Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
...
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

Pull up the thorpej_scsipi branch to main branch.
...
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

Work around the problem that causes kern/12554. Basically,
...
there are some pathological cases that cause pmap_page_protect()
to be called on a wired page to revoke all mappings. We
need to skip mappings that are actually wired to prevent Bad
things from happening later.
THIS IS JUST A WORK-AROUND. We need to prevent the pathological
behavior from happening in UVM to begin with. But it's unclear
what the right solution is there, right now.

The Alpha pmap_virtual_space() can return compile-time constants,
...
so do so. This allows us to call uvm_pageboot_alloc() before
pmap_bootstrap().
Also, the virtual_start variable is unneeded in the Alpha pmap
module, and virtual_end (and the mostly-unused-except-by-bus_dma
variables avail_start and avail_end) can be `computed' at the
same time.

Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call. I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.

pmap_asn_alloc(): In a multiprocessor configuration, it's possible
...
to arrive here referencing the kernel_lev1map without having the
RESERVED ASN -- another CPU may have caused pmap_lev1map_destroy()
to be called, and that routine only invalidates the ASN for the
CPU that called it. So, in the MULTIPROCESSOR case, simply assign
the RESERVED ASN if we reference the kernel_lev1map rather than
asserting that we already have the RESERVED ASN. Thanks to Bill
Sommerfeld for helping me track down the problem.
Also add a new IPI that causes a CPU to re-activate its address
space if the pmap it's using changes level 1 maps (this probably
won't happen very often, but it's correct to have it).
This makes Alpha MP kernels boot multiuser. In fact, this commit
is being made from my dual-CPU AlphaServer 1200 running an MP kernel.
