This break on x86, HIGHMEM=n:

arch/x86/mm/iomap_32.c: In function â??kmap_atomic_prot_pfnâ??:
arch/x86/mm/iomap_32.c:64: error: implicit declaration of function
â??kmap_atomic_idx_pushâ??
arch/x86/mm/iomap_32.c: In function â??iounmap_atomicâ??:
arch/x86/mm/iomap_32.c:101: error: implicit declaration of function
â??kmap_atomic_idx_popâ??

The use of the kmap idx there looks a little delicate so I'm not sure how
to fix this.
