in-kernel irqfds for virtio-ccw with adapter interrupts.
Note that s390 doesn't provide the common KVM_CAP_IRQCHIP capability, but
rather needs KVM_CAP_S390_IRQCHIP to be enabled. This is to ensure backward

Commit 40f1ee27aa introduced handy helpers for enable_cap calls on

seem to choke on signedness detection in inline created variables:

However - thanks to Thomas Huth for the suggestion - we can just cast the
offending potentially 0 value to a signed type, making the comparison signed.

Semantics of end_optional() differ subtly from the other end_FOO()
callbacks: when start_FOO() succeeds, the matching end_FOO() gets
called regardless of what happens in between. end_optional() gets
called only when everything in between succeeds as well. Entirely
undocumented, like all of the visitor API.
The only user of Visitor Callback end_optional() never did anything,
and was removed in commit 9f9ab46.
I'm about to clean up error handling in the generated visitor code,
and end_optional() is in my way. No users mean no test cases, and
making non-trivial cleanup transformations without test cases doesn't
strike me as a good idea.
Drop end_optional(), and rename start_optional() to optional(). We
can always go back to a pair of callbacks when we have an actual need.

On the x86, some devices need access to the CPU reset pin (INIT#).
Provide a generic service to do this, using one of the internal
cpu_interrupt targets. Generalize the PPC-specific code for
CPU_INTERRUPT_RESET to other targets.
Since PPC does not support migration across QEMU versions (its
machine types are not versioned yet), I picked the value that
is used on x86, CPU_INTERRUPT_TGT_INT_1. Consequently, TGT_INT_2
and TGT_INT_3 are shifted down by one while keeping their value.

Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset. Using qemu_register_reset
as we do now keeps them far apart.
With this patch, PPC no longer calls the kvm_arch_ function, so
it can get removed there. Other arches call it from their CPU
reset handler, and the function gets an ARMCPU/X86CPU/S390CPU.
Note that ARM- and s390-specific functions are called kvm_arm_*
and kvm_s390_*, while x86-specific functions are called kvm_arch_*.
That follows the convention used by the different architectures.
Changing that is the topic of a separate patch.

still undefined behaviour. We have infrastructure for doing efficient
unaligned accesses which doesn't engage in undefined behaviour, so
use it.
This is technically fractionally less efficient, at least with gcc 4.6;
instead of one instruction:

we get an extra spurious store to the stack slot:

The immediately visible effect of this patch is that it fixes committing
a temporary snapshot to its backing file. Previously, it would fail with
a "permission denied" error because bdrv_inherited_flags() forced the
backing file to be read-only, ignoring the r/w reopen of bdrv_commit().
The bigger problem this revealed is that the original open flags must
actually only be applied to the temporary snapshot, and the original
image file must be treated as a backing file of the temporary snapshot
and get the right flags for that.

previous releases, pc machines up to 2.0 will have their local
apic version set to 0x11.
