Merge tag 'hardened-usercopy-v4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardened usercopy updates from Kees Cook: "This cleans up a minor Kconfig issue and adds a kernel boot option for disabling hardened usercopy for distro users that may have corner-case performance issues (e.g. high bandwidth small-packet UDP traffic). Summary: - drop unneeded Kconfig "select BUG" (Kamal Mostafa) - add "hardened_usercopy=off" rare performance needs (Chris von Recklinghausen)" * tag 'hardened-usercopy-v4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: usercopy: Allow boot cmdline disabling of hardening usercopy: Do not select BUG with HARDENED_USERCOPY
