From: Anton Blanchard Date: Tue, 26 Jul 2011 18:15:03 +0000 (+0000) Subject: powerpc: pseries: Fix kexec on machines with more than 4TB of RAM X-Git-Tag: v2.6.32.45~1 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2b3fde0c9bedb784f48c12b9980594a7f8a0d187;p=karo-tx-linux.git 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.
