From 325c82a029ca7ea80f8cb24815d6c9288d177190 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 8 Dec 2005 16:51:44 +1100 Subject: [PATCH] [PATCH] powerpc: Fix a huge page bug The 64k pages patch changed the meaning of one argument passed to the low level hash functions (from "large" it became "psize" or page size index), but one of the call sites wasn't properly updated, causing potential random weird problems with huge pages. This fixes it.
