We don't actually expect that to happen, it's only been seen # on mambo (simulator) in some configurations. # # A zero-size l1d_size leads to the loop in the asm wrapping around to # 2^64-1, and then walking off the end of the fallback area and # eventually causing a page fault which is fatal. # # Just default to 64K which is correct on some CPUs, and sane enough to # not cause a crash on others.
