15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

24e7ecca97 Adjust the way the cpu_info[] array works (array of pointers 
rather than array of structures).  Keep a list of active
CPUs and define a CPU_INFO_FOREACH to traverse them.

This fixes cpustates statistics tracking.

9f142f57b9 In the provisional disklabel (which will be used if there is no 
valid on-device disk label), set d_npartitions to RAW_PART+1 instead
of to 1.  Discovered as a build bug on the netbsd-1-5 branch, affecting
miniroot construction and vnd devices; RAW_PART went missing from the
in-core disklabel, and eventually also the on-device label.

e84fefd1f1 pmap_asn_alloc(): In a multiprocessor configuration, it's possible 
to arrive here referencing the kernel_lev1map without having the
RESERVED ASN -- another CPU may have caused pmap_lev1map_destroy()
to be called, and that routine only invalidates the ASN for the
CPU that called it.  So, in the MULTIPROCESSOR case, simply assign
the RESERVED ASN if we reference the kernel_lev1map rather than
asserting that we already have the RESERVED ASN.  Thanks to Bill
Sommerfeld for helping me track down the problem.

Also add a new IPI that causes a CPU to re-activate its address
space if the pmap it's using changes level 1 maps (this probably
won't happen very often, but it's correct to have it).

This makes Alpha MP kernels boot multiuser.  In fact, this commit
is being made from my dual-CPU AlphaServer 1200 running an MP kernel.

1bf3f87777 Fix a problem with kcopy()/copyin()/copyout() on MP systems 
that became apparent when UBC was added: store a pointer to
the process itself, not a pointer to ci->ci_curproc.

This gets us back to where we were before UBC went in: MP
kernels get to single-user mode, and can run processes on
both CPUs, but things go south when we try to come into
multi-user mode.

a51a1d8cdd - Get rid of the prot bits in the mem_clusters[] array when 
reserving RAM in the bus_mem extent map.  Problem pointed
  out by Artur Grabowski.
- Work around a slightly annoying bit of behavior exhibited by
  the UP1000 firmware.  The UP1000 firmware reports the space
  consumed by the "ISA hole" in the same MDDT entry as two
  chunks of RAM (on either side of the hole) used by the PALcode,
  all as one "reserved for PALcode" chunk.  We must take this
  into account when reserving RAM in the bus_mem extent map.
