Rework the way kernel include files are installed. In the new method,

as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically,

the scatter/gather TLB cannot be invalidated on these chips. So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.

Several changes to the TurboChannel Dual SCSI driver:
...
- Fix the autoconfiguration model; the TCDS children don't attach to
TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"

UVM pmap's locking protocol, written by Chuck Cranor. Not all of the

Simple screen attribute handling for wscons.

The graphics device driver passes a "default attribute" for normal text

Rework PCI interrupt mapping on the EB164 systype. Rather than computing

the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions

Add a PMAP_KERNEL_PTE() macro that returns the PTE for a given KVA. If

DEBUG, this performs a table walk. Othwise, the Virtual Page Table is

Add some robustness to pmap_alloc_physpage(): Instead of panic'ing if

b86884a71a
Give pmap_collect() some substance: when called, a process is being
...
swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.
Since the pmap module is allowed to "forget" mappings, pmap_collect()
may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.

Initial mostly-working ioasic attachment for the MI 8530 SCC driver. It is

enough to use as a console on my DEC 3000/400 (connected to a VT-520

XXX The MI SCC driver needs serious changes to handle platforms which
have muliple SCC attachments (e.g. the Alpha port, which has an ioasic
attachment for TurboChannel systems and a gbus attachment for TurboLaser
systems).
XXX The MI SCC driver also needs changes to deal with the wacky (to put
it mildly) way the chips are wired up on the ioasic (on both TC Alphas
and DECstations). These are going to come along later.

- The pmap now includes support for ASNs. We no longer need to flush
...
the TLB and I-cache in the SWITCH_CONTEXT macro.
- Right after switching to proc0's newly-created context at startup time,
flush the TLB and I-cache; this is the only place where it's not done
automatically.
- Fix a nasty bug in a critical section of cpu_switch(); change the
pmap_activate -> SWITCH_CONTEXT -> pmap_deactivate sequence to
pmap_deactivate -> pmap_activate -> SWITCH_CONTEXT. This prevents
erroneously marking a pmap inactive if switching to a process that
shares it's address space (and thus its pmap) with the oldproc! Noticed
by Chris Demetriou.
