From 1201937491822b61641c1878ebcd16a93aed4540 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 18 Jun 2019 19:10:54 +0100 Subject: arm64: Expose ARMv8.5 CondM capability to userspace ARMv8.5 adds new instructions XAFLAG and AXFLAG to translate the representation of the results of floating point comparisons between the native ARM format and an alternative format used by some software. Add a hwcap allowing userspace to determine if they are present, since we referred to earlier CondM extensions as FLAGM call these extensions FLAGM2.
