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?
Please note, that 64-bit hppa (C3700) support in qemu was just recently added
and is still considered experimental.
So, maybe it's not a bug in the source, but in qemu...?!?
