For my setup the problem is first seen after:
commit bdee237c0343 " x86: mm: Use 2GB memory block size on large memory x86-64 systems"
which appeared in v3.19 and forced a 2GB memory block size. But it could happen on older systems depending on the block size picked based on the alignment of max_pfn.
Looking further back (to v3.15) ... we used a fixed MIN_MEMORY_BLOCK_SIZE for all systems prior to
commit 982792c782ef "x86, mm: probe memory block size for generic x86 64bit"
So maybe:
Cc: stable@kernel.org #v3.15
