Remove legacy XEN source public API from source.

Welcome to Xen 4.1.2 headers.

New interfaces for PV drivers:
- Xen transcedent memory
- USB IO
- SCSI IO

PCI IO improvements:
- PCI MSI support
- PCI Express AER support

New features:
- xen honors flags to be placed into guest kernel available pte bits
  if enabled (for grant table)
- support for 128 vcpus
  (old interface is still present and supports up to 32 vcpus)
- PCI passthrough: new hypercalls to support SR-IOV
- new hypercall for physical cpu hotplugging
- new hypercall for physical page offlining
- fixes to compile with clang
- machine check recovery mechanism

merge. The 'conflicts' happened because xen-public was once used for xen2 headers.

re-import xen3-public to rename this to xen-public

Replace x86 memory fences in Xen drivers by their Xen equivalents, to reduce
MD dependency:

x86_lfence() => xen_rmb()
x86_sfence() => xen_wmb()
x86_mfence() => xen_mb()

Access Xen's vcpu info structure per-CPU.
Tested on i386 and amd64 (both dom0 and domU) by me.
Xen2 tested (both dom0 and domU) by bouyer.

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.

Ajust for Xen 3.1.0 public headers. From Christoph Egger in private mail.

sync with head.

Apply patch (requested by bouyer in ticket #1245):
Pull up Xen3 domU support. This adds support for the Xen-3 memory bootstrap,
xenstore, and block and network device frontend. Xen-3 support is turned
on by 'options XEN3', which disable Xen-2 support.
Changes affecting non-xen3 specific code:
- xbd and xennet at hypervisor now attaches with xbd_hypervisor and
  xennet_hypervisor
- x86_atomic_* renamed to xen_atomic_*
- use genassim.cf to pull in more constant from include files for assembly
- Map the shared info page from locore.S instead of the 0xffffffff hack
  in xen_machdep.c
- remove some unused code
- some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline
- more debug code

sync with head.

Snapshot of work in progress on NetBSD port to Xen3:
- kernel (both dom0 and domU) boot, console is functionnal and it can starts
  software from a ramdisk
- there is no driver front-end expect console for domU yet.
- dom0 can probe devices and ex(4) work when Xen3 is booted without acpi
  and apic support. But the on-board IDE doens't get interrupts.
  The PCI code still needs work (it's hardcoded to mode 1). Some of this
  code should be shared with ../x86
  The physical insterrupt code needs to get MPBIOS and ACPI support, and
  do interrupt routing to properly interract with Xen.
To enable Xen-3.0 support, add
options XEN3
to your kernel config file (this will disable Xen2 support)
Changes affecting Xen-2.0 support (no functionnal changes intended):
- get more constants from genassym for assembly code
- remove some unneeded registers move from start()
- map the shared info page from start(), and remove the pte = 0xffffffff hack
- vector.S: in hypervisor_callback() make sure %esi points to
  HYPERVISOR_shared_info before accessing the info page. Remplace some
  hand-written assembly with the equivalent macro defined in frameasm.h
- more debug code, dissabled by default.

while here added my copyright on some files I worked on in 2005.

merge ktrace-lwp.

sync with -current

Sync with HEAD.

sync with head.  xen and whitespace.  xen part is not finished.

file xen.h was added on branch ktrace-lwp on 2005-04-01 14:29:11 +0000

Merge the bouyer-xen2 branch. This add supports for the Xen 2.0 virtual
machine kernel (both privileged and non-privileged domains), and remove support
for the old xen 1.2.

Make shared_info_t volatile.

Public xen2 headers, from the xen 2.0.1 distribution.

file xen.h was initially added on branch bouyer-xen2.
