From 1218874186381748485305f187647c15570139a4 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 1 Aug 2023 16:07:11 +0200 Subject: x86/init: Initialize signal frame size late commit 54d9a91a3d6713d1332e93be13b4eaf0fa54349d upstream No point in doing this during really early boot. Move it to an early initcall so that it is set up before possible user mode helpers are started during device initialization.
