Jiang Liu 0f406f5071 zram: optimize memory operations with clear_page()/copy_page() ... (cherry pick from commit 42e99bd975) Some architectures provides architecture-specific, optimized version of clear_page()/copy_page(), which may have better performance than memset()/memcpy(). So use clear_page()/copy_page() to optimize zram performance if possible.
