Linus Torvalds a56c41e5d7 Two fixes for the generic VDSO code which missed 5.5: 
- Make the update to the coarse timekeeper unconditional. This is required
    because the coarse timekeeper interfaces in the VDSO do not depend on a
    VDSO capable clocksource. If the system does not have a VDSO capable
    clocksource and the update is depending on the VDSO capable clocksource,
    the coarse VDSO interfaces would operate on stale data forever.
 
  - Invert the logic of __arch_update_vdso_data() to avoid further head
    scratching. Tripped over this several times while analyzing the update
    problem above.
