S390: Add stub for cpu_get_phys_page_debug

We don't implement any virtual memory in the S390 target so far, so let's
add 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 large
pages then we effectively split these into multiple smaller pages, and
populate 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.

Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha. This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place....

KVM: Rework VCPU state writeback API

This grand cleanup drops all reset and vmsave/load related
synchronization points in favor of four(!) generic hooks:

- cpu_synchronize_all_states in qemu_savevm_state_complete
(initial sync from kernel before vmsave)...

Fix incorrect exception_index use

env->exception_index should be cleared with -1, not 0.

target-s390: Fail on unknown instructions

We were being a bit too nice and didn't give the guest an invalid instruction
interrupt.

While that works, it's not exactly the fastest thing to do, since now the
guest doesn't know that we're not really implementing that instruction, so it...
