Subject: binfmt_flat: Stub in a FLAT_PLAT_INIT().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=74c27c43ebd020fcb65364613503f6c08dc6f535;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

This provides a FLAT_PLAT_INIT() arch hook for platforms that need to set
up specific register state prior to calling in to the process, as per
ELF_PLAT_INIT().
