  powerpc/ptrace: replace ptrace_report_syscall() with a tracehook call (2018-12-10 15:19:58 +1100)

- ------------------------------------------------------------------
powerpc fixes for 4.20 #4

One notable fix for our change to split pt_regs between user/kernel, we forgot
to update BPF to use the user-visible type which was an ABI break for BPF
programs.

A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use
tracehook_report_syscall_entry() properly. We'll rework the code in next to
avoid the empty if body.

Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver.
The driver was finally able to be tested on the other hypervisor which exposed
several bugs. The fixes are all fairly minimal at least.

Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI
capable PHB, only seen on older hardware (MPC8378).

Fix our legacy serial code to look for "stdout-path" since the device trees were
updated to use that instead of "linux,stdout-path".

A change to the COFF zImage code to fix booting old powermacs.

A couple of minor build fixes.

Thanks to:
  Benjamin Herrenschmidt, Daniel Axtens, Dmitry V. Levin, Elvira Khabirova,
  Oliver O'Halloran, Paul Mackerras, Radu Rendec, Rob Herring, Sandipan Das.
