- 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
clean up some debug code. clean up the DPRINTF() code, and expand
the interrupt mapping debug code to match schizo and psycho.
set IOMMU_TSBSIZE_IN_PTSB, and if oberon, IOMMU_FLUSH_CACHE.
disable the STC explicitly.
and specify that usb_dma attribute to dev/usb/usb_mem.c.
usb_mem.c uses bus_dma(9) for DMA memory allocation,
but non-DMA capable USB host controllers like slhci(4)
doesn't need them at all, and some ports don't bother to
prepare MD bus_dma(9) implementation (yet).
Discussed on current-users
http://mail-index.NetBSD.org/current-users/2011/03/13/msg015995.html
and usb_dma attribute is suggested by bouyer@.
Tested by kiyohara@ on mmeye with slhci at pcmcia.
usb_mem.c provides functions for DMA memory allocation
that is required by DMA capable host controllers only,
but MALLOC_DEFINE() isn't DMA specific and could be required
by any USB drivers.

to do so, move the call to fix the label inside of rf_reasonable_label()
itself, so we can fix the partition sizes before calling
rf_component_label_partitionsize() itself.
fixes the failure mode where i had garbage not in numBlocksHi but in
partitionSizeHi, and the check against rf_component_label_partitionsize()
would fail and my raid would not auto-configure.
name, provides a proper CPP mode and fixes a number of compat issues
in the integrated assembler.
Build the toolchain compiler optimized and without assertions now.
