Subject: [PATCH] MIPS: Fix build failure on mips_sc_is_activated()

The commit ea31a6b20371 ("MIPS: Honor L2 bypass bit") breaks
malta build as follows. Looks like not compile-tested :(

Already fixed in the linux-mips git tree by an identical patch in
commit 9a3475880131752d3d78ac25516fd3eab3fca871.

Thanks anyway!

This isn't in Linus's tree yet; please ask him to pull it in time for
