Subject: [PATCH v6 0/4] powercap/rapl: reduce ipi calls and misc clean up

Changes since v5:
	- Split changes into seprate patches. No code change.
Changes since V4:
	- Deleted unnecessary cpumask_any_and() call, assign first cpu as lead
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@...utronix.de>)
	    - Add direct reference of RAPL package for each RAPL domain.

Jacob Pan (4):
  cpumask: export cpumask_any_but
  powercap/rapl: reduce ipi calls
  powercap/rapl: add package reference per domain
  powercap/rapl: track lead cpu per package
