So, ignore the first hunk above, that was my typo.  

Here is the chunk of the series file I have:

idr-rename-max_level-to-max_idr_level.patch
idr-rename-max_level-to-max_idr_level-fix.patch
idr-rename-max_level-to-max_idr_level-fix-fix-2.patch
#NEXT_PATCHES_END
#
linux-next.patch
i-need-old-gcc.patch
idr-rename-max_level-to-max_idr_level-fix-3.patch
arch-alpha-kernel-systblss-remove-debug-check.patch
#
#NEXT_PATCHES_START linux-next-urgent

So idr-rename-max_level-to-max_idr_level-fix-3.patch is excluded form
linux-next :-( I guess I need to just move that further down in the
series file?  Though when you send the preceding three patches to Linus,
that fix-3 patch will be needed when I merge the thermal tree.
