Subject: [PATCH 4.4 33/56] x86/mm: Remove in_nmi() warning from vmalloc_fault()
Date: Tue, 18 Sep 2018 00:42:06 +0200 [thread overview]
Message-ID: <20180917213829.301295044@linuxfoundation.org> (raw)
In-Reply-To: <20180917213827.913122591@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joerg Roedel <jroedel@suse.de>
[ Upstream commit 6863ea0cda8725072522cd78bda332d9a0b73150 ]
It is perfectly okay to take page-faults, especially on the
vmalloc area while executing an NMI handler. Remove the
warning.
