New Revision: 322109
URL: https://svnweb.freebsd.org/changeset/base/322109

Log:
  Mark each cpu in the appropriate cpuset_domain set. This allows devices to
  handle cases where they can only run on a single domain.
  
  To allow all devices access to this set we need to move reading the domain
  earlier in the boot as it was previously handled in the CPU driver, however
  this is too late for the GICv3 ITS driver.
