Subject: [PATCH] clockevents: make register functions work on UP
Date: Wed, 1 Jun 2011 10:49:43 +0200 [thread overview]
Message-ID: <mailman.0.1306918392.5904.linux-arm-kernel@lists.infradead.org> (raw)
On UP systems the clkevt->cpumask is not required, and so as to
avoid ifdef:ing it out of the struct on UP, we remove the mask
warning on UP and force the mask to CPU0 for consistency.
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
