When running system emulation, we need to transverse through the MMU and deliver interrupts according to the specification. This patch implements those two pieces and in addition adjusts the CPU initialization code to account for the new fields in CPUState. Signed-off-by: NAlexander Graf <agraf@suse.de>

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. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

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 all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: NPaul Brook <paul@codesourcery.com>

cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it. Signed-off-by: NPaul Brook <paul@codesourcery.com>

Let's enable the basics for system emulation so we can run virtual machines with KVM! Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

Because Qemu currently requires a TCG target to exist and there are quite some useful helpers here to lay the groundwork for out KVM target, let's create a stub TCG emulation target for S390X CPUs. This is required to make tcg happy. The emulation target itself won't work though. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>
