#     powerpc/64s: Clear PCR on boot
#     
#     Clear the PCR (Processor Compatibility Register) on boot to ensure we
#     are not running in a compatibility mode.
#     
#     We've seen this cause problems when a crash (and kdump) occurs while
#     running compat mode guests. The kdump kernel then runs with the PCR
#     set and causes problems. The symptom in the kdump kernel (also seen in
#     petitboot after fast-reboot) is early userspace programs taking
#     sigills on newer instructions (seen in libc).
