From 42222eae17f7c930833dfda7896ef280879de94a Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Thu, 23 Jan 2020 10:41:16 -0800 Subject: mm: remove arch_bprm_mm_init() hook From: Dave Hansen MPX is being removed from the kernel due to a lack of support in the toolchain going forward (gcc). arch_bprm_mm_init() is used at execve() time. The only non-stub implementation is on x86 for MPX. Remove the hook entirely from all architectures and generic code.
