[PATCH] perf tool: Set JOBS based on CPU or processor

From: David Ahern
Date: Tue Mar 24 2015 - 12:11:14 EST


Number of JOBS to use is set automatically to the number of processors found
in /proc/cpuinfo. SPARC uses 'CPU' lines rather than 'processor'. Update the
check in perf's Makefile to work for SPARC.
