WARNING: unmet direct dependencies detected for ARCH_WANTS_THP_SWAP
Depends on [n]: TRANSPARENT_HUGEPAGE [=n]
Selected by [y]:
- X86 [=y] && X86_64 [=y]
The ARCH_WANT* symbols are selected by the arch to communicate
requests to THP if enabled. Those mustn't be inside the 'if THP' block
for user-visible THP options of course. Move them back out.
