Subject: [PATCH v4 07/13] ARM: Move some macros from entry-armv to entry-header
Date: Thu, 19 Jun 2014 11:38:17 +0100 [thread overview]
Message-ID: <1403174303-25456-8-git-send-email-daniel.thompson@linaro.org> (raw)
In-Reply-To: <1403174303-25456-1-git-send-email-daniel.thompson@linaro.org>
From: Anton Vorontsov <anton.vorontsov@linaro.org>
Just move the macros into header file as we would want to use them for
KGDB FIQ entry code.
The following macros were moved:
- svc_entry
- usr_entry
- kuser_cmpxchg_check
- vector_stub
To make kuser_cmpxchg_check actually work across different files, we
also have to make kuser_cmpxchg64_fixup global.
