Peilin Ye 8b4f08f280 ptrace: Prevent kernel-infoleak in ptrace_get_syscall_info() ... commit 0032ce0f85 upstream. ptrace_get_syscall_info() is potentially copying uninitialized stack memory to userspace, since the compiler may leave a 3-byte hole near the beginning of `info`. Fix it by adding a padding field to `struct ptrace_syscall_info`.
