With XIP kernel, kernel_map.size is set to be only the size of data part of the kernel. This is inconsistent with "normal" kernel, who sets it to be the size of the entire kernel. More importantly, XIP kernel fails to boot if CONFIG_DEBUG_VIRTUAL is enabled, because there are checks on virtual addresses with the assumption that kernel_map.size is the size of the entire kernel (these checks are in arch/riscv/mm/physaddr.c). Change XIP's kernel_map.size to be the size of the entire kernel.
