  usercopy: Add tests for all get_user() sizes (2017-02-21 11:59:38 -0800)

----------------------------------------------------------------
This improves the usercopy tests:
- check zeroing on failed copy_from_user()/get_user() (caught bug on ARM)
- adjust tests for SMAP/PAN (can't zero userspace memory on failure)

----------------------------------------------------------------
Hoeun Ryu (1):
      usercopy: add testcases to check zeroing on failure

Kees Cook (2):
      usercopy: Adjust tests to deal with SMAP/PAN
      usercopy: Add tests for all get_user() sizes
