From bff63471ced94e3a6de76b1a7375a875178d6cdc Mon Sep 17 00:00:00 2001 From: Qiao Nuohan Date: Thu, 30 May 2013 17:07:54 +0200 Subject: [PATCH] target-i386: Fix mask of pte index in memory mapping MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Function walk_pte() needs pte index to calculate virtual address. However, pte index of PAE paging or IA-32e paging is 9 bit, so the mask should be 0x1ff.
