From 74c93f9d39b556ff9ac2340d568ad5caf8446c65 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Tue, 14 Jan 2014 10:25:53 -0600 Subject: x86/uv/nmi: Fix Sparse warnings Make uv_register_nmi_notifier() and uv_handle_nmi_ping() static to address sparse warnings. Fix problem where uv_nmi_kexec_failed is unused when CONFIG_KEXEC is not defined.
