Hi,

Any feedback on these two fixes?

Along with a two more fixes to follow in a few mins these are needed for the 
region code
in Linux 6.0-rc1 to work (there is a kernel fix as well that came from testing 
against
QEMU).

For full support we need one more feature (serial number provisioning) but 
without that
we get regions working as long as you create them fresh on each boot.

Thanks,

Jonathan
