// A more generic option would be 'regs_get_kernel_argument' but kernels have a very sparring support of it
// Use the following macro for now
#define GET_KERNEL_ARGUMENT0(regs) regs->di
#define GET_KERNEL_ARGUMENT1(regs) regs->si
#define GET_KERNEL_ARGUMENT2(regs) regs->dx
#define GET_KERNEL_ARGUMENT3(regs) regs->cx
