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.

e14ea342e3 Some changes to make ADB work when compiled with -O2: 
- extdms_done is modified by things outside of our direct control;
    it needs to be declared `volatile'
  - CountADBs() fails when we call it the second time.  We can work
    around this by telling extdms_init() how many ADB devices we have,
    only calling CountADBs() once.

233a1d3f57 Use only FC $1 in TT0 in get_pte(), and map the entire address space. We 
can then access the page table entries directly using user data space with

series with hard hangs in this function.

Warning:  do not call any function that accesses user data space (FC $1)

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.

 - Hardwire some PowerBook internal video addresses, from Takashi Hamada.
 - When printing out the machine model/CPU, use the new cputype variable
   instead of the Booter's PROCESSOR environment variable.
 - Use new ptest040() function code argument (though for now, the MMU is
   disabled on the 040).
 - Revert previous change in get_physical() that seems to have broken
   some machines; use an ADD instead of an OR when determining the PA.
 - Some (very minor) style cleanup of asm code.

96acdadef7 First step inn removing config_scan() and the hacks that gave devices 
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

detection to the hard zs interrupt handler; the softint handler
will notice that something has happened with CTS and restart the

057adea27d Apparently the MRG ADB code becomes unstable if we handle via1 interrupts 
properly, so go back to unflagging them all before processing any via1
interrupts.  Perhaps this can be changed back when we get ADB code that
does not rely on the ROMs?

4b712a8c3f Due to the latching effect of the 6522 (VIA) chip, we need to unflag 
interrupts only after the condition that caused the interrupt has been
cleared.  This is a particular problem with the 5380 SCSI controller,
since the Mac glue logic may raise (e.g.) the SCSI DRQ interrupt a number
of times during the course of a normal transfer.  By waiting to unflag it,
we effectively ignore all but the first.

2e936aa8ff - Remove several hacks that didn't do much but waste cycles.

enough to bring the system up.
