to its currently enabled warnings. For the lack of a better place, most
global function prototype wound up in <machine/autoconf.h> unless there
was a better place for them. ofb_* structs renamed to offb_* to avoid
conflict with ofb_softc in <dev/ofw/openfirm.h>
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.
XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));
by someone!
