From fecff0f7243edaea33071865ee5e35839be44f10 Mon Sep 17 00:00:00 2001 From: Mihai Caraman Date: Mon, 6 Aug 2012 03:27:05 +0000 Subject: powerpc/booke64: Add DO_KVM kernel hooks Hook DO_KVM macro into 64-bit booke for KVM integration. Extend interrupt handlers' parameter list with interrupt vector numbers to accomodate the macro. Only the bolted version of tlb miss handers is addressed now.
