Subject: [PATCH 069/105] drivers/perf: arm_pmu_platform: do not warn about
affinity on uniprocessor
Git-commit: 65bd053fbf46c44b9862cb1e7d76ee84f90e386e
Patch-mainline: v4.17-rc1
References: fate#325865,fate#325861
If there is exactly one CPU present, there is no ambiguity: do not warn
that PMU setup would need to guess IRQ affinity.
