This adds SMP support to UML. All global data owned by UML is now either
locked or is commented as to why no locking is needed. All interrupts
are currently handled by CPU 0. The special handling of the timer interrupt
is now gone.

Fixed the non-SMP build.
ChangeSet@1.784, 2002-10-14 11:31:46-04:00, jdike@uml.karaya.com
config.in now defines CONFIG_NR_CPUS.
ChangeSet@1.783, 2002-10-14 09:53:55-04:00, jdike@uml.karaya.com
This is the merge of the initial 2.4 SMP support.
Locking was added where necessary.
All processors take timer interrupts, but only CPU 0 calls the timer
IRQ. The others just call update_process_times to keep the
accounting straight.
The timer interrupt is blocked along with the other signals.
