[PATCH v2 0/2] ARM: ptrace: Restore syscall skipping and restart while tracing

[Kees Cook]

Hi,

Fix tracing on arm since commit 4e57a4ddf6b0 ("ARM: 9107/1: syscall:
always store thread_info->abi_syscall"). This was seen with the broken
seccomp tests "syscall_errno", "syscall_faked", and "syscall_restart".

Thanks!

v2:
- split fixes
- move scno store into the actual restart path
v1: https://lore.kernel.org/lkml/20230804071045.never.134-kees@kernel.org
