7dbfdb5508 In the 32-bit ABI case: 
* rename sigcontext.sc_tstate to sc_psr, since this is how it is known to
  the 32-bit API, and also used for;
* don't try to squeeze the tstate into it, just emulate the ICC bits.

Per discussion with Eduardo.

7ec840fbe5 Add comment to tell what cpu_fork() does around at its bottom. 
What's wrong; the initial SR value in pcb0 gets overwritten before
the first kthread_create1() is called.  For a normal process which
has user mode it doesn't matter because proc_trampoline() makes
the process to have spl0 during exception return path to user mode,
however, kthreads stay in kernel mode mistakenly left in splhigh
condition.  The trouble is visible as severe clock drifts when
system activity is high.

580e36f497 Make sure to have spl0 condition whenever a new thread of control 
is created.  System kthreads are mistakenly left splhigh state.

pcb0 has an initial SR value for spl0 condition which are expected to
be propagated to all of children

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.

d7e12660a3 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.
