Subject[GIT PULL] hardened-usercopy updates for v4.19-rc1
Hi Linus,

Please pull these hardened-usercopy changes for v4.19-rc1. 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).

Thanks!

-Kees
