76371b8a9d include <m68k/db_machdep.h> to get the prototype for kdb_trap if DDB and 
DEBUG are defined and add a cast for the second argument to the
kdb_trap call.

b88b183ab5 Don't have kernel vs. non-kernel versions of _ENTRY(); there's no 
reason to omit the .type directive in the kernel case.

f3efbb406a The recent buserr handler cleanup in the Amiga locore.s made the label 
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

6d6e724440 Reorganize buserr/addrerr stuff, to allow omitting unused code in single-cpu 
kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.

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.

658ce85446 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.

07b064e02e New ARP system, supports IPv4 over any hardware link. 
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.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
