I found two more using "git grep 'define.*0x[0-9a-f]* < '":
drivers/net/can/m_can/m_can.c:#define RXFC_FWM_MASK (0x7f < RXFC_FWM_SHIFT)
drivers/usb/gadget/udc/goku_udc.h:#define INT_EPnNAK(n)
(0x00100 < (n)) /* 0 < n < 4 */

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
