[4.1-stable] missing arm commit, "fa0708b"

Hello,

I found that the commit, "fa0708b ARM: 8471/1: need to save/restore arm
register(r11) when it is corrupted" is missed from 4.1-stable tree until
4.1.28. Without it, cpu_pm_enter() with specific test environment causes
hang-up on arm.

Any plan to apply the commit to 4.1-stable?

Best Regards,
- Seung-Woo Kim
