From 14d61d4e577c57ba77b826c6cc9d99a0b3f3fc37 Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Mon, 4 Dec 2017 16:33:26 +0100 Subject: [PATCH] efi_stub: Fix GDT_NOTSYS check The get_codeseg32() wants to know if a passed in descriptor has flag GDT_NOTSYS set (desc & GDT_NOTSYS), not whether desc and GDT_NOTSYS are not != 0 (desk && GDT_NOTSYS). This is an obvious typo. Fix it up.
