From 1255166b9974665d1e4a24473e1dc51cd061ef4a Mon Sep 17 00:00:00 2001 From: Bandan Das Date: Fri, 20 May 2016 12:28:35 -0400 Subject: target-i386: add a generic x86 nmi handler Instead of having x86 ifdefs in core nmi code, this change adds a arch specific handler that the nmi common code can call.
