NetBSD/x86: Raise the number of interrupt sources per CPU from 32 to 56.

There has been no objection for three years.

Some devices (e.g. ixg in MSI-X mode) don't to have their handlers called
when no interrupt are pending. So add an extra ih_pending field
to struct intrhand, which is incremeted when the handler is not called because
of IPL level and reset to 0 when called. Check this in Xen's resume
assembly to call only handlers that are really pending.

Reorganise sources to make it possible to include Xen PVHVM support in
native kernels. Among others:
- move xen/include/amd64/hypercall.h to amd64/include/xen and
  xen/include/i386/hypercall.h to i386/include/xen
- exclude some native files from the build for xenpv
- add xen to "machine" config statement for amd64 and i386
- split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers)
  and arch/xen/conf/files.xen.pv (for full pv support)
- add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV

Welcome XENPVHVM mode.

It is UP only, has xbd(4) and xennet(4) as PV drivers.

The console is com0 at isa and the native portion is very
rudimentary AT architecture, so is probably suboptimal to
run without PV support.

Allow x86 builds to have the opportunity to not have pre-emption
enabled by default. This can be effected by having a:

"options	NO_PREEMPTION"

line in the kernel configuration file.

While it was tempting to tie __HAVE_PREEMPTION to MULTIPROCESSOR,
as is currently assumed in sys/kern/kern_stub.c ,

having MULTIPROCESSOR without __HAVE_PREEMPTION
and not having either are valid configuration options which users
could have choice of. We thus err on the side of configurability.

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.

if checking whether an interrupt is shared, don't compare pin numbers
if it is "-1" -- this is a hack to allow MSIs which don't have a concept
of pin numbers, and are generally not shared
(This doesn't give us sensible event names for statistics display. The
whole abstraction has more exceptions than regular cases, it should
be redesigned imho.)

cpuctl:

- Add interrupt shielding (direct hardware interrupts away from the
  specified CPUs). Not documented just yet but will be soon.

- Redo /dev/cpu time_t compat so no kernel changes are needed.

x86:

- Make intr_establish, intr_disestablish safe to use when !cold.

- Distribute hardware interrupts among the CPUs, instead of directing
  everything to the boot CPU.

- Add MD code for interrupt sheilding. This works in most cases but there is
  a bug where delivery is not accepted by an LAPIC after redistribution. It
  also needs re-balancing to make things fair after interrupts are turned
  back on for a CPU.

Add support for kernel preeemption to the i386 and amd64 ports. Notes:

- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.

The only functional change is the removal of the unused evcnt.h include in

other in the rest of the tree but I'm only compiling i386's QEMU for the

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

- Implement soft interrupts as kernel threads. A generic implementation
  is provided, with hooks for fast-path MD code that can run the interrupt
  threads over the top of other threads executing in the kernel.
- Split vnode::v_flag into three fields, depending on how the flag is
  locked (by the interlock, by the vnode lock, by the file system).
- Miscellaneous locking fixes and improvements.

Add hooks and structures to allow the MP table intr mapping code a
better shot at finding a mapping. For PCI interrupts, if a bus
has no mappings, try its parent, with the swizzled pin, and the
bridge's device number.

Move the bulk of pci_intr_string into a seperate intr_string function. Use
that new function to print the pciide compat interrupt in pciide_machdep.c.
Share pciide_machdep.c between amd64 and i386.

Pass pointers to frames from assembly, do not use the 'frame on stack
as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions
about the stack that will not be true. Costs 2 instructions per trap/syscall
on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64,
2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better
optimization (it'd better..)

While here, make amd64 compile again by using subr_mbr_disk.c

Block level-triggered interrupts at the ioapic if they are deferred.
Avoids interrupt storms seen on some systems. Many thanks to
Stoned Elipot for testing.

other ports.
