[master][PATCH 1/2 v2] kernel.bbclass: Pull in kernel.bbclass from oe-core master

[Franklin S. Cooper Jr]

* Pull in kernel.bbclass from oe-core master to allow patching of the local
  version of kernel.bbclass until upstream patch is accepted and pulled into
  oe-core master.

Re: [master][PATCH 1/2 v2] kernel.bbclass: Pull in kernel.bbclass from oe-core master

Re: [master][PATCH 1/2 v2] kernel.bbclass: Pull in kernel.bbclass from oe-core master

Yes, I understand that. But at the same time meta-ti is used much wider and 
overlaying a core class is very risky and not recommended. Previously we also 
had rather generic fixes applied to kernel.bbclass and still kept it in 
meta-arago...
