I've been experimenting, the upgrades look good but we have a problem
with the new kernel class changes.

The issue is that if you have an existing TMPDIR, the build will do "bad
things".

Basically, there is usually an existing sstate manifest file which
covers the kernel source in the sysroot. do_configure will trigger
cleaning of that manifest, a large chunk of the source disappears and
then the build understandably fails.

Whilst I can say what is happening, I can't say how we fix it at this
point :/.

I would like people to test these patches, we'd better hold off merging
until we can get this issue figured out. Its part of a wider problem
with "stale" data in the sysroot which we really need to figure out but
its not been solved yet as its a  very hard problem for which we don't
have a solution :(.

Cheers,

Richard
