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

Module Name:    src
Committed By:   mrg
Date:           Sun Mar 20 21:26:36 UTC 2011

Modified Files:
        src/sys/arch/sparc64/dev: iommu.c

Log Message:
re-add most of the pryo-supporting code, and some general clean up:
- handle setting tsb size in the ptsb via IOMMU_TSBSIZE_IN_PTSB (partly from
  openbsd)
- fix IDB_INFO for systems without a STC that fault on accesses to the
  flush register (like pyro)
- move iommu_reset() to the end of iommu_init()
- use IOMMUREG_WRITE() in a few places
- add a missing membar_lookaside() (from openbsd)
- if pmap_extract() on the flush buffer fails, disable flushing (from openbsd)
- flush the pyro-style iommu when IOMMU_FLUSH_CACHE is set (partly from openbsd)
- clear up a bit of debugging code so it spew a little less (sometimes you will
  get kernel lock spinouts due to long scrolling printfs)
- use __func__ in several places
