From 9009994b06f745e914a74a8e9efb3c5bf3612dd7 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 26 Jul 2011 18:15:03 +0000 Subject: [PATCH] powerpc: pseries: Fix kexec on machines with more than 4TB of RAM commit bed9a31527af8ff3dfbad62a1a42815cef4baab7 upstream. On a box with 8TB of RAM the MMU hashtable is 64GB in size. That means we have 4G PTEs. pSeries_lpar_hptab_clear was using a signed int to store the index which will overflow at 2G.
