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.

Add several useful macros:
...
- ENTRY_NOPROFILE() and ASENTRY_NOPROFILE(), similar to ENTRY() and
ASENTRY(), but without the profiling prologue.
- GLOBAL()/ASGLOBAL() and LOCAL()/ASLOCAL(), for defining global and
local variables with C and ASM labels.
- BSS()/ASBSS(), for defining items in the BSS segment, with C or
ASM labels.
- PANIC("panic message") - shorthand for calling panic() from assembly code.
- VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries
in the vector table.
Also, change RCSID() to pad out the string to even boundary.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

the is-newarp branch.

Add the Utah mappedcopyin/mappedcopyout functions to a common m68k
...
area. These functions are designed to improve performance of large
copyin/copyout operations by mapping the user page in to the kernel
address space and using bcopy(), rather then copying across protection
boundaries.
XXX This doesn't work yet -- the way it's called doesn't obey C calling
XXX conventions. That will be fixed soon.

Add two optimized functions used by pmap.c:
...
- copypage() -- a single page-aligned NBPG-byte copy.
- zeropage() -- a single page-aligned NBPG-byte zero.
These functions don't play around with alignment, etc. Their use
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.
