selftests/powerpc: Adjust wild_bctr to build with old binutils (2018-11-15 23:05:17 +1100)
- ------------------------------------------------------------------ powerpc fixes for 4.20 #3
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.
Thanks to: Alistair Popple, Gustavo Romero, Nicholas Piggin, Satheesh Rajendran, Scott Wood.
