This comes from 09b09ab71840 ("mm, x86/mm: Make the batched unmap TLB flush
API more generic"), backported from e73ad5ff2f76d upstream.

My 10-second analysis suggests that we should backport
dcc2dc45f7cf ("sched/headers, mm: Move 'struct tlbflush_unmap_batch' from
<linux/sched.h> to <linux/mm_types_task.h>")
