Subject: KVM: arm64: selftests: Consider all 7 possible levels of cache
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4138cc63d3efdd77de799aafb0bd183e1d655a0f;p=thirdparty%2Flinux.git

KVM: arm64: selftests: Consider all 7 possible levels of cache

In test_clidr() if an empty cache level is not found then the TEST_ASSERT
will not fire. Fix this by considering all 7 possible levels when iterating
through the hierarchy. Found by inspection.
