CVS commit: src/sys/arch/sparc/sparc

[matthew green <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg

Modified Files:
        src/sys/arch/sparc/sparc: cpu.c cpuvar.h pmap.c

Log Message:
- 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

i believe that the first used cpuinfo_data page is still being wasted,
but i haven't checked.
