Hi all,
After merging the tip tree, today's linux-next build (native perf)
failed like this:
In file included from util/intel-pt-decoder/../../../arch/x86/lib/insn.c:16,

and many similar ...
Caused by commit
a1be25a30cf6 ("x86/insn: Use get_unaligned() instead of memcpy()")
"native" here is ppc64le. gcc (Debian 10.3.0-11) 10.3.0
I have used the tip tree from next-20211005 for today.
