Subject: [PATCH 01/11] cris: move usec/nsec conversion to do_slow_gettimeoffset
Date: Thu,  8 Nov 2012 14:01:46 -0700	[thread overview]
Message-ID: <1352408516-21988-3-git-send-email-swarren@wwwdotorg.org> (raw)
In-Reply-To: <1352408516-21988-1-git-send-email-swarren@wwwdotorg.org>

From: Stephen Warren <swarren@nvidia.com>

Move usec to nsec conversion from arch_gettimeoffset() to
do_slow_gettimeoffset(); in a future patch, do_slow_gettimeoffset()
will be used directly as the implementation of arch_gettimeoffset(),
so needs to perform all required calculations.
