Subject: [PATCH] x86/power/64: Use __pa() for physical address computation
Date: Sun, 14 Aug 2016 04:07:32 +0200	[thread overview]
Message-ID: <5387760.qC5CG883jv@vostro.rjw.lan> (raw)

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The value of temp_level4_pgt is the physical address of the
top-level page directory, so use __pa() to compute it.
