Merge tag 'openrisc-for-linus' of git://github.com/openrisc/linux
Pull OpenRISC fixes from Stafford Horne: "OpenRISC fixes for build issues that were exposed by kbuild robots after 4.11 merge. All from allmodconfig builds. This includes: - bug in the handling of 8-byte get_user() calls - module build failure due to multile missing symbol exports" * tag 'openrisc-for-linus' of git://github.com/openrisc/linux: openrisc: Export symbols needed by modules openrisc: fix issue handling 8 byte get_user calls openrisc: xchg: fix `computed is not used` warning
