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
