This reverts commit 7be5fe66cd024b9ffba7c52cdbf5effedeac2c0d. This commit broke resctrl, because it missed the fact that the virResctrlInfoGetCache() has side-effects causing it to actually change the virResctrlInfo parameter, not merely get data from it. This code will need some refactoring before we can try separating it from virCapabilities again. Signed-off-by: Daniel P.
