From c410b8307702c1e1f35be3fd868ad18e4ba0410f Mon Sep 17 00:00:00 2001 From: Don Zickus Date: Thu, 6 Jan 2011 16:18:50 -0500 Subject: x86, NMI: Remove DIE_NMI_IPI With priorities in place and no one really understanding the difference between DIE_NMI and DIE_NMI_IPI, just remove DIE_NMI_IPI and convert everyone to DIE_NMI. This also simplifies default_do_nmi() a little bit. Instead of calling the die_notifier in both the if and else part, just pull it out and call it before the if-statement. This has the side benefit of avoiding a call to the ioport to see if there is an external NMI sitting around until after the (more frequent) internal NMIs are dealt with.
