Here are three more sparse-triggered fixes which didn't fit anywhere
else.  The first one gets rid of some quoting in palinfo.c which
sparse doesn't like.  This used to be necessary because GCC would
otherwise warn about an unknown trigraph.  That's not a problem
anymore since the kernel is now being compiled with -Wno-trigraphs.
The efirtc.c patch is mostly sparse-annotations but also cleans up
trailing whitespace.  Finally, the bitfields in rwlock_t are changed
to be explicitly "unsigned" to avoid a warning from sparse (it doesn't
like 1-bit signed bitfields in particular).
