[GIT PULL] Openrisc fixes for 4.11

[Stafford Horne]

Hi Linus

Please consider for pull,

OpenRISC fixes for build issues that were exposed by kbuild robots after
4.11 merge. All from allmodconfig builds. This includes:
 - bug handling 8 byte get_user calls
 - module build failure due to multile missing symbol exports

Also, FYI, there is a build warning due to statx syscall missing in
asm-generic/unistd.h.  I have patch for that waiting for ok from arm64 guys
who also use asm-generic:

  https://lkml.org/lkml/2017/3/13/657

I figure that will go in through another queue, if not, I can pick it up.

The following changes since commit 4495c08e84729385774601b5146d51d9e5849f81:
