=2E.. in the mainline since 3.13.  What has changed in -next?

We could put ifndef CONFIG_MMU around that declaration, I guess...

PS: Pity that we can't really use -std=3Dgnu99 - use of compound litera=
ls
in initializers is too widespread ;-/  The last time I tried to do some=
thing
about that, I gave up when I got to __pgprot() users; in principle, we
could switch pgprot_t to a bitwise type and let sparse take care of the
typechecking, but it was too much work to pull off.  Might be worth
trying again someday...
