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

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

Module Name:    src
Committed By:   mrg
Date:           Mon May 18 01:36:11 UTC 2009

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

Log Message:
- retire union cpu_info_pg
- allocate space for each cpu_info{} in pmap_bootstrap
- remap cpu0's space into the PA currently in CPUINFO_VA
- cpus[] becomes an array of pointers to cpu_info{}, easy to traverse
- only call kernel lock for IPL_VM interrupts (?  as implemented on
  x86 and sparc64)
- revert a minor part of locore.s:1.241
- in cpu_hatch(), set %sp to near the middle of the interrupt stack.
  we only need a %sp until we get to run an MI thread (own idlelwp or
  real code)

we still waste one page of space, but this gets SMP much closer to
actually working again.
