SGMAPs if a direct-mapped window fails.

34bbe5cd80 Rework ALCOR/ALCOR2/Pyxis recognition Yet Again. (Actually, just the 
way it's displayed, and mask off the revision once we've determined
which chip we're talking to.)

0624060713 Rework PCI interrupt mapping on the EB164 systype. Rather than computing 
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register.  The previous scheme did not work properly on
AlphaPC 164SXs.  Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

469658d533 - Allow all valid SCSI id's to work on the SII and first two ASC 
controllers (including SCSI id 7 on the 2100/3100).
- On the pmax (2100,3100) set the host SCSI id to 6.
- Move disk and tape config for the second ASC controller from the GENERIC
  config file to scsi.pmax so all configurations can use the second
  controller.

4665241bf8 Simplify the direct-mapped DMA case somewhat by adding a window base 
member to the DMA tag, and calling the direct-mapped back-ends directly,
rather than through chipset-specific front-ends which pass the window
base as an additional argument.

8c45fef21f When changing the mapping on a page, remove the previous mapping if 
there is one.  The Mach VM system seems to take care of this, so it
hasn't knowingly caused a problem.  UVM does change mappings without
removing the current mapping, and will pmap_page_protect() hangs
if pmap_enter() doesn't remove the previous mapping.

e615541de9 Maintain far more complete state in the PV lists on the cacheability of pages, 
using separate flag bits for mappings that were requested to be not
cacheable and uncacheable pages due to incongruent aliases.

This avoids inadvertently turning on the cache-enable bits when removing
one of multiple virtual address mappings to the same page. Reading
from /dev/mem could do this to arbitrary pages.

b6933ca39d Reading back the IOMMU registers apparently has the ability to wedge 
microSPARC I cpus. Instead insert a couple of no-ops that seems to
avoid the microSPARC II lossage just as well.

c099eb3a4a Add a function, pci_bus_flags(), that determines which flags (for memory 
and i/o enabled) should be passed to the primary PCI bus's autconfiguration
node.  Use this function to detect broken PCI-Host bridges, which have
problems with memory-mapped access.  Add the SIS 85C496 to this list.
