From 2a598d0b2800aa23ba51adcf060cec524aaa63b2 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 4 Aug 2023 17:24:34 +0800 Subject: crypto: lib - Move mpi into lib/crypto As lib/mpi is mostly used by crypto code, move it under lib/crypto so that patches touching it get directed to the right mailing list.
