Subject: [PATCH 3.13 16/40] arm64: add DSB after icache flush in __flush_icache_all()
Date: Tue, 18 Feb 2014 14:47:17 -0800 [thread overview]
Message-ID: <20140218224433.794602875@linuxfoundation.org> (raw)
In-Reply-To: <20140218224433.337299968@linuxfoundation.org>
3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vinayak Kale <vkale@apm.com>
commit 5044bad43ee573d0b6d90e3ccb7a40c2c7d25eb4 upstream.
Add DSB after icache flush to complete the cache maintenance operation.
The function __flush_icache_all() is used only for user space mappings
and an ISB is not required because of an exception return before executing
user instructions. An exception return would behave like an ISB.
