Kernel function ppxxccooppyy() can be invoked in one of two forms.

The first form copies _n_u_m__b_y_t_e_s  from physical address _s_r_c into kernel data
virtual address  _d_e_s_t. This  form is selected  by setting argument  _f_l_a_g to
manifest constant SSEEGG_338866_KKDD.

The second  form copies _n_u_m__b_y_t_e_s from system global  address _s_r_c to kernel
data virtual  address _d_e_s_t. This form is selected  by setting argument _f_l_a_g
to manifest constant SSEEGG_338866_KKDD|SSEEGG_VVIIRRTT.

No alignment restrictions are placed on _s_r_c or _d_e_s_t.
