Since v3 the NMI fixmap entries and locks have moved into their own
structure. This moves the indirection up from the 'lock', which should
be more acceptable to polite society.
Changes are noted in each patch.

This touches a few trees, so I'm not sure how best it should be merged.
Patches 11 and 12 are reducing a race that is made worse by patch 4, I'd
like them to arrive together, even though patch 11 doesn't depend on anything
else in the series. A partial merge of this would  be 1-3 and 11.

Patch 11 makes the reschedule to memory_failure() run as soon as possible.
