#     powerpc/pseries: export timebase register sample in lparcfg
#     
#     The Processor Utilzation of Resource Registers (PURR) provide an
#     estimate of resources used by a cpu thread. Section 7.6 in Book III of
#     the ISA outlines how to calculate the percentage of shared resources
#     for threads using the ratio of the PURR delta and Timebase Register
#     delta for a sampled period.
#     
#     This calculation is currently done erroneously by the lparstat tool
#     from the powerpc-utils package. This patch exports the current
#     timebase value after we sample the PURRs and exposes it to userspace
#     accounting tools via /proc/ppc64/lparcfg.
