This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: gtod: fix timeout overflow
From: Ingo Molnar <mingo@xxxxxxx>
Prevent timeout overflow if timer ticks are behind jiffies (due to high
softirq load or due to dyntick), by limiting the valid timeout range to
MAX_LONG/2.
