64dac503e8 System-specific handling of bus errors for DECstation variations 
supporting parity errors only for memory (Pmax/3min/Maxine).
Fixes for resources decoded by the KN04/KN05 MB ASIC.  Additional
clean-ups for the ECC handler.

baee502ce2 Get rid of the eir struct mips_fpu_emulator_private member. It's 
never initialized been initialized anywhere, just saved to and
restored from signal frames so nonsense anyway.  As neat side effect
of being shared between all processors it was also abusable as a
nice covert channel between processes.
