Right now we configure the pagesize quite early, when initializing KVM. This is long before system memory is actually allocated via memory_region_allocate_system_memory(), and therefore memory backends marked as mapped. Instead, let's configure the maximum page size after initializing memory in s390_memory_init(). cap_hpage_1m is still properly configured before creating any CPUs, and therefore before configuring the CPU model and eventually enabling CMMA. This is not a fix but rather a preparation for the future, when initial memory might reside on memory backends (not the case for s390x right now) We will replace qemu_getrampagesize() soon by a function that will always return the maximum page size (not the minimum page size, which only works by pure luck so far, as there are no memory backends).
