The warning does give a valuable report but it might got lost in compiler

/home/ds/_kernel/linux-2.6-clang/drivers/edac/i7core_edac.c:1673:39: warning:
use of logical && with constant operand; switch to bitwise & or remove constant
        u32 core_err_cnt = (m->status >> 38) && 0x7fff;
                                             ^  ~~~~~~
