PROFILE_NMI kernel config symbol

[John Sigler]

Hello,

The -rt patch includes the following update:

Index: linux/arch/i386/oprofile/Kconfig
===================================================================
--- linux.orig/arch/i386/oprofile/Kconfig
+++ linux/arch/i386/oprofile/Kconfig
@@ -15,3 +15,6 @@ config OPROFILE

 	  If unsure, say N.

+config PROFILE_NMI
+	bool
+	default y


What is the purpose of the PROFILE_NMI config symbol?
(It does not seem to be used anywhere else in the -rt patch.)

Regards.
