I have the kgdb regression builder running right now (it will be done in about 1 hour), and so far it picked up one new warning.

drivers/tty/serial/kgdb_nmi.c: In function 'kgdb_nmi_poll_one_knock':
drivers/tty/serial/kgdb_nmi.c:161: warning: field width should have type 'int', but argument 4 has type 'size_t'
