* Sandipan Das:
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.
Ugh. Do you have a reference for that?
We need to fix this in glibc.
Thanks, Florian
