This break on x86, HIGHMEM=n:

arch/x86/mm/iomap_32.c: In function ‘kmap_atomic_prot_pfn’:
arch/x86/mm/iomap_32.c:64: error: implicit declaration of function
‘kmap_atomic_idx_push’
arch/x86/mm/iomap_32.c: In function ‘iounmap_atomic’:
arch/x86/mm/iomap_32.c:101: error: implicit declaration of function
‘kmap_atomic_idx_pop’

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