From 92b5a1545ad51e8225e691e9a29ba33cc9fe37bc Mon Sep 17 00:00:00 2001 From: Kyle Meyer Date: Tue, 27 Aug 2019 16:43:48 -0500 Subject: [PATCH] perf stat: Replace MAX_NR_CPUS with cpu__max_cpu() The function cpu__max_cpu() returns the possible number of CPUs as defined in the sysfs and can be used as an alternative for MAX_NR_CPUS in zero_per_pkg() and check_per_pkg().
