63 - Enable this if you want the use virtually-mapped kernel stacks
94 - Allocated stacks are cached and later reused by new threads, so memcg
95 accounting is performed manually on assigning/releasing stacks to tasks.
100 - On arm64, all VMAP's stacks need to have the same alignment to ensure
103 - This does not address interrupt stacks - according to the original patch
