Ok, suggesting myself:

The 3 existing <machine/bat.h> files will get a definition

#define	battablesize	16
#define	battableshift	28

amigappc will use instead

#define battablesize	256	(maybe 64)
#define battableshift	24	(maybe 26)

right _before_ including <powerpc/bat.h>

[Assembler files might want to rotate left by (33-battableshift) and mask, but
those are machine dependent anyway, currently.]

Machine independent code, especially the battable declaration in
<powerpc/bat.h>, will use these declarations instead of hardwired numbers.
