p10_aes_gcm_crypt() is abusing the scatter_walk API to get the virtual address for the first source scatterlist element. But this code is only built for PPC64 which is a !HIGHMEM platform, and it can read past a page boundary from the address returned by scatterwalk_map() which means it already assumes the address is from the kernel's direct map. Thus, just use sg_virt() instead to get the same result in a simpler way.
