Clip solid fills

So I am working on the assumption that the residual hangs I am seeing after enabling/disable the GMCH to force the GTT flush are real batch buffer bugs...

For instance http://bugs.freedesktop.org/attachment.cgi?id=34417 looks like we attempt to write well beyond the end of the buffer. In which case the attached should workaround the issue.
