s390x: fix memory detection for guests > 64GB
the s390 memory detection has a 16bit field that specifies the amount ofincrements. This patch adopts the memory size to always fit into thatscheme. This also fixes virtio detection for these guests, since the...
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: Implement opcode helpers
There are some instructions that can't (or shouldn't) be expressed by puretcg code. For those, we call into externally compiled C functions.
This patch implements those C functions.

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...
