Subject: ARM: EXYNOS: Add flush_cache_all in suspend finisher
X-Git-Tag: v3.8-rc1~136^2~2^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=573e5bbe653d01dc0f27e2d97754db9246b501c8;p=thirdparty%2Fkernel%2Flinux.git

ARM: EXYNOS: Add flush_cache_all in suspend finisher

The core cpu_suspend code no longer calls flush_cache_all to
optimize the cpu idle flow. Add a call for the same in the
exynos specific suspend code.
