enable_kernel_vsx() was commented since anything was using
it. It changes with vmx_crypto driver that call VSX instructions
and need kernel_vsx enabled in order to do it properly. Without
a way to enable VSX instruction vmx_crypto fails into an exception.
These patches uncomment enable_kernel_vsx() rountine and put it
available for use. Also adds it in vmx_crypto in order to
enable kernel_vsx before use VSX instructions.
Leonidas S. Barbosa (2):
Uncomment and make enable_kernel_vsx() routine available
Adding enable_kernel_vsx() to access VSX instructions
