Subject: arm64: export __cpu_{clear,copy}_user_page functions
X-Git-Tag: v4.14-rc1~7179^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bec7cedc8a92bfe96d32febe72634b30c63896bd;p=platform%2Fkernel%2Flinux-rpi.git

arm64: export __cpu_{clear,copy}_user_page functions

The __cpu_clear_user_page() and __cpu_copy_user_page() functions
are not currently exported. This prevents modules from using
clear_user_page() and copy_user_page().
