Fix PowerPC high BATs access: BAT number was incorrect.

faadf50e 11/03/2007 03:37 pm j_mayer PowerPC MMU and exception fixes:
  • PowerPC 601 (and probably POWER/POWER2) uses a different BAT format than
    later PowerPC implementation.
  • Bugfix in BATs check: must not stop after 4 BATs when more are provided.
  • Enable POWER 'rac' instruction.
  • Fix exception prefix for all supported PowerPC implementations....

Fix PowerPC 32 emulation on 64 bits hosts:
we can use 64 bits registers but not pretend page is 1kB long
As it seems most Linux programs assume page-size is 4kB, never allow
1kB pages for user-mode only emulation.
