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 <panand@redhat.com> Signed-off-by: Yury Norov <ynorov@caviumnetworks.com> [catalin.marinas@arm.com: comments changed or removed] Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
