From 593309423cbad0fab659a685834416cf12d8f581 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sat, 4 Apr 2020 01:33:05 +0200 Subject: x86/32: Remove CONFIG_DOUBLEFAULT Make the doublefault exception handler unconditional on 32-bit. Yes, it is important to be able to catch #DF exceptions instead of silent reboots. Yes, the code size increase is worth every byte. And one less CONFIG symbol is just the cherry on top. No functional changes.
