Hmm, this looks like fallout from the conversion to the generic VDSO
infrastructure. This patch resolves it:

That one's triggered by a change in the ordering of some include
directives in the drivers/staging/octeon code, and fixed by commit
0228ecf6128c ("MIPS: octeon: Include required header; fix octeon
ethernet build") in mips-next.
