From mboxrd@z Thu Jan 1 00:00:00 1970 From: mathieu.poirier@linaro.org (Mathieu Poirier) Date: Thu, 14 Jan 2016 14:46:14 -0700 Subject: [PATCH V8 20/23] perf tools: making function set_max_cpu_num() non static In-Reply-To: <1452807977-8069-1-git-send-email-mathieu.poirier@linaro.org> References: <1452807977-8069-1-git-send-email-mathieu.poirier@linaro.org> Message-ID: <1452807977-8069-21-git-send-email-mathieu.poirier@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org For memory allocation purposes, code located in other places then util/cpumap.c may want to know how many CPUs the system has. This patch is making function set_max_cpu_num() available to other parts of the perf tool so that global variable 'max_cpu_num' gets the right value when referenced by cpu__max_cpu().
