I would welcome a powerpcspe porter to join the kernel team, but until
that happens you should not expect any fixes from our side. (If you
had a porterbox available, this might be a more reasonable request.)
The breaking commit appears to be:
commit 3cdfcbfd32b9d1c0d4a6fa80ee9c390927aab948
Author: Paul Mackerras <paulus@ozlabs.org>
Date: Wed Aug 30 14:12:25 2017 +1000
powerpc: Change analyse_instr so it doesn't modify *regs
The other reference to ptesync in this file is guarded by
"#ifdef __powerpc64__", so most likely that's needed around the new
use. But I don't know whether a fix is as simple as that.
The upstream address to contact is linuxppc-dev@lists.ozlabs.org.
