[PATCH 5/5] MIPS: perf: Fold vpe_id() macro into it's one last usage

From: Matt Redfearn
Date: Tue Apr 03 2018 - 08:36:54 EST


The vpe_id() macro is now used only in mipsxx_pmu_enable_event when
CONFIG_CPU_BMIPS5000 is defined. Fold the one used definition of the
macro into it's usage and remove the now unused definitions.
