From: Jason Cooper Date: Mon, 24 Mar 2014 02:32:49 +0000 (+0000) Subject: staging: crypto: skein: allow building statically X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c2c7426bfcf2473ed4cf7135c2b15bae9c13dd6e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: crypto: skein: allow building statically These are the minimum changes required to get the code to build statically in the kernel. It's necessary to do this first so that we can empirically determine that future cleanup patches aren't changing the generated object code.
