But it is in lib/vsprintf.c:
...
644 /*
645 * Show a '%p' thing. A kernel extension is that the '%p' is followed
646 * by an extra set of alphanumeric characters that are extended format
647 * specifiers.
648 *
649 * Right now we handle:
650 *
651 * - 'F' For symbolic function descriptor pointers
652 * - 'S' For symbolic direct pointers
653 * - 'R' For a struct resource pointer, it prints the range of
654 * addresses (not the name nor the flags)
655 * - 'M' For a 6-byte MAC address, it prints the address in the
656 * usual colon-separated hex notation
657 * - 'I' [46] for IPv4/IPv6 addresses printed in the usual way
(dot-separated
658 * decimal for v4 and colon separated network-order 16 bit hex for
v6)
659 * - 'i' [46] for 'raw' IPv4/IPv6 addresses, IPv6 omits the colons, IPv4 is
660 * currently the same
...
So it's actually printk("%pM", ...);
Best regards,
Wolfgang Denk
