From 00cf8baf9c2af3c17f9d77bb9d07d44d330d0df2 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 21 May 2020 22:05:27 +0200 Subject: [PATCH] x86/entry/64: Simplify idtentry_body All C functions which do not have an error code have been converted to the new IDTENTRY interface which does not expect an error code in the arguments. Spare the XORL.
