30f9be231f Restructure cpu_reboot() a bit, and add support for powering down 
on the Sun4m if RB_POWERDOWN is specified.

panics seen on a floppy boot in setroot() as it could not properly

6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

9dae8945ef In kvm_uncache(), turn off the PTE cache bit even after calling 
pv_changepte(). Reason: the managed() macro does not take into
account the gap in the managed pages range that may have been introduced
by the page table allocation in bootstrap().

e615541de9 Maintain far more complete state in the PV lists on the cacheability of pages, 
using separate flag bits for mappings that were requested to be not
cacheable and uncacheable pages due to incongruent aliases.

This avoids inadvertently turning on the cache-enable bits when removing
one of multiple virtual address mappings to the same page. Reading
from /dev/mem could do this to arbitrary pages.

b6933ca39d Reading back the IOMMU registers apparently has the ability to wedge 
microSPARC I cpus. Instead insert a couple of no-ops that seems to
avoid the microSPARC II lossage just as well.

workaround" flags.)
