[OpenWrt-Devel] [PATCH 1/6] kernel: disable ARCH_WANTS_THP_SWAP by default

Sergey Ryazanov ryazanov.s.a at gmail.com
Mon May 21 05:12:32 EDT 2018 

Only one arch (x86_64) enables this option. So disable
ARCH_WANTS_THP_SWAP by default and remove referencies to it from all
configs (except x86_64) to make them clean.
