      thp: fix khugepaged defrag tunable documentation · e369fde1
      David Rientjes authored
      Commit e27e6151 ("mm/thp: use conventional format for boolean
      attributes") changed
      
        /sys/kernel/mm/transparent_hugepage/khugepaged/defrag
      
      to be tuned by using 1 (enabled) or 0 (disabled) instead of "yes" and
      "no", respectively.
      
      Update the documentation.

      zorro: Defer device_register() until all devices have been identified · a7f4d00a
      Geert Uytterhoeven authored
      As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro
      devices can contain only one BAR, several Amiga Zorro II expansion
      boards (mainly graphics cards) contain multiple Zorro devices: a small
      one for the control registers and one (or more) for the graphics memory.
      
      The conversion of cirrusfb to the new driver framework introduced a
      regression: the driver contains a zorro_driver for the first Zorro
      device, and uses the (old) zorro_find_device() call to find the second
      Zorro device.
      
      However, as the Zorro core calls device_register() as soon as a Zorro
      device is identified, it may not have identified the second Zorro device
      belonging to the same physical Zorro expansion card.  Hence cirrusfb
      could no longer find the second part of the Picasso II graphics card,
      causing a NULL pointer dereference.
      
      Defer the registration of Zorro devices with the driver framework until
      all Zorro devices have been identified to fix this.
      
      Note that the alternative solution (modifying cirrusfb to register a
      zorro_driver for all Zorro devices belonging to a graphics card, instead
      of only for the first one, and adding a synchronization mechanism to
      defer initialization until all have been found), is not an option, as on
      some cards one device may be optional (e.g.  the second bank of 2 MiB of
      graphics memory on the Picasso IV in Zorro II mode).
