From b40fa75e1542e069a4eb9b33d62061d4ae734537 Mon Sep 17 00:00:00 2001 From: Jinyang He Date: Sat, 29 Oct 2022 16:29:31 +0800 Subject: LoongArch: Remove unused kernel stack padding The current LoongArch kernel stack is padded as if obeying the MIPS o32 calling convention (32 bytes), signifying the port's MIPS lineage but no longer making sense. Remove the padding for clarity.
