8c1449a84d
This patch changes the kernels generated by OpenMP to have protected visibility. This is unlikely to change anything functionally. However, protected visibility better matches the behaviour of these GPU kernels. We do not expect any pending shared library load to preempt these kernels so we can specify a more restrictive visibility.
