      [PATCH] set default video mode on PowerBook Wallstreet · 3b46f039
      Olaf Hering authored
      Finally add the third PowerBook Wallstreet 233MHz model to the list of
      known display resolutions.
      
      Without this change, a 640x480 video mode is used.  A workaround so far was
      to boot with 'video=atyfb:vmode:14'

      [PATCH] eCryptfs: dput() lower d_parent on rename · a9083081
      Michael Halcrow authored
      On rename, for both the old and new lower dentry objects, eCryptfs is
      missing a dput on the lower parent directory dentry.  This patch will
      prevent the BUG() at fs/dcache.c:613 from being hit after renaming a file
      inside eCryptfs and then doing a umount on the lower filesystem.

       <0>Kernel panic - not syncing: Aiee, killing interrupt handler!
      
      The root cause is that some irq_chip variables, especially ia64_msi_chip,
      initiate their memeber end to point to NULL. __do_IRQ doesn't check
      if irq_chip->end is null and just calls it after processing the interrupt.
      
      As irq_chip->end is called at many places, so I fix it by reinitiating
      irq_chip->end to dummy_irq_chip.end, e.g., a noop function.

      The root cause is the device struct is initialized twice.
      
      If the device is allocated dynamically by platform_device_alloc,
      platform_device_alloc will initialize struct device, then,
      platform_device_add should be used to register the device.
      
      The difference between platform_device_register and platform_device_add is
      platform_device_register will initiate the device while platform_device_add
      won't.

      [PATCH] powerpc: windfarm shall request it's sub modules · d31e8171
      Benjamin Herrenschmidt authored
      The windfarm code, in it's current incarnation, uses request_module() to
      load the various submodules it needs for a given platform so that only
      the main platform control module needs to be modprobed. However, it was
      missing various bits. This fixes it. In the future, we'll use some
      hotplug mecanisms to try to get all of this auto-loaded on the platforms
      where it matters but that isn't ready yet.
