Subject: [PATCH] powerpc/sstep: Let compute tests specify a required cpu
feature
References: jsc#SLE-13847
Patch-mainline: v5.9-rc1
Git-commit: 301ebf7d69f6709575d137a41a0291f69f343aed
An a array of struct compute_test's are used to declare tests for
compute instructions. Add a cpu_feature field to struct compute_test as
an optional way to specify a cpu feature that must be present. If not
present then skip the test.
