From a40343497e8983cdf07fde99c9081ee62b96f745 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 30 Jan 2008 13:34:04 +0100 Subject: [PATCH] x86: fix ioremap pgprot inconsistency The pgprot flags which are handed into ioremap_page_range() are different to those which are set in change_page_attr(). The ioremap_page_range flags are executable, while the c_p_a flags are not. Also make the mappings global (which is a NOP currently on 32bit, although CPUs from PPRO+ onwards support it, but that's a separate fix.)
