Log Message:
Apply patch, requested my mrg in ticket 1553:
        sys/arch/sparc/sparc/cpu.c:     patch
        sys/arch/sparc/sparc/cpuvar.h:  patch
        sys/arch/sparc/sparc/pmap.c:    patch
        sys/arch/sparc/sparc/timer_sun4m.c:     patch
- print the curpcb in ddb "mach cpu" output as well.
- bump the size of cpus[] by one, so we have a NULL pointer at the end,
  from tsutsui
- for MP kernels, copy the loop to find the bootcpu in mainbus_attach()
  into getcacheinfo_obp() so we can get cache properties on the bootcpu
  before calling main()
- in getcpuinfo(), move the call of getmid() before the call to
  getcacheinfo() so that the above change to getcacheinfo_obp() can work
- move the struct cpu_info setup to the end of the initial kernel page
  setup and don't access this space until after we have switched to the
  kernel pagetables
- revive most of the old CPUINFO_VA alignment/congruency code from the
  old alloc_cpuinfo_global_va() function, and ensure that all cpuinfo
  structures are sanely aligned.  this makes hypersparc work again
- introduce a new way to free the wasted pages back to UVM, as we can't
  simply uvm_unmap() them this early in bootstrap
- make sure to initialise the cpuinfo sz in all cases.  noted by martin.
- add per-cpu event counters for lev10 and lev14 interrupts.
- make CPU_INFO_FOREACH() set the iterator count to '0' in the !MP case.
- add some disabled MP code to poke other cpus on level 14 interrupts.
- add a diagnostic to ensure that cpus[0] == cpu0's cpu_info->ci_self
- if a cpu doesn't have any mappings allocated, don't copy them.  this
  occurs if a cpu isn't attached (such as a MP kernel with only "cpu0"
  listed in the config file..)
- fix the previous to compile !MULTIPROCESSOR.
