    Same with set_phy_reg, ohci_soft_reset, ohci_hw_csr_reg. At least the
    callers of ohci_hw_csr_reg (in particular, csr_highlevel.host_reset,
    furthermore csr_highlevel.add_host) could fairly easily be converted to
    a workqueue job or perhaps moved to the nodemgr thread. I have not
    checked the other offending functions yet.
