No, no no. We should never export PAGE_SIZE. We might export NBPG as deprecated symbol for gdb if it really needs it, but that should happen only on a.out systems, and it it should be a true constant, not depending on PAGE_SIZE. I've Cc'ed the gdb list on whether they have any comments on this issue. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
