kvm: Change prototype of kvm_update_guest_debug()
Passing a CPUState pointer instead of a CPUArchState pointer eliminatesthe last target dependent data type in sysemu/kvm.h.
It also simplifies the code.

kvm: Change kvm_{insert,remove}_breakpoint() argument to CPUState
CPUArchState is no longer directly used since converting CPU loops toCPUState.
Prepares for changing GDBState::c_cpu to CPUState.

kvm: Free current_cpu identifier
Since CPU loops are done as last step in kvm_{insert,remove}_breakpoint()and kvm_remove_all_breakpoints(), we do not need to distinguish betweeninvoking CPU and iterated CPUs and can thereby free the identifier foruse as a global variable....

KVM: Export kvm_init_irq_routing
On PPC, we can have different types of interrupt controllers, so we reallyonly know that we are going to use one when we created it.

This adds a new device that we can use for testing PCI PIO and MMIO, with andwithout ioeventfd in different configurations. FAST_MMIO will be added if/whenkvm supports it. Also included are minor cleanups in kvm APIs that it needs....
cpu: Pass CPUState to cpu_synchronize_post()

Since commit 20d695a9254c1b086a456d3b79a3c311236643ba (kvm: PassCPUState to kvm_arch_*) CPUArchState is no longer needed.

kvm: Pass CPUState to kvm_init_vcpu()

Will be used by virtio-pci.
softmmu: move include files to include/sysemu/
exec: move include files to include/exec/
pci: update all users to look in pci/
update all users so we can remove the makefile hack.
memory: manage coalesced mmio via a MemoryListener
Instead of calling a global function on coalesced mmio changes, whichroutes the call to kvm if enabled, add coalesced mmio hooks toMemoryListener and make kvm use that instead.
The motivation is support for multiple address spaces (which means we...

kvm: Move kvm_allows_irq0_override() to target-i386, fix return type
kvm_allows_irq0_override() is a totally x86 specific concept:move it to the target-specific source file where it belongs.This means we need a new header file for the prototype:kvm_i386.h, in line with the existing kvm_ppc.h....

kvm: Introduce kvm_irqchip_add/remove_irqfd
Add services to associate an eventfd file descriptor as input with anIRQ line as output. Such a line can be an input pin of an in-kernelirqchip or a virtual line returned by kvm_irqchip_add_route.
