[RFC PATCH 10/10] timer: Lower base clock forwarding threshold

From: Frederic Weisbecker
Date: Tue Jun 30 2020 - 21:10:59 EST


There is no apparent reason for not forwarding base->clk when it's 2
jiffies late, except perhaps for past optimizations. But since forwarding
has to be done at some point now anyway, this doesn't stand anymore.
