s390: provide interface for service interrupt/introduce interrupt.c
This patch creates interrupt.c. The first user is a callback for hw/*code to trigger an service interrupt for a given sccb value. Severalinterrupt types for s390 are floating (can be delivered to all CPUs)....
target-s390x: Let cpu_s390x_init() return S390CPU
Let cpu_init() return CPUS390XState for backwards compatibility.

s390-virtio: Let s390_cpu_addr2state() return S390CPU
Convert ipi_states to S390CPU**.

s390x: update R and C bits in storage key
When the s390x maps a page or writes happen to a page, the R and Cbits get updated. The easiest way to implement this in qemu is tosimply update them whenever we map a TLB translation and act accordingto the permissions....
s390: Fix cpu shutdown for KVM
On s390 a shutdown is the state of all CPUs being either stoppedor disabled (for interrupts) waiting. We have to track the overallnumber of running CPUs to call the shutdown sequence accordingly.This patch implements the counting and shutdown handling for the...
s390x: Add shutdown for TCG s390-virtio machine
Now that we have code in place to do refcounting of online CPUs, wecan drag the TCG code along and implement shutdown for that one too,so it doesn't feel left out by its KVM counterpart.

Switch build system to accompanied kernel headers
This helps reducing our build-time checks for feature support in theavailable Linux kernel headers. And it helps users that do not havesufficiently recent headers installed on their build machine.
Consequently, the patch removes and build-time checks for kvm and vhost...
s390x: make kvm exported functions conditional on kvm
We have some helper functions we use to directly invoke KVMfunctionality from device emulation code.
This patch replaces those exported functions with static inlinestubs when not building with KVM enabled....
s390x: keep hint on virtio managing size
The s390x virtio bus keeps management information on virtio after the topof the guest's RAM. We need to be able to tell the guest the size of itsRAM (without virtio stuff), but also be able to trap when the guest accesses...
s390x: Shift variables in CPUState for memset(0)
The default reset handler does a memset(0) until right in between CPU_COMMON.I incorrectly changed that behavior on the s390x port, so let's move the fieldsin CPUState around to reflect the correct split up to which point memset(0)...

Because Qemu currently requires a TCG target to exist and there are quite someuseful helpers here to lay the groundwork for out KVM target, let's create astub TCG emulation target for S390X CPUs.
