Subject: [patch V2 06/64] ktime: Change ktime_set() to take 64bit seconds value
Date: Wed, 16 Jul 2014 21:03:56 -0000	[thread overview]
Message-ID: <20140716205052.671291116@linutronix.de> (raw)
In-Reply-To: 20140716205018.175419210@linutronix.de

[-- Attachment #1: jstultz-tk-696511b.patch --]
[-- Type: text/plain, Size: 1148 bytes --]

From: John Stultz <john.stultz@linaro.org>

In order to support dates past 2038 on 32bit systems, ktime_set()
needs to handle 64bit second values.

[ tglx: Removed the BITS_PER_LONG check ]
