[PATCH] perf c2c: Fix report with offline cpus
From: Ravi Bangoria
Date: Thu Aug 22 2019 - 09:44:53 EST
If c2c is recorded on a machine where any cpus are offline,
'perf c2c report' throws an error "node/cpu topology bugFailed
setup nodes". It fails because while preparing node-cpu mapping
we don't consider offline cpus.
Fixes: 1e181b92a2da ("perf c2c report: Add 'node' sort key")
