Yep, will do, not sure which commit to attribute to Fixes though. Probably:

41e94a851304 add devm_memremap_pages

As it seems to be the first one that might cause high_memory to overlap
with VMALLOC.

And will update that too. The patch is over a year old, and at the time of
submission the generic implementation used is_vmalloc_addr.
