From dd7a5ab495019d424c2b0747892eb2e38a052ba5 Mon Sep 17 00:00:00 2001 From: Daniel J Blueman Date: Thu, 31 Dec 2015 02:06:47 +0800 Subject: x86/numachip: Fix NumaConnect2 MMCFG PCI access The MMCFG PCI accessors weren't being setup for NumacConnect2 correctly due to over-early assignment; this would create the potential for the wrong PCI domain to be accessed. Fix this by using the correct arch-specific PCI init function.
