This code was split off from apic_ipl.s.
It contains the Lite2 lock manager primitives:

 - s_lock()
 - s_lock_try()
 - s_unlock()

68126f0545 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.

31c730f3a6 New simple_lock code in asm:

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.

480e1d62b7 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.

d432b54afc Moved some definitions of initialized data nearer to the start of 
the file so that this compiles without forward declarations of that
data.  (It is impossible to forward-declare static data in Gnu C.
Declaring it as static is correct, but causes bogus warnings from
gcc -Wredundant-decls.  Declaring it as extern works, but causes
correct warnings from gcc -pedantic and is undefined in ANSI C.
We usually declare it as extern.  Here it was once really extern,
but botched staticization left it as static here and apparently-
extern in a header file.)

53c148264d Hopefully fix a few problems that could cause hangs in SMP mode. 
1)	Make sure that the region mapped by a 4MB page is
	properly aligned.
2)	Don't turn on the PG_G flag in locore for SMP.  I plan
	to do that later in startup anyway.
3)	Make sure the 2nd processor has PSE enabled, so that 4MB
	pages don't hose it.

We don't use PG_G yet on SMP -- there is work to be done to make that
work correctly.  It isn't that important anyway...
