- * On the sun4/4c we need a place
- * to reliably map locked down kernel data.  This includes the
- * task_struct and kernel stack pages of each process plus the
- * scsi buffers during dvma IO transfers, also the floppy buffers
- * during pseudo dma which runs with traps off (no faults allowed).
- * Some quick calculations yield:
- *       NR_TASKS <512> * (3 * PAGE_SIZE) == 0x600000
- * Subtract this from 0xc00000 and you get 0x927C0 of vm left
- * over to map SCSI dvma + floppy pseudo-dma buffers.  So be
- * careful if you change NR_TASKS or else there won't be enough
- * room for it all.
