From c6dbd3e5e69cf3ca47a3864115d4cbdd44619243 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 15 Nov 2021 17:46:39 +0100 Subject: x86/mmx_32: Remove X86_USE_3DNOW This code puts an exception table entry on the PREFETCH instruction to overwrite it with a JMP.d8 when it triggers an exception. Except of course, our code is no longer writable, also SMP. Instead of fixing this broken mess, simply take it out.
