From e7dd20a398f6048a0855e112e7c1cbd0f1f38e13 Mon Sep 17 00:00:00 2001 From: "Mingarelli, Thomas" Date: Mon, 7 Nov 2011 10:59:00 +0100 Subject: watchdog: hpwdt: Changes to handle NX secure bit in 32bit path commit e67d668e147c3b4fec638c9e0ace04319f5ceccd upstream. This patch makes use of the set_memory_x() kernel API in order to make necessary BIOS calls to source NMIs. This is needed for SLES11 SP2 and the latest upstream kernel as it appears the NX Execute Disable has grown in its control.
