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.

e27fb7b666 param.h:
Macros to convert the Lite2 lock manager primitives to the names used
	in the kernel proper.  This allows us to hide them from the lock
	manager till they can be turned on.
smp.h:
	declarations for the new simplelock functions.

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!!!

Evidently this has never been compiled before, NOT a good sign...

1dec61e7c0 Added code to support #define APIC_PIN0_TIMER.
This code ALWAYS runs the 8254 timer thru the 8259 ICU.
It depricates the usage of "options SMP_TIMER_NC" in the config file.

78342719d6 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...

0a0a85b3e0 Add support for 4MB pages. This includes the .text, .data, .data parts
of the kernel, and also most of the dynamic parts of the kernel.  Additionally,
4MB pages will be allocated for display buffers as appropriate (only.)

The 4MB support for SMP isn't complete, but doesn't interfere with operation
either.

General cleanup.

New functions to stop/start CPUs via IPIs:

 - int stop_cpus( u_int map );
 - int restart_cpus( u_int map );

Turned off by default, enabled via smptests.h:TEST_CPUSTOP.
Current version has a BUG, perhaps a deadlock?

via an IPI.

7bcc0f3d66 Allow the kernel configuration file to override the amount of memory
available to the kernel (VM_KMEM_SIZE). The default (32 MB) is too low
when having 512 MB or more physical memory in a server environment. This is
relevant on systems where "panic: kmem_malloc: kmem_map too small" is a
problem.
