From 2df7a6e9e8e67c19e5fe2eac3f2d2223b7bb4a7b Mon Sep 17 00:00:00 2001 From: Brian Gerst Date: Fri, 3 Sep 2010 21:17:08 -0400 Subject: [PATCH] x86: Use correct type for %cr4 %cr4 is 64-bit in 64-bit mode (although the upper 32-bits are currently reserved). Use unsigned long for the temporary variable to get the right size.
