Hi Janusz!

Nice work overall! Some feedback:

Since we know which platform it is, we know that we applied the previous
get/set multiple patch, so we need not check this if the patches are
applied in sequence.

As long as all patches go in the same merge window, no problem.

I'm BTW ready to apply the get/set multiple patch already.
