Subject: [PATCH] ARM: bcm: Don't build brcmstb SMP code when building for V6
Date: Thu, 21 Aug 2014 21:06:34 -0500 [thread overview]
Message-ID: <1408673194-16228-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
The brcmstb SMP code contains isb() and dsb() which are not supported when
building for -march=armv6 as happens when building allmodconfig. Since I
have not been able to identify a way to override the compiler architecture
selection per file add a Kconfig dependency to ensure this code is not
built if V6 support is enabled.
There is doubtless a better solution.
