35110949ce Ditch the `simulated' software interrupt in favour of 
hardware-assisted soft interrupts on all boards.
(Note: VMEChip2-less 162/172 not yet tested)

This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.

As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).

c22fb1db55 Finally nobble the bus_dmamap_sync() problem with osiop(4). 
Basically, bus_dmamap_sync() `PREREAD' needs to flush the cache
for the start and end of the region if it is not aligned to
a cacheline boundary, otherwise a subsequent POSTREAD can *purge*
valid data which was in the cacheline but *outside* the region
passed to bus_dmamap_sync().

Bus snooping doesn't always help here because osiop(4) calls
bus_dmamap_sync() with POSTREAD even if no data was actually
transferred! (And we can't rely on snooping on the 68060 models anyway).

2b27ac7a99 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.

937a7a3ed9 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.

fe3273fbb4 Patch from PR kern/8001, submitted by Rafal Boni. 
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards.  This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.

This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver.  I've tested it (briefly) with 'ei' on arm26
as well.  In theory, drivers other than 'ix' should follow precisely the
same code paths as before.

o Avoid checking cputype when the kernel is built for one cpu variant only.
 o In writeback(), don't use bcopy() to write a mere 16 bytes of 16-byte
   aligned data; it's much quicker to copy it inline.
