target-s390x: Let cpu_s390x_init() return S390CPU
Let cpu_init() return CPUS390XState for backwards compatibility.

Kill off cpu_state_reset()
In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset()was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all...
target-s390x: Update s390x_{tod,cpu}_timer() to use S390CPU
In place of CPUS390XState pass S390CPU as opaque from the new initfn.cpu_interrupt() is anticipated to take a CPUState in the future.

target-s390x: QOM'ify CPU init
Move code from cpu_s390x_init() into an initfn.
target-s390x: QOM'ify CPU reset
Move code from cpu_state_reset() to s390_cpu_reset().
target-s390x: QOM'ify CPU
Embed CPUS390XState as first member of S390CPU.Since -cpu is being ignored, make TYPE_S390_CPU non-abstract.
target-s390x: Don't overuse CPUState
Scripted conversion: sed -i "s/CPUState/CPUS390XState/g" target-s390x/*.[hc] sed -i "s/#define CPUS390XState/#define CPUState/" target-s390x/cpu.h

Rename cpu_reset() to cpu_state_reset()
Frees the identifier cpu_reset for QOM CPUs (manual rename).
Don't hide the parameter type behind explicit casts, use staticfunctions with strongly typed argument to indirect.

target-s390x: Clean includes
The change in cpu.h is needed when HOST_LONG_BITS is defined in qemu-common.h.

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....
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.

Use glib memory allocation and free functions
qemu_malloc/qemu_free no longer exist after this commit.

Remove unused is_softmmu parameter from cpu_handle_mmu_fault
Parameter is_softmmu (and its evil mutant twin brother is_softmuu)is not used in cpu_*_handle_mmu_fault() functions, remove themand adjust callers.

Avoid allocating TCG resources in non-TCG mode
Do not allocate TCG-only resources like the translation buffer whenrunning over KVM or XEN. Saves a "few" bytes in the qemu address spaceand is also conceptually cleaner.

Remove exec-all.h include directives
Most exec-all.h include directives are now useless, remove them.

target-s390x: Fix build for non-linux hosts
linux/kvm.h is not always available for compilation.
Neither linux/kvm.h nor kvm.h are needed, so remove bothwhich also fixes the build problem for non-linux hosts.

s390x: helper functions for system emulation
When running system emulation, we need to transverse through the MMU anddeliver interrupts according to the specification.
This patch implements those two pieces and in addition adjusts the CPUinitialization code to account for the new fields in CPUState....
s390x: Enable s390x-softmmu target
This patch adds some code paths for running s390x guest OSs without theneed for KVM.

S390: Add stub for cpu_get_phys_page_debug
We don't implement any virtual memory in the S390 target so far, so let'sadd a stub for this now mandatory function.
Fixes building of S390 target.
Large page TLB flush
QEMU uses a fixed page size for the CPU TLB. If the guest uses largepages then we effectively split these into multiple smaller pages, andpopulate the corresponding TLB entries on demand.
When the guest invalidates the TLB by virtual address we must invalidate...
Remove cpu_get_phys_page_debug from userspace emulation
cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it.

Add support for S390x system emulation
Let's enable the basics for system emulation so we can run virtual machineswith KVM!
S/390 CPU fake emulation
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.
This is required to make tcg happy. The emulation target itself won't work...
