This is the first step in the direction of revisiting current practice of indiscriminate use of signed types for syscall arguments and memory addresses. * kernel_types.h (kernel_ureg_t): New type, typedef to unsigned long. * defs.h (struct tcb): Change type of u_arg from long to kernel_ureg_t. [HAVE_STRUCT_TCB_EXT_ARG]: Change type of ext_arg from long long to unsigned long long. * desc.c (decode_select): Change type of syscall arguments from long to kernel_ureg_t. (SYS_FUNC(oldselect)): Change type of select_args from long to kernel_ureg_t. * io.c (print_lld_from_low_high_val): Remove no longer needed cast of syscall arguments to unsigned long. * lseek.c (SYS_FUNC(lseek)): Cast syscall argument from unsigned long to long. * mem.c (print_mmap): Change type of syscall arguments from long to kernel_ureg_t. (SYS_FUNC(old_mmap), SYS_FUNC(old_mmap_pgoff)): Change type of u_arg from long to kernel_ureg_t. (SYS_FUNC(mmap), SYS_FUNC(mmap_pgoff), SYS_FUNC(mmap_pgoff)): Remove no longer needed cast of syscall arguments to unsigned long. * pathtrace.c (pathtrace_match): Change type of args and select_args from long to kernel_ureg_t. * util.c (getarg_ull): Remove no longer needed casts of syscall arguments to unsigned types.
