Moved #include of
<sys/sysctl.h> to the top of the file.

region protected by the simplelock 'cpl_lock'.
Notes:
- this code is currently controlled on a section by section basis with
defines in machine/param.h. All sections are currently enabled.
- this code is not as clean as I would like, but that can wait till later.
- the "giant lock" still surrounds most instances of this "cpl region".
I still have to do the code that arbitrates setting cpl between the
top and bottom halves of the kernel.
- the possibility of deadlock exists, I am committing the code at this
point so as to exercise it and detect any such cases B4 the "giant lock"
is removed.
- Do not malloc SCRIPTS memory for those parts of the microcode that
are to be loaded into the on-chip SRAM of the 53c825a or 875 ...
- Modify ncr_chip_lookup to make adding new entries easier.
- Disable use of on-chip SRAM for the 53c825 rev 0x10 to 0x12, since
there seems to be a problem with rev 0x11, while 0x13 is known to
work. (Tested by Chuck Robey <chuckr@glue.umd.edu>).
This code will be merged into 2.2-stable after a few more days of
testing in -current.
free list problem. Also, the vnode age flag is no longer used by the
vnode pager. (It is actually incorrect to use then.) Constructive
feedback welcome -- just be kind.
pause before attempting to reset the sequencer address. Remove the
loop checking to see if the address has gone to zero since it is
unnecessary
Adjust the abort SCB timeouts back up to 2 seconds where they should
be.
Fix an oversight in the removal of the bus reset settle code where
we might not run the queue of completed commands.
Remove an unecessary call to ahc_run_done_queue in ahc_reset_current_bus.

Made NEW_STRATEGY default.
Removed misc. old cruft.
Centralized simple locks into mp_machdep.c
Centralized simple lock macros into param.h
More cleanup in the direction of making splxx()/cpl MP-safe.
