** Description changed: + [Impact] Change flush from congruence-first with dependencies to linear with no dependencies, which increases flush performance by 8x on P8, and 3x on P9 (as measured with null syscall loop, which will have the flush area in the L2). The flush also becomes simpler and more adaptable to different cache geometries. + + [Test Case] + TBD. + + [Regression Potential] + The risk is deemed low since the changes are confined to POWER only and the provided test kernels have been tested by IBM.
