The patch itself looks reasonable, but are you able to test it on
anything more than the s390*?  Once its been on mainline for a while
without problems, it looks to be safe enough for the branches, but
I was wondering if we could at least test it on a primary platform
or two, before committing to mainline.  I appreciate that the change
should only affect code that currently fails, but reload patches
make me nervous, especially during stage3.

I'll preapprove this patch for mainline, once its had a little more
testing.

Thanks for fixing this.

Roger
