Default Update to Stable Kernel

Hi All,


The stable kernel has recently been released.


The upstream stable kernel brings in 14 patches. Two patches
from upstream were excluded before in Ubuntu as they
introduced a regression. The fix for the regression is included in the
upstream patch-set. I've applied and pushed these two patches
from upstream and all the patches from upstream to
my tree for review.

The 14 stable patches are as follows. I've inlined my own review
comments (marked by #).

Thanks !

Warm Regards,
