I've discovered that we're not the only one to miss dirty / accessed "hardware" bits: see include/asm-alpha/pgtable.h (they don't have the accessed bit). So maybe we could drop the "fault-on-access" thing. Also, note the comment before handle_pte_fault: /* * These routines also need to handle stuff like marking pages dirty * and/or accessed for architectures that don't do it in hardware (most * RISC architectures). The early dirtying is also good on the i386. */ I'm not able to find where we clean the dirty bit on a pte, however it's not only done by pte_mkclean, there are some macros like ptep_clear... in asm-generic/pgtable.h -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
