Right, indeed the words here got swapped. They look very similar and also a cross compile would not even detect the problem because the non-existent config option would simply evaluate to 0.

Commit 66f24fa766e3 ("mm: drop redundant ARCH_ENABLE_SPLIT_PMD_PTLOCK") selects the non-existing config ARCH_ENABLE_PMD_SPLIT_PTLOCK in ./arch/powerpc/platforms/Kconfig.cputype, but clearly it intends to select ARCH_ENABLE_SPLIT_PMD_PTLOCK here (notice the word swapping!), as this commit does select that for all other architectures. Rectify selection to ARCH_ENABLE_SPLIT_PMD_PTLOCK instead.
