Create new public function to create cpupools, can take as parameter the scheduler id or a negative value that means the default Xen scheduler will be used. Signed-off-by: Luca Fancellu <luca.fancellu@arm.com> --- Changes in v3: - Fixed comment (Andrew) Changes in v2: - cpupool_create_pool doesn't check anymore for pool id uniqueness before calling cpupool_create.
