[PATCH] make bad_page() print all of page->flags
bad_page() only prints out 8 hexadecimal digits of page->flags regardless
of sizeof(page_flags_t). This leads to confusing and/or incomplete bug
reports. The following patch uses a field width argument to replace the
hardcoded %08lx so that bad_page() may print the whole of page->flags.
