- Map in all physical memory first in system space. This reduces
pmap_copy_page() and pmap_zero_page to 3 resp. 2 instructions.
- Have fized position user page tables. Makes the pv_table smaller
and all reverse references faster (and simpler).
- Remove the wiring code. Nobody doesn't even know what a DR32 is anymore.
- Simulate page reference bit by setting page invalid, as suggested by
Rich Draves in a paper for 1991 Mach Usenix Symposium.
This reduced the time spent in the pmap module to between 70-75% of
the previous; and made process startup _much_ faster.

Add target.c to Makefiles.
* Minor fixes:
* Fix buglet in disks.c: make sure the target /etc exists before
touching the target's /etc/fstab. (Could be even cleaner.)
* If the target root is on /, don't copy our temporary /etc/resolv.conf
to the target /etc/resolv.conf. (Could be even cleaner.)
* Don't write the DNS hostname into /etc/defaultdomain.
DNS search paths are often not the same as YP group names.
run_prog_or_die() -- aborts if system() returns an error.
run_prog_or_continue() -- prints a warning that installation may
have failed but lets the user continue. Suitable for running mkdir.
Supports changing media with ifconfig's "media" directive.
This splits the 3c503 functionality out of the ISA "ed" driver, much the
same way NE2000 support was split out.
* order SEE ALSO on man section then alphabetical
* add -w to usage string
* deprecate register
* minor code move in newman section, to follow style of oldman section
RAW_PART for new labels, instead of just the latter.
Avoids shrinking RAW_PART label with pmax kernel-supplied default
labels or with already-labelled disks.
XXX Get real incore label, instead of default label instead (or as well)?
