Subject: x86/MCE: Remove min interval limitation
Date: Mon, 16 Jul 2018 10:49:27 +0200	[thread overview]
Message-ID: <20180716084927.24869-1-alexander.sverdlin@nokia.com> (raw)

From: Dewet Thibaut <thibaut.dewet@nokia.com>

Previously the min interval limitation (one second) has been introduced.
In this case it was no longer possible to disable the machine check.
This patch removes this limitation and allows the value 0 again.
