d3c3fef89b add code from tsubai to handle the second CPU on openpic machines. 
the second CPU on dual G4 boxes works now.
while I'm here, use mfmsr() and mtmsr() instead of inline asms.

f7fb853264 be sure to re-enable interrupts before calling trap() a second time 
due to an AST.  the rule is that we must always have interrupts
enabled when acquiring kernel_lock, so that we can process blocking IPIs
from another CPU which is already holding kernel_lock.
reduce differences between the MP and non-MP versions of this file.

f73abf90fb on MP systems, if the firmware didn't configure the L2 cache 
on the non-boot CPUs, copy the L2CR configuration from the boot CPU.
also, fix the code that configures the L2 cache so that it works at all.
while I'm here, use mfspr() and mtspr() instead of inline asms.

301f1ebf31 move more inlines to cpu.h: mftb(), mftbl() and mfpvr(). 
(the mftb() in pmap.c only wanted the lower 32 bits, so that's now mftbl()).

ed8346a525 Rather than forcing on XS_POLL in SCSI transfers ourselves, set 
SCSIPI_ADAPT_POLL_ONLY to tell the MI scsipi layer to do it for us.  This,
plus G/Cing some debugging code, removes the card-specific scsi_request
wrappers.

16cf89e5a5 Made changes in where/how the kernel is linked, and how the pmap 
maps it with BTLB entries, to minimize the number of BTLB entries
needed.

Because the CPU type was often guessed incorrectly, the mapping of
HP board number to system name now includes information about the
expected CPU type.

3295720e1a Don't use ldcw, since netisr might not be 16-byte aligned. 
Instead, disable interrupts and do a load and a store.

1aaddc3669 - Care about carry bit when adding short value to force 4 byte boundary. 
It may contain any 32 bit value there.
- Use correct instruction to clear carry bit.
- Don't use series of load with update instruction.  It's slower.

5b89d2589b In DIAGNOSTIC kernels detect situation that on sun4m neither hardware 
nor software interrupt pending bit is set for the current ipl.  Report
this as a "bogus" interrupt (better name anyone?).  This is a symptom
of a bug in interrupt handling in one of device drivers interrupting
at this ipl.  Reviewed by pk.
