Zachary Amsden c9b02a2413 [PATCH] i386: use set_pte macros in a couple places where they were missing ... Also, setting PDPEs in PAE mode does not require atomic operations, since the PDPEs are cached by the processor, and only reloaded on an explicit or implicit reload of CR3. Since the four PDPEs must always be present in an active root, and the kernel PDPE is never updated, we are safe even from SMIs and interrupts / NMIs using task gates (which reload CR3). Actually, much of this is moot, since the user PDPEs are never updated either, and the only usage of task gates is by the doublefault handler. It appears the only place PGDs get updated in PAE mode is in init_low_mappings() / zap_low_mapping() for initial page table creation and recovery from ACPI sleep state, and these sites are safe by inspection. Getting rid of the cmpxchg8b saves code space and 720 cycles in pgd_alloc on P4.
