Subject: [GIT PULL] x86/debug change for v4.13
Date: Mon, 3 Jul 2017 11:06:31 +0200	[thread overview]
Message-ID: <20170703090630.z77wxaaxkl7ngjg2@gmail.com> (raw)

Linus,

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-debug-for-linus

   # HEAD: c133c7615751008f6c32ccae7cdfc5ff6e989c35 x86/nmi: Fix timeout test in test_nmi_ipi()

A single fix for an off-by one bug in test_nmi_ipi() that probably doesn't matter 
in practice.

 Thanks,

	Ingo
