These functions should be used for e.g. interrupt handlers where no guest memory access protection facilities, like key or low address protection, are applicable. At a later point guest vcpu lowcore access should happen via pinned prefix pages, so that these pages can be accessed directly via the kernel mapping. All of these *_lc functions can be removed then.
