      Input: inport, logibm - use KERN_INFO when reporting missing mouse · 2a0f9c4c
      由 Helge Deller 提交于 
      Many mouse drivers are often compiled (e.g. in Linux distributions) into the
kernel at the same time just to make sure that at least one driver will suceed
in find it's mouse device. Nevertheless, only the inport and logitech busmouse
mouse drivers report with KERN_ERR log level if the mouse wasn't found. They
should use KERN_INFO instead, because it's not an error if the mouse isn't
attached at all.

      Input: appletouch - idle reset logic broke older Fountains · 2a3e480d
      由 Dmitry Torokhov 提交于 
      Fountains do not support change mode request and therefore
should be excluded from idle reset attempts.

Also:
 - do not re-submit URB when we decide that touchpad needs to be
   reinicialized
 - do not repeat size detection when reinitializing the touchpad
 - Add missing KERN_* prefixes to messages

      Fix myri10ge NAPI oops & warnings · c956a240
      由 Andrew Gallatin 提交于 
      When testing the myri10ge driver with 2.6.24-rc1, I found
that the machine crashed under heavy load:

Unable to handle kernel paging request at 0000000000100108 RIP:
  [<ffffffff803cc8dd>] net_rx_action+0x11b/0x184

The address corresponds to the list_move_tail() in
netif_rx_complete():
                     if (unlikely(work == weight))
                             list_move_tail(&n->poll_list, list);

Eventually, I traced the crashes to calling netif_rx_complete() with
work_done == budget.  From looking at other drivers, it appears that
one should only call netif_rx_complete() when work_done < budget.

To fix it, I changed the test in myri10ge_poll() so that it refers
to to work_done rather than looking at the rx ring status.  If
work_done is < budget, then that implies we have no more packets to
process. Any races will be resolved by the NIC when the write to
irq_claim is made.

In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would
report a work_done one larger than was acutally done.  This is because
the increment was done in the conditional, so work_done would be
incremented regardless of whether or not the test passed or failed.
This would lead to the WARN_ON_ONCE(work > weight); warning in
net_rx_action triggering.  I've moved the increment of work_done
inside the loop.  Note that this would only be a problem when we had
exceeded our budget.

      Fix region size check in mpc5200 FEC driver · 48d58459
      由 Grant Likely 提交于 
      Driver shouldn't complain if the register range is larger than what
it expects.  This works around failures with some device trees.

      mpc5200: Fix Kconfig dependancies on MPC5200 FEC device driver · 644fdf9b
      由 Grant Likely 提交于 
      When not building an arch/powerpc kernel, the mpc5200 FEC driver depends
on some symbols which are not defined (BESTCOMM & BESTCOMM_FEC).

This patch flips around the dependancy logic so that it cannot be
selected unless BESTCOMM_FEC is selected first.  Kconfig stops
complaining this way.

Also, the driver only works for arch/powerpc (not arch/ppc) anyway so
it should depend on PPC_MERGE also.
