By this, do you mean the kernel source tree ? Or the layers ?

I haven't looked at the kernel recipe you are using, but PV
and the git hash you have in those package names is coming from
the kernel source directory.

It is there that you'll likely find un-commited changes, and what
is triggering the -dirty flag to be captured.
