In is_module_segment(), when VMALLOC_END is over 0xf0000000, ALIGN(VMALLOC_END, SZ_256M) has value 0. In that case, addr >= ALIGN(VMALLOC_END, SZ_256M) is always true then is_module_segment() always returns false. Use (ALIGN(VMALLOC_END, SZ_256M) - 1) which will have value 0xffffffff and will be suitable for the comparison.
