On PowerVM and KVM on Power use the new memory allocation function that honors restrictions on which memory GRUB can actually use. In the request structure indicate the request for a single memory block along with address alignment restrictions. Request direct usage of the memory block by setting init_region to false (prevent it from being added to GRUB's heap). Initialize the found addr to -1, so that -1 will be returned to the loader in case no memory could be allocated. Report an out-of-memory error in case the initrd could not be loaded.
