zap_pid_ns_processes: clear TIF_NOTIFY_SIGNAL along with TIF_SIGPENDING
I can not explain it, but this patch causes all my parisc64 (C3700)
boot tests to crash. There are lots of memory corruption BUGs such as

[ 0.474956] Kernel panic - not syncing: Attempted to kill the idle task!
SeaBIOS wants SYSTEM RESET.
This is with qemu v9.0.1.
Just to be sure, did you tested the same kernel on physical hardware as well?
No, I don't have hardware. I only have qemu. That is why I copied you and
the parisc mailing list.
Yes, sorry, I saw your top line in the mail after I already sent my reply....
I would hope that someone can either confirm that
this is a real problem or that it is qemu related. If it is qemu related,
I'll just stop testing c3700 64-bit support with qemu on v6.1.y and other
branches if/when the problem shows up there as well.
I just booted 6.1.95 successfully in qemu and on my physical C3700 machine.
I assume the problem can be reproduced with your .config ?
Please send it to me off-list, then I can try again.
Done.
Thanks,
Guenter
