[PATCH] RTEMS: Increase MSIZE from 128 to 256

[Joel Sherrill]

My original version of this change wrapped it in an RTEMS new stack macro.

I am not sure about this change going into 4.11. If the new stack went
in as well that is a different story.

Because of the long time frame between 4.10 and 4.11 (yes some people
have got married and had children), users are having to using 4.11.

Can this sit out of the changes until 4.11 and then go in ?
