 powerpc fixes for 4.17 #7
 
 Just one fix, to make sure the PCR (Processor Compatibility Register) is reset
 on boot. Otherwise if we're running in compat mode in a guest (eg. pretending a
 Power9 is a Power8) and the host kernel oopses and kdumps then the kdump
 kernel's userspace will be running in Power8 mode, and will SIGILL if it uses
 Power9-only instructions.
 
 Thanks to:
   Michael Neuling.
