by Slava Semushin <slava.semushin@gmail.com>. To verify that no nasty side effects of duplicate includes (or their removal) have an effect here, I've compiled an i386/ALL kernel with and without the patch, and the only difference in the resulting .o files was in shifted line numbers in some assert() calls. The comparison of the .o files was based on the output of "objdump -D". Thanks to martin@ for the input on testing.
