1. Add the trivial sizeof_long() helper and change other callers of is_ia32_task() to use it. TODO: is_ia32_task() is not what we actually want, TS_COMPAT does not necessarily mean 32bit. Fortunately syscall-like insns can't be probed so it actually works, but it would be better to rename and use is_ia32_frame(). 2. As Jim pointed out "ncopied" in arch_uretprobe_hijack_return_addr() and adjust_ret_addr() should be named "nleft". And in fact only the last copy_to_user() in arch_uretprobe_hijack_return_addr() actually needs to inspect the non-zero error code. TODO: adjust_ret_addr() should die. We can always calculate the value we need to write into *regs->sp, just UPROBE_FIX_CALL should record insn->length.
