From 2a8986fc5e1cb686dd3aae3022459aea23b9823a Mon Sep 17 00:00:00 2001 From: Leonardo Bras Date: Wed, 3 Jan 2024 13:00:23 -0300 Subject: riscv: Introduce set_compat_task() in asm/compat.h In order to have all task compat bit access directly in compat.h, introduce set_compat_task() to set/reset those when needed. Also, since it's only used on an if/else scenario, simplify the macro using it.
