Didn't I fix this with
mm-early_ioremap-add-prototype-for-early_memremap_pgprot_adjust-fix.patch?
This fix is lame - x86's fixmap.h should be standalone. But this gets us
moving ahead with the MM changes for now.

I think you did fix it but I was surprised by the level
of fallout from this patch and then there were objections
to adding header dependencies unnecessarily such as this
https://lore.kernel.org/lkml/YK3vrIB7cWop+UIW@gmail.com/ . That was
specific to modifying the x86 headers so your fix should not hit the same
objection but still, as you said, x86 fixmap should be standalone.
