0229106442 Exchange whole structures on SUNIT, not unit+flags fields only. 
It is needed because if_attach() assumes fixed units order
and pass it to ifconfig

ffd8332856 Ignore the block size returned by scsi_read_capacity(): this value is 
rarely correct and the block size is already specified in the prepare_track()
functions.

f9e8dbb8c3 mpapic.c & mp_machdep: 
- removed TEST_ALTTIMER.
 - removed APIC_PIN0_TIMER.
 - removed TIMER_ALL.

mplock.s:
 - minor update of try_mplock for new algorithm where a CPU uses try_mplock
	instead of get_mplock in the ISRs.

12084b3cf1 clock.c: 
- removed TEST_ALTTIMER.
 - removed APIC_PIN0_TIMER.
 - removed TIMER_ALL.

apic_vector.s:
 - new algorithm where a CPU uses try_mplock instead of get_mplock:
	if successful continue as before.
	if fail set ipending bit, mask INT (to avoid recursion), cleanup & iret.

   This allows the CPU to return to successful work, while the ISR will be run
   by the CPU holding the lock as part of the doreti dance.

7f6ab10763 Removed the defunct GET_MPLOCK/REL_MPLOCK macros. 
These are no-ops for UP, and should have been removed when vector.s
was split into UP and SMP subsets.

e78205df5b Fixed possible deadlock from recursive INTs on same cpu. Since 
we use lazy masking INTREN()/INTRDIS() might be called with INTs enabled.
This means another higher prio INT to the same cpu could attempt to
re-enter the critical region, but would spin waiting for the lock.  Since
it is the owner, it would deadlock.

812e4da7a8 New simple_lock code in asm: 
- s_lock_init()
 - s_lock()
 - s_lock_try()
 - s_unlock()

Created lock for IO APIC and apic_imen  (SMP version of imen)
 - imen_lock

Code to use imen_lock for access from apic_ipl.s and apic_vector.s.
Moved this code *outside* of mp_lock.

It seems to work!!!

c1f94e717b Well, consensus seems very split on this so I talked it over with DG 
and he says he's happy to see forward movement in aligning our defaults
with a 16 bit world, the 8 bit folk already being veterans by this
point who know how to use userconfig.

In any case, perhaps Warner will soon come to save us all with his Dynamic
Probing(tm) feature and this will all become totally moot in any case,
so it's probably not worth arguing about either way.

8b0597671f Quick and dirty (?) fix for noatime option. The WebNFS changes 
broke it by using the same value for MNT_EXPUBLIC as for MNT_NOATIME.
Just use a different value for MNT_EXPUBLIC.
