From caf3cb2ef22e4b4ff9f6bb48f71ce30dae663326 Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Mon, 30 Mar 2026 07:57:44 +0200 Subject: [PATCH] x86/asm/segment: Use ASM_INPUT_RM in __loadsegment_fs() Use the ASM_INPUT_RM macro in __loadsegment_fs() to work around Clang problems with the "rm" asm constraint. Clang seems to always chose the memory input, while it is almost always the worst choice.
