This does not build at all for me.

I get

    ./arch/x86/include/asm/current.h:49:9: error: call to undeclared
function '__typeof_unqual__'; ISO C99 and later do not support
implicit function declarations [-Wimplicit-function-declaration]

when running the Rust 'bindgen', and what seems to be going on is that
my version of *gcc* does support __typeof_unqual__, so I end up with

    CONFIG_CC_HAS_TYPEOF_UNQUAL=y

in my kernel config, but I think that 'bindgen' that generates the
Rust bindings is based on LLVM, and clearly does not understand
__typeof_unqual__.

I have bindgen 0.69.5 (plain F40 install), in case somebody wants to test.

Apparently few people test linux-next with Rust enabled, and the
reports that I find on lkml were ignored.

I do see reports of this failure on lkml from mid-December, so it's
not like I'm the first person ever to see this.

Anyway, pulled and then unpulled again.
