The patch titled
ntp: remove time_tolerance
has been removed from the -mm tree. Its filename is
ntp-remove-time_tolerance.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ntp: remove time_tolerance
From: Roman Zippel <zippel@xxxxxxxxxxxxxx>
time_tolerance isn't changed at all in the kernel, so simply remove it, this
simplifies the next patch, as it avoids a number of conversions.
