Sorry, that's a bummer that these patches were reverted.  :(  The whole
episode was a bit unfortunate...

Qualcom has been working on those patches for a year.  They must not be
using kunit testing as part of their QC...  It's some kind of
communication failure on our part.

Hopefully we can get this all sorted out and re-apply the patches soon.
