From 584f8b71a2e8abdaeb4b6f4fddaf542b61392453 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Thu, 6 Dec 2007 17:24:48 +1100 Subject: [POWERPC] Use SLB size from the device tree Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.
