Switch the user dirty bit detection used for migration from the hardware provided host change-bit in the pgste to a fault based detection method. This reduced the dependency of the host from the storage key to a point where it becomes possible to enable the RCP bypass for KVM guests. The fault based dirty detection will only indicate changes caused by accesses via the guest address space. The hardware based method can detect all changes, even those caused by I/O or accesses via the kernel page table. The KVM/qemu code needs to take this into account.
