This risks breaking # userspace, though we believe it is unused in practice. # # - A bug fix for, and then the removal of, our custom stack expansion # checking. We now allow stack expansion up to the rlimit, like other # architectures. # # - Remove the remnants of our (previously disabled) topology update # code, which tried to react to NUMA layout changes on virtualised # systems, but was prone to crashes and other problems. # # - Add PMU support for Power10 CPUs. # # - A change to our signal trampoline so that we don't unbalance the link # stack (branch return predictor) in the signal delivery path. # # - Lots of other cleanups, refactorings, smaller features and so on as # usual. # # Thanks to: Abhishek Goel, Alastair D'Silva, Alexander A.
