Merge tag 'modules-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules updates from Jessica Yu: - Some modules-related kallsyms cleanups and a kallsyms fix for ARM. - Include keys from the secondary keyring in module signature verification. * tag 'modules-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: ARM: module: Fix function kallsyms on Thumb-2 module: Overwrite st_size instead of st_info module: make it clearer when we're handling kallsyms symbols vs exported symbols modsign: use all trusted keys to verify module signature
