Florian Weimer e627106266 POWER: Add context-synchronizing instructions to pkey_write [BZ #25954] 
Sandipan Das reported that,

"The Power ISA mandates that all writes to the Authority
Mask Register (AMR) must always be preceded as well as
succeeded by a context-synchronizing instruction. This
applies to both the privileged and unprivileged variants
of the Move To AMR instruction.

This [requirement] is from Table 6 of Chapter 11 in page 1134 of Power
ISA 3.0B. The document can be found here:
<https://ibm.ent.box.com/s/1hzcwkwf8rbju5h9iyf44wm94amnlcrv>
"
