Change event_set_handler() to take the target CPU parameter. If ci is NULL,
  event_set_handler() will choose the CPU and bind the event.
  If ci is not NULL the caller is responsible for binding the event.
Use a IPI xcall to register the handlers if needed.
pull in a hack from x86 to force pirq handlers to be mpsafe if registered at
a level != IPL_VM. This is for the com at isa interrupt handler, which
registers at IPL_HIGH and has to way to tell it's mpsafe (taking
KERNEL_LOCK at IPL_HIGH causes deadlocks on MP systems).

add support for using MSI for XenPV Dom0

use PHYSDEVOP_map_pirq to get the pirq/gsi for MSI/MSI-X, switch also INTx
to use it instead of PHYSDEVOP_alloc_irq_vector

MSI confirmed working with single-vector MSI for wm(4), ahcisata(4), bge(4)

XXX added some provision for MSI-X, but it doesn't actually work (no interrupts
delivered), needs some further investigation; disable MSI-X for XENPV
via flag in x86/pci/pci_machdep.c

By default, events are bound to CPU 0 (exept for IPIs and VTIMERs which
are bound to a different CPU at creation time).
Recent MI changes caused the scheduler to choose a different CPU when
probing and attaching xennet devices (I guess it's the xenbus thread which
runs on a different CPU). This cause the callback to be called on a different
CPU than the one expected by the kernel, and the event is ignored.
It is handled when the clock causes the callback to be called on the right
CPU, which is why xennet still run, but slowly.

Change event_set_handler() to do a EVTCHNOP_bind_vcpu if requested to,
and make sure we don't do it for IPIs and VIRQs (for theses, the op fails).

add support for kern.intr.list aka intrctl(8) 'list' for xen

event_set_handler() and pirq_establish() now have extra intrname
parameter; shared intr_create_intrid() is used to provide the value

xen drivers were changed to pass the specific driver instance
name as the xname, e.g.  'vcpu0 clock' instead just 'clock', or
'xencons0' instead of 'xencons'

associated evcnt is now changed to use intrname - this matches native x86

Retire xen/x86/intr.c and use the new xen specific glue in x86/x86/intr.c

The purpose of this change is to expose the x86/include/intr.h API
to drivers. Specifically the following functions:

   void *intr_establish_xname(...);
   void *intr_establish(...);
   void intr_disestablish(...);

while maintaining the old API from xen/include/evtchn.h, specifically
the following functions:

    int event_set_handler(...);
    int event_remove_handler(...);

This is so that if things break, we can keep using the old API until
everything stabilises. This is a stepping stone towards getting the
actual XEN event callback path rework code in place - which can be
done opaquely behind the intr.h API - NetBSD/XEN specific drivers that
have been ported to the intr.h API should then work without
significant further modifications.

Simplify the xen event handler callback by:
 - moving the interrupt handler callback traversal into a separate
   function.
 - using evt_iterate_bits() to scan through the pending bitfield
 - removing cross-cpu pending actions - events recieved on the wrong
   vcpu are re-routed via hypervisor_send_event().
 - simplifying nested while() loops by encapsulating them in
   equivalent functions.

Many thanks for multiple reviews by bouyer@ and jym@

Merge jym-xensuspend branch in -current. ok bouyer@.

Goal: save/restore support in NetBSD domUs, for i386, i386 PAE and amd64.

Executive summary:
- split all Xen drivers (xenbus(4), grant tables, xbd(4), xennet(4))
in two parts: suspend and resume, and hook them to pmf(9).
- modify pmap so that Xen hypervisor does not cry out loud in case
it finds "unexpected" recursive memory mappings
- provide a sysctl(7), machdep.xen.suspend, to command suspend from
userland via powerd(8). Note: a suspend can only be handled correctly
when dom0 requested it, so provide a mechanism that will prevent
kernel to blindly validate user's commands

The code is still in experimental state, use at your own risk: restore
can corrupt backend communications rings; this can completely thrash
dom0 as it will loop at a high interrupt level trying to honor
all domU requests.

XXX PAE suspend does not work in amd64 currently, due to (yet again!)
page validation issues with hypervisor. Will fix.

XXX secondary CPUs are not suspended, I will write the handlers
in sync with cherry's Xen MP work.

Tested under i386 and amd64, bear in mind ring corruption though.

