78492e307a If not MULTIPROCESSOR then identify the interrupt target cpu by hwrpb id (%d) 
rather than attachment name, and hence avoid referencing `cpus'.

the secondary works, but not when called from here?!  XXX!

70d1e71ea0 Allow to use the RTC chip in a way compatible to OSF/1: use an offset 
of 52 years between RTC and UNIX time.
This is controlled by "option CLOCK_COMPAT_OSF1".

99698d1a1a - Use a bitmask for "running CPUs", rather than a flag in the softc. 
- Add a function to halt a secondary CPU.
- Enable interrupts on secondary CPUs once they've hatched.

183f609c83 - Do not set TLCPUMASK on non-I/O nodes. That register exists only on 
I/O nodes.  Previous code erroneously set it on CPU nodes only.
- In both the single- and multi-processor case, route all interrupts from
  I/O nodes to the primary CPU, for now.

2c50ec242f Add basic interprocessor interrupt sending and receiving code. Current 
IPI functions: HALT, IMB, TBIA, TBIAP.

XXX HALT is not yet implemented, it's just a stub.

d3ce2be01c Don't bother printing the message from the secondary console. All it is 
is basically the acknowledgement of the START command.  Print the idle
USPACE address for now.  Use the alias "apcb_backup_ksp" when setting the
backup kernel stack pointer in the secondary's boot HWPCB.

57e656b2ec The processor unique value in the PCB is used as a backup kernel stack 
pointer when booting secondary CPUs.  Add an alias for it.

fcb0203141 First-cut at code to spin up secondary processors on a multiprocessor 
Alpha system, conditional on MULTIPROCESSOR.

NOTE: This does not yet work completely.  The secondary CPU begins the
boot process, but never makes it into the cpu spinup trampoline.  This
is merely a snapshot of a work-in-progress.
