From 45fc24e89b7cc2e227b2f03d99dda0a2204bf383 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Thu, 23 Jan 2020 10:41:20 -0800 Subject: x86/mpx: remove MPX from arch/x86 From: Dave Hansen MPX is being removed from the kernel due to a lack of support in the toolchain going forward (gcc). This removes all the remaining (dead at this point) MPX handling code remaining in the tree. The only remaining code is the XSAVE support for MPX state which is currently needd for KVM to handle VMs which might use MPX.
