Subject: [RFC] suspicious code in frv/kernel/traps.c

In insn_access_error():
        info.si_addr    = (void *) ((epcr0 & EPCR0_V) ? (epcr0 & EPCR0_PC) : __frame->pc);

In illegal_instruction():
        info.si_addr    = (void *) ((epcr0 & EPCR0_PC) ? (epcr0 & EPCR0_PC) : __frame->pc);

and with

#define EPCR0_V                 0x00000001      /* register content validity indicator */
#define EPCR0_PC                0xfffffffc      /* faulting instruction address */

it really smells like a braino in the latter...
