This results in integer overflows and eventualy NTP getting out of sync. According to the history the sanity checks had been removed in favor of clamping the values, but the clamping never worked correctly under all circumstances. The NTP people asked to not bring the sanity checks back as it might break existing applications. Make the clamping work correctly and add it where it's missing - If adjtimex() sets the clock it has to trigger the hrtimer subsystem so it can adjust and if the clock was set into the future expire timers if needed. The caller should provide a bitmask to tell hrtimers which clocks have been adjusted. adjtimex() uses not the proper constant and uses CLOCK_REALTIME instead, which is 0. So hrtimers adjusts only the clocks, but does not check for expired timers, which might make them expire really late. Use the proper bitmask constant instead.

Setting read only on 32-bit might break up the PMD mapping, which makes the second invocation of pti_clone_entry_text() find the mappings out of sync and failing. Allow the second call to split the existing PMDs in the user mapping and synchronize with the kernel mapping. - Don't make acpi_mp_wake_mailbox not read only after init as the mail box must be writable in the case that CPU hotplug operations happen after boot. Otherwise the attempt to start a CPU crashes with a write to read only memory. - Add a missing sanity check in mtrr_save_state() to ensure that the fixed MTRR MSRs are supported. Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but the WARN_ON() can bring systems down when panic on warn is set.
