We don't expect failure here and need 'result' object. cmd() is better

The basic idea of this patch set is to change hw/rtc/mc146818rtc.c into
target independent code so that the file only has to be compiled once
instead of multiple times (and that it can be used in a qemu-system-all

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.

The only reason for this code being target dependent was the IRQ-counting
related code in rtc_policy_slew_deliver_irq(). Since these functions have
been moved into a new, separate file (kvm_irqcount.c) which is now always
compiled and linked if necessary, we can get rid of the #ifdef TARGET_I386

The XEN_EMU option will cover core Xen support in target/, which exists

Xen will "latch" the guest's 32-bit or 64-bit ("long mode") setting when
the guest writes the MSR to fill in the hypercall page, or when the guest

The xen_overlay device (and later similar devices for event channels and

the PC machine derivatives, since KVM is only way to support Xen emulation

The kvm_xen_inject_vcpu_callback_vector() function will either deliver
the per-vCPU local APIC vector (as an MSI), or just kick the vCPU out
of the kernel to trigger KVM's automatic delivery of the global vector.

In emulation, mapping more than one grant ref to be virtually contiguous

On msys2, the shader-to-C script produces bad C:

Fix it by changing the line ending from crlf to lf, and convert the

This is a very early preview of phase 2, in which we make the PV backend
drivers build. Mostly by providing operations tables that can be backed
either by the true Xen toolstack libraries, or by the internal emulated
versions. But also a bunch of untangling of headers to keep things sane.

There's no need for this to be in the Xen accel code, and as we want to
use the Xen console support with KVM-emulated Xen we'll want to have a
platform-agnostic version of it. Make it use GString to build up the
path while we're at it.
