# Commit 41c7700a00011ad08be3c9d71126b67e08e58ac3 # Date 2019-08-29 15:10:07 +0200 # Author Jan Beulich <jbeulich@suse.com> # Committer Jan Beulich <jbeulich@suse.com> x86: properly gate clearing of PKU feature setup_clear_cpu_cap() is __init and hence may not be called post-boot. Note that opt_pku nevertheless is not getting __initdata added - see e.g. commit 43fa95ae6a ("mm: make opt_bootscrub non-init").
