fd81cf2b92 Correct offsets in the memory size probe; bus_space uses byte offsets. Fix suggested by 
Ken Nakata.

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

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.

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.

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

b89a3425b7 Eliminate obsolete TIMEZONE and DST options. 
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

series with hard hangs in this function.

8bd4e6d18e Sync with current 040-related development: 
- Figure out what CPU we have, rather than assuming the Booter knows,
   and set cputype variable accordingly.
 - Carefully rearrange the order of various MMU/ATC operations so as to
   eliminate possible side effects.  Also, re-order the initial bootstrap
   code to make clear what various sections of this code do.
 - Adjust to combined initenv()/genenvvars() (the latter has assimilated
   the former).
 - Add a function code argument to ptest040().
 - Use symbolic constants from assym.h where appropriate (and defined).
 - Some style cleanup.

   some machines; use an ADD instead of an OR when determining the PA.
