| |
Changes since V3: - Avoid for_each_online_cpu() search for per package MSR access. This is achieved by tracking a per package lead cpu via cpumask_xx() calls. (suggested by Thomas Gleixner <tglx@linutronix.de>) - Add direct reference of RAPL package for each RAPL domain.
This patch optimize remote IPI calls for MSR access.
