Subject: [PATCH v2 2/3] ARM: omap4: Correct definition of do_wfi() for CONFIG_THUMB2_KERNEL
Date: Mon, 6 Dec 2010 17:35:36 +0000 [thread overview]
Message-ID: <1291656937-24992-3-git-send-email-dave.martin@linaro.org> (raw)
In-Reply-To: <1291656937-24992-1-git-send-email-dave.martin@linaro.org>
For the Thumb-2 case, the "wfi" mnemonic is used, since in this
case the tools will necessarily be new enough to support it.
