as this breaks C++ code that happens to indirectly include this header.
Both Matthias Scheler and I noticed this, independently.
This problem notably does not affect the atari and sun3/sun3x ports,
which have already implemented a similar solution.
in new hp300spu.h file. This includes the code that associates
model number with cpu/mmu/cache combinations.
- Define "mmuid" constants for several models, derived from code
provided by Mike Smith.
- place all interrupt-related macros, prototypes, etc. into <machine/intr.h>,
like other ports.
- rename isrlink/isrunlink/isrinit, etc. intr_establish/intr_disestablish/
intr_init, etc., and move to intr.c for naming consistency.
- don't call intr_init() twice.
properties such as "M68040" and "M68K_MMU_MOTOROLA", used to conditionally
compile code. This is more in-line with now the other m68k ports do it,
and makes it much easier to find "common ground" among them.
In locore.s, use the MMU-type constants defined my <machine/cpu.h> rather
than "expanded" values.
Because HP300-model names are mapped to CPU/MMU combinations in
<machine/cpu.h>, no change to kernel configuration will be necessary.
