Hi stable folks, the patch below fixes kernels 4.4 and 4.9 booting on AMD platforms with PCID support. It doesn't have an upstream counterpart because it patches the KAISER code which didn't go upstream. It applies fine to both of the aforementioned kernels - please pick it up.
Queued up for 4.9 and 4.4, thanks!
Jim Mattson reported that Debian 9 guests using a 4.9-stable kernel are exploding during alternatives patching:
(Cc Ben & Salvatore) I'm not sure if 4.9 or Debian is still alive or not, but FYI... -- Thanks, Sasha
