e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight 
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page.  This could cause machine checks since the PTE after the last page
would not have the valid bit set.

(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)

35e9372060 Add entries to the intvid_info table that are equivalent to 
the (in)famous MADHATTER patch.  The only one that has been
tested is the Q700, however, so the rest are conditionalized
on the MADHATTER option until they can be verified.

this is not enabled by default.  `options MACHINE_NEW_NONCONTIG'

5d5c1cd59e - avoid system stack underflow when calling sigreturn via trap #0

its implications.

fe87ac4104 fix for changes in bioscall structure and include files 1998-01-06 00:35:42 +00:00
thorpej
a8f80ad4fd Fix a bogosity apparently inherited from when the Utah 4.3BSD code base 
was converted to use Mach VM for Net2/4.4BSD.  The user segment table
pointer was originally stored in the PCB.  When Mach VM came along,
however, it was also stored in the pmap, and loaded into the PCB in
pmap_activate().  pmap_activate() would then note that the PCB's USTP
was now in sync with the pmap's USTP, and the low-level context switch
code would use the value from the PCB.

However, pmap_activate() would also load the hardware MMU context if
the pmap was the current pmap (or, in the case where pmaps can be shared,
such as in NetBSD, if the proc was the current proc).  The low-level
context switch code would then reload the hardware _again_ using the
USTP from the PCB.

However, the optimization of not calling pmap_activate() if "stchanged"
was false ended up causing some processes to use stale USTP values from
the PCB when the low-level context switch code reloaded the hardware!
This was noticed by using a real vfork(2) (which worked for some time
before failing, surprisingly!)

Since I'm hard pressed to find any real optimization here (since the
hardware was always reloaded once, sometimes twice!), the code now always
calls pmap_activate(), which uses the correct USTP value (the one in the
pmap).  The PCB's USTP is now ignored, and should eventually be g/c'd.

Another optimization can actually be performed, and I have added a comment
describing what it is, but have not yet implemented it.

Also note that most of the loadustp() functions where actually incomplete.
This has been corrected.  These functions should probably be split up into
MMU-specific operations, and called indirectly, rather than doing constant
run-time decision making based on values that will never change during the
course of a boot's lifetime.

f267fe868d - Adjust so that access to the PCB is not required in most pmap functions. 
Store the page {0,1} base and length registers in the pmap structure,
  and implement pmap_activate(), which stores them in the PCB (for the
  hardware's use).
- Re-implement pmap_pinit(); allocate the PTEs here, not in cpu_fork().

  by way of pmap_activate().
