Description Harald Reindl 2018-03-26 17:57:40 UTC 
##############################################################################
# # Enable lock elision support for these architectures
#
# At the moment lock elision is disabled on x86_64 until there's a CPU that
# would actually benefit from enabling it.  Intel released a microcode update
# to disable HLE and RTM at boot and the Fedora kernel now applies it early
# enough that keeping lock elision enabled should be harmless, but we have
# disabled it anyway as a conservative measure.
#
# We have not yet tested enabling ppc64 or ppc64le lock elision.
#
# We have disabled elision on s390/s390 because of bug 1499260.

from when is that comment?

we have now Broadwell/Skylarke SP  and so there is a CPU that would benefit
Comment 1 Florian Weimer 2018-03-26 17:59:45 UTC 
This has been fixed in Fedora 28.  We are not going to backport this to previous Fedora releases.
