Some of the Linux PCI functions called by the virtual configuration
space handlers were making calls into ACPI code which uses semaphores.
Since semaphores can not be locked while atomic (because they could
sleep), I changed the way the PCI backend responds to requests from the
frontend. Previously, the virtual configuration space handlers ran in
the same context as the event channel interrupt handler (which was often
atomic if not always atomic). Now the interrupt handler schedules a
callback function (a bottom half) in the system work queue (keventd)
that will get called in process context at a slightly later time. This
allows the handlers in the virtual configuration space to run in process
context and to call any core PCI function regardless of whether it will
sleep or not.

This patch adds a policy name to the policy definition. This policy name
must be unique and must change if the content of the file changes. The
policy name is used to ensure that the XM tools and the hypervisor work
on the same policy, i.e., interpret the security information on domains
consistently. This patch also simplifies the policy management by moving
policy and labels into a single file.

The Xen checksum offload feature attempts to insert a TCP/UDP
checksums into already encrypted packets (esp4) in dom0. Obviously,
it is not possible to insert a checksum into an already encrypted
packet, so this patch inserts the checksum prior to encrypting
packets in net/ipv4/xfrm4_output.c.
To do this cleanly, the TCP/UDP header pointers need to be pointed to
the correct spot, so this functionality has been abstracted into a new
function.
This patch fixes bug 143 (verified by Jim Dykman). Earlier version
verified by Jon McCune.

Avoid flood of PIT interrupts while debugging an hvm guest.
This is rebased to the new PIT code now. It has the same logic as
earlier. PIT tries to catch up the missed timer ticks by injected all
the ticks one by one so that Guest time stays close to the wall clock.
But while debugging a hvm guest if you stop the guest by debugger and
then continue, the guest sees flood of interrupts compensating the
missed ticks for the stopped time. This patch just check if the guest is
being debugged, if yes then it does not try to catch up with the missed
ticks.

[IA64] Add support to physdev_ops
Add support to physdev ops, and thus give IOSAPIC RTEs
managed by Xen now. Dom0 now issues hypercall to r/w
RTE entry. Another change is the irq vector allocation
which is also owned by xen now.
After this change, the IOSAPIC is almost owned by xen
with only exception as IOSAPIC EOI which is still issued
by dom0 directly. But that's OK since currently dom0
owns all external physical devices. Later full event
channel mechanism will provide necessary support for
driver domain, and at that time, dom0 instead issues
physdev_op (PHYSDEVOP_IRQ_UNMASK_NOTIFY) naturally as
replace of IOSAPIC EOI.
