#     powerpc/64s: Set reserved PCR bits
#     
#     Currently the reserved bits of the Processor Compatibility
#     Register (PCR) are cleared as per the Programming Note in Section
#     1.3.3 of version 3.0B of the Power ISA. This causes all new
#     architecture features to be made available when running on newer
#     processors with new architecture features added to the PCR as bits
#     must be set to disable a given feature.
#     
#     For example to disable new features added as part of Version 2.07 of
#     the ISA the corresponding bit in the PCR needs to be set.
#     
#     As new processor features generally require explicit kernel support
#     they should be disabled until such support is implemented. Therefore
#     kernels should set all unknown/reserved bits in the PCR such that any
#     new architecture features which the kernel does not currently know
#     about get disabled.
#     
#     An update is planned to the ISA to clarify that the PCR is an
#     exception to the Programming Note on reserved bits in Section 1.3.3.
