Subject: [PATCH] x86,nmi: Fix the type of nmiaction.flags field

From: Betty Dall <betty.dall@...com>

This patch changes the type of the struct nmiaction flags field to
unsigned long from unsigned int. All the usages of the flags field
are unsigned long already. There is only one flag used currently,
NMI_FLAG_FIRST, but having the wrong size could cause a truncation
bug in the future on 64 bit architectures.
