Add support for ppc64le hwcaps tunables Resolves: RHEL-1017
2023-09-13 20:33:45 +00:00
From 60b4dd25790342b40e8942e3a4115f511a6b6911 Mon Sep 17 00:00:00 2001

Subject: powerpc64: Add checks for Altivec and VSX in ifunc selection
We'd like to support processors without Altivec or VSX, so check
the relevant hwcap bits before selecting them.
