#     powerpc: Fix P10 PVR revision in /proc/cpuinfo for SMT4 cores
#     
#     On POWER10 bit 12 in the PVR indicates if the core is SMT4 or
#     SMT8. Bit 12 is set for SMT4.
#     
#     Without this patch, /proc/cpuinfo on a SMT4 DD1 POWER10 looks like
#     this:
#         cpu             : POWER10, altivec supported
#         revision        : 17.0 (pvr 0080 1100)
