For me, reverting commit 33def8498fdde180023444b08e12b72a9efed41d 
("treewide: Convert macro and uses of __section(foo) to 
__section("foo")") fixed this compile error and one other introduced by 
the same patch.
Unfortunately I wasn't able to come up with a fix for that, but I have 
CC the author of that patch.

Thanks!
