From mboxrd@z Thu Jan 1 00:00:00 1970 From: amit.kachhap@linaro.org (Amit Daniel Kachhap) Date: Tue, 21 Feb 2012 11:49:49 +0530 Subject: [PATCH V6 4/5] ARM: exynos: remove useless code to save/restore L2 In-Reply-To: <1329805190-8874-1-git-send-email-amit.kachhap@linaro.org> References: <1329805190-8874-1-git-send-email-amit.kachhap@linaro.org> Message-ID: <1329805190-8874-5-git-send-email-amit.kachhap@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Following the merge of CPU PM notifiers and L2 resume code, this patch removes useless code to save and restore L2 registers. This is now automatically covered by suspend calls which integrated CPU PM notifiers and new sleep code that allows to resume L2 before MMU is turned on.
