Adding davem for the sparc issue, Martin for the s390 one.

Martin - can we just remove the
select HAVE_GCC_PLUGINS
from the s390 Kconfig file (or perhaps add "if BROKEN" or something to
disable it).
Because if it's not getting fixed, it shouldn't be exposed.

Hmm. I assume it's
arch/sparc/include/asm/cacheflush_32.h
that wants a forward-declaration of 'struct page', and doesn't include
any header files.
The fix is presumably to move the
#include <asm/cacheflush.h>
in drivers/staging/media/omap4iss/iss_video.c down to below the
<linux/*> includes?
The old patchwork link you had for a fix no longer works, I think
because the patchwork database got re-generated during the upgrade
(and the patchwork numbering isn't stable).
Davem?