No build break expected, GENERICs and XEN* kernels should be fine.
./build.sh distribution still running. In any case: sorry if it does
break for you, contact me directly for reports.

- Upgrade suspend/resume code to comply with Xen2 removal.
- Add support for PAE domUs suspend/resume.
- Fix an issue regarding initialization of the xbd ring I/O that could end
badly during resume, with invalid block operations submitted to dom0 backend.

NetBSD supports PAE under x86_32 by considering the L2 page as being
4 pages long instead of 1.

Xen validates the page types during resume. Sadly, the hypervisor handles
alternative recursive mappings (== PG/PD entries pointing to pages other
than self) inadequately, which could lead to incorrect page pinning.

As a result, the important change with this patch is to clear these alternative
mappings during suspend, and reset them back to their former self upon
resume. For PAE, approx. all 4 PDIR_SLOT_PTEs could be considered as
alternative recursive mappings.

See comments in pmap.c for further details.

Now, let the testing and bug hunting begin.

Initial code for xen save/restore/migrate facilities.

- split the attach code of frontends in two half: one that is only needed
during autoconf(9) attach/detach phases, and one used at each save/restore
of device state (between suspend and resume).

Applies to hypervisor, xencons, xenbus, xbd, and xennet.

- add a rwlock(9) ("ptom_lock") to protect the different parts in the kernel
 that manipulate MFNs (which could change between a suspend and a resume,
without the kernel noticing it). Parts that require MFNs acquire a reader lock,
while suspend code will acquire a writer lock to ensure that no-other parts
in kernel still use MFNs.

- integrate the suspend code with sysmon.

- various things in pmap(9), and clock.

TODO:
- factorize code a bit more inside frontends drivers.
- remove all alternative recursive (APDP_PDE) mappings found in PD/PT during
suspend, as Xen does not support them.
- abstract the ptom_lock locking, it is only required when kernel preemption
is enabled, or on MP systems.

Current code works mostly. You may experience difficulties in some corner
cases (dom0 warnings about xennet interface errors, and Xen tools failing to
 validate NetBSD's alternative pmaps).

- rename init_events() to events_init(), to better reflect netbsd semantics

- change unbind_[pv]irq_from_evtch() so that they now return the event
channel the [PV]IRQ was bound to. It reflects the opposite behaviour of the
bind_[pv]irq_to_evtch() functions.

- remove xenbus_suspend() and xenbus_resume() prototypes, as they are not
used anywhere else, and will conflict with the xenbus pmf(9) handlers.

- make start_info aligned on a page boundary, as Xen expects it to be so.

- mask event channel during xbd detach before removing its handler (can
avoid spurious events).

- add the "protocol" entry in xenstore during xbd initialization. Normally
created during domU's boot by xentools, it is under domU's responsibility
in all other cases (save/restore, hot plugging, etc.).

- modifications to xs_init(), so that it can properly return an error.

Add Xen3 support for ACPI and/or MPBIOS + IOAPIC. To help with this, physical
CPUs are now configured on mainbus only in dom0, and only to know about
their APIC id. virtual CPUs are attached to hypervisor as:
vcpu* at hypervisor?
and this is what's used as curcpu(). The kernel config files needs to be
updated for this, see XEN3_DOM0 or XEN3_DOMU for examples.
XEN3_DOM0 now has acpi, MPBIOS and ioapic by default.
Note that a Xen dom0 kernel doens't have access to the lapic.

is usually only one handler per event, unless the event is mapped to a

Deffered events and software interrupts are handled by a bitmask (as before)
with one bit per IPL. When one IPL has an event pending all handlers for
this IPL will be called.
With this change, it is now possible to have all the 1024 events active.
While here, handle debug event in a special way: the handler is always called,
regardless of the current IPL. Make the handler print usefull informations
about events and IPL states.
Also remove code not used on Xen in files inherited from the x86 port.

- Add a centralised handler for physical interrupts, which will call the
  real handler. This is not necessery but is usefull for debug.
- make irq_needs_unmask_notify[] per-IRQ, instead of per physical IRQ
- use a static physdev_op_t for PHYSDEVOP_IRQ_UNMASK_NOTIFY (it never changes,
  so no need to allocate a new one each time)
- call pirq_notify() from hypervisor_enable_irq().
