From d1be5c99a0341249bf6f74eb1cbc3d5fc4ef2be7 Mon Sep 17 00:00:00 2001 From: Yury Norov Date: Sun, 20 Aug 2017 13:20:48 +0300 Subject: arm64: cleanup {COMPAT_,}SET_PERSONALITY() macro There is some work that should be done after setting the personality. Currently it's done in the macro, which is not the best idea. In this patch new arch_setup_new_exec() routine is introduced, and all setup code is moved there, as suggested by Catalin: https://lkml.org/lkml/2017/8/4/494 Cc: Pratyush Anand Signed-off-by: Yury Norov [catalin.marinas@arm.com: comments changed or removed] Signed-off-by: Catalin Marinas --- arch/arm64/kernel/process.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'arch/arm64/kernel/process.c') diff --git a/arch/arm64/kernel/process.c b/arch/arm64/kernel/process.c index 85b953dd023a..e6bf19c1dddb 100644 --- a/arch/arm64/kernel/process.c +++ b/arch/arm64/kernel/process.c @@ -414,3 +414,11 @@ unsigned long arch_randomize_brk(struct mm_struct *mm) else return randomize_page(mm->brk, SZ_1G); } + +/* + * Called from setup_new_exec() after (COMPAT_)SET_PERSONALITY. + */ +void arch_setup_new_exec(void) +{ + current->mm->context.flags = is_compat_task() ?
