- /dev/kmem: disallow access to devices
This is designed to protect device registers from being corrupted
accidentally by "innocent" mem/kmem grovellers.
- Supply an `fputype' global. Since all hp300's have an FPU, default
it to FPU_68881, setting it to FPU_68040 if we detect a 68040 CPU.
- Use `fputype' at run-time rathern than FPCOPROC at compile-time.
- Re-arrange locore slightly; move startup code to the beginning, right
after the vector table.
allocate and initialize all kernel page tables before looking at the
PROM maps, which allows mmu_reservemon4m() to simply walk the PROM tables
without having to allocate bits and pieces of our own kernel tables.
Slightly optimize getcontext() macros in mutli-arch kernels.
Remove un-needed `4m' version of mmu_pagein().
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.

To make this work nice, big changes to the boot unit handling
was also required. From now only DEC HW unit numbering are used
in boot, to easy match boot device in kernel.
