956ec2a47c The previous optimization of the interrupt handlers was a bit too 
agressive.  Being a little more conservative pays the biggest dividend.

18b2bdb000 Fix calculation of max virtual memory to be gobbled up by the buffer cache. 
Apply "stop-gap" nbuf clamp only on sun4/4c and if nbuf not explicitly
configured in.

c0b46da054 Use IOMMU_PAGE_SIZE instead of NBPG, since theoretically the IOMMU page size 
is different than the CPU page size.

f749003301 Fix part of last change: don't mask off the high bit of the VIA IER until 
the interrupt has been unflagged.  Problem noticed by Paul Goyette.

93d8b2c8b0 Add the MAC68K_BROKEN_VIDEO option, which is a hack that delays enabling 
NuBus interrupts until an Ethernet card is attached.

63183795c0 imask[IPL_ZERO] was updated after recomputing the run masks for all the 
interrupt handlers. Due to this
  - DIAGNOSTIC kernels would panic
  - check_sir would run with the interrupt registered last blocked
Credits for finding and fixing this go to Ian Dall.

705c637874 Define aesetup() to return an int, so that the attach function can 
determine whether there was an error (if so, we unmap the slot space
for this device).  Use this functionality to tell the attach function
that we couldn't clear the card's buffer.

Also in aesetup(), eliminate the bogus repetition of the error message
we print when the buffer clear actually fails.  Noticed by Hauke Fath.

17fdd597df Move the NuBus-specific watchdog function from if_ae.c to if_ae_nubus.c,

do some minor cosmetic surgery (rename bus space tags/handles and some
KNFing I missed the first time around).

compiled-in defaults.
