From bae54dc4f353653bbd3e3081754adad05da1d4dd Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 18 Jan 2019 00:05:40 +0100 Subject: x86/fpu: Get rid of CONFIG_AS_FXSAVEQ This was a "workaround" to probe for binutils which could generate FXSAVEQ, apparently gas with min version 2.16. In the meantime, minimal required gas version is 2.20 so all those workarounds for older binutils can be dropped.
