1fbd0b3749 GC the unused `physadr' type, which was not able to hold a complete physical 
address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

f766e521be In kcopy(), make sure we save and restore the old fault handler; kcopy()

its implications.

4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: 
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

9d04fc8ed1 New zeropage() implementation based on code contributed by Hiroshi Horitomo 
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641.   I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes.  This
reduces the size and complexity of the function.

On the '020, the simpler code is less than 1% slower.  Surprisingly, it
is ~3% faster on the '040.

e9eba07a8f Add the Utah mappedcopyin/mappedcopyout functions to a common m68k

boundaries.

- zeropage() -- a single page-aligned NBPG-byte zero.

causes a measureable performance improvement in pmap_copy_page()
and pmap_copy_page().

A few m68k ports already had copypage() in their locore.s.  It has
been moved here so it can be shared.

- correct printing of FP data register lists in the case the list is reversed
  (would have printed nothing)
- correct mapping of fp0-fp7 to register list bits (was reversed)

d137b0e8ba Added new macro _PROF_PROLOG which contains the code sequence needed 
to call mcount().  This is needed because the ``link a6,#0'' insn used
trips up gcc's ANSI preprocessor (A # in a function-type macro must be
followed by a macro argument).  _PROF_PROLOG is also used in the i386
asm.h.

Solaris' asm_linkage.h has a MCOUNT macro similar to _PROF_PROLOG
except it expands to different code sequences based on whether a
function is being compiled with "prof" or "gprof" instrumentation.

I also discovered that the m68k ALTENTRY is very different than the
implementation used by other NetBSD ports.  Usually ALTENTRY simply
provides an alternate function entry point.  The m68k version takes a
second argument and jumps inside the second function when profiling is
enabled.  The m68k behavior is similar to the ENTRY2 macro found in
solaris.

Providing ENTRY2 and changing all the code that uses ALTENTRY to use
it would be a desirable change.
