We can jump straight into the copy loop if the kernel is compiled for a
hardware that natively supports misaligned access. The user copy
bandwidth improvement on K3 and Ascaolon is shown as below:

Misaligned user copy, size: 512B (offset: [0:15] except 0, 8)
BW Improvement	| Write	| Read	|
K3		| 6.19%	| 3.43%	|
Ascalon		| 10.0%	| 11.4%	|

Aligned user copy, size: 512B (offset: 0, 8)
BW Improvement	| Write	| Read	|
K3		| 1.69%	| 0.90%	|
Ascalon		| 1.25%	| 3.32%	|
