From cab0af98dfbbf8076d1af01f2927af491a76a33f Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 3 Nov 2005 15:30:49 +1100 Subject: [PATCH] powerpc: Make set_dabr() a ppc_md function Move pSeries specific code in set_dabr() into a ppc_md function, this will allow us to keep plpar_wrappers.h private to platforms/pseries.
