Marius Strobl b08a33129a - Turn off interrupts instead of only entering a critical section
while doing the block store workaround so we restore the correct
  floating-point registers state in case of nested floating-point
  operations resulting from nested interrupts. This allows the
  VIS-based block copy/zero functions to be used on machines
  requiring this workaround. Alternatively, we could take care of
  saving the floating-point registers here, which would be more
  inefficiently though and also involves turning off interrupts.
- It turns out that the SCZ_PCI_DMA_SYNC register doesn't work
  like the TOMXMS_PCI_DMA_SYNC_PEND one (but more like the
  corresponding register in of Hummingbird and Sabre bridges)
  and writing the INO of the respective device to it causes a
  Safari bus error. However, due to the Schizo errata I-23,
  SCZ_PCI_DMA_SYNC can't be used as intended either, so remove
  consistent DMA syncing for Schzio bridges for now, which means
  that add-on cards with non-"sun4u compliant" (whatever that
  means exactly) PCI-PCI-bridges should be avoided until the
  proper workaround is implemented. [1]
