[stable-4.9 && 4.14 0/2] CVE 2018-1000026 fixes

Hi Greg,

This is clean cherry-pick from upstream 4.16 for CVE 2018-1000026

Other OS vendors have the fixes in their kernels[1][2], but not yet in upstream stable tree for 4.9 and 4.14.

Compile tested with 4.14.93.

Please consider to include them.

Thanks, Jack Wang
