X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b9d6b2a4f6df5544a10de44760755fe757259e5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git sh: Provide a FLAT_PLAT_INIT() definition. SH needs this in order to make sure that r4 has a sane value at process entry time, which the libc expects has already been taken care of. Fixes random crashes in flat binaries.
