/*
* 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.
