Two weeks worth of fixes since rc1.
- I broke 16-byte alignment of the stack when we moved PPR into pt_regs.
Despite being required by the ABI this broke almost nothing, we eventually
hit it in code where GCC does arithmetic on the stack pointer assuming the
bottom 4 bits are clear. Fix it by padding the in-kernel pt_regs by 8 bytes.
- A couple of commits fixing minor bugs in the recent SLB rewrite.
- A build fix related to tracepoints in KVM in some configurations.
- Our old "IO workarounds" code written for Cell couldn't coexist in a kernel
that runs on Power9 with the Radix MMU, fix that.
- Remove the NPU DMA ops, these just printed a warning and should never have
been called.
- Suppress an overly chatty message triggered by CPU hotplug in some configs.
- Two small selftest fixes.
