LoongArch: ptrace: Add function argument access API
Add regs_get_argument() which returns N th argument of the function call, This enables ftrace kprobe events to access kernel function arguments via $argN syntax for later use. E.g.: echo 'p bio_add_page arg1=$arg1' > kprobe_events bash: echo: write error: Invalid argument Signed-off-by: Qing Zhang <zhangqing@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
