3.16.56-rc1 review patch.  If anyone has any objections, please let me know.


From: Dan Williams <dan.j.willi...@intel.com>

commit edfbae53dab8348fca778531be9f4855d2ca0360 upstream.

Reflect the presence of get_user(), __get_user(), and 'syscall' protections
in sysfs. The expectation is that new and better tooling will allow the
kernel to grow more usages of array_index_nospec(), for now, only claim
mitigation for __user pointer de-references.
