Subject: [PATCH 1/5] arm: Move asm macro get_thread_info to asm/assembler.h
Date: Wed, 28 Aug 2013 12:34:20 +0100 [thread overview]
Message-ID: <1377689664-27614-2-git-send-email-catalin.marinas@arm.com> (raw)
In-Reply-To: <1377689664-27614-1-git-send-email-catalin.marinas@arm.com>
asm/assembler.h is a better place for this macro since it is used by
asm files outside arch/arm/kernel/
Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
