Will Deacon 42309ab450 ARM: 8087/1: ptrace: reload syscall number after secure_computing() check ... On the syscall tracing path, we call out to secure_computing() to allow seccomp to check the syscall number being attempted. As part of this, a SIGTRAP may be sent to the tracer and the syscall could be re-written by a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall is ignored by the current code unless TIF_SYSCALL_TRACE is also set on the current thread. This patch slightly reworks the enter path of the syscall tracing code so that we always reload the syscall number from current_thread_info()->syscall after the potential ptrace traps.
