2. Fix to remove the "Unknown IPI message 0x1" message when
    secondary CPU boots.

For this one you are avoiding a wakeup IPI and rather
relying on schedule IPI. That just avoiding the issue.

This doesn't seems to be right. Refer below thread.

Russell,
When do you plan to fix the SGI usage as discussed
in above thread. I thought SGI1 usage was ok for OMAP,
realview/versatile and MSM.
