Hi,

Linux version : 2.4.14
File with a supposed probleme : linux/drivers/char/agp/agpgart_be.c

I have a powerpc with an ati128 AGP.

When i compile the kernel i have this error : error "Please define
flush_cache."

this error come from the function flush_cache in agpgart_be.c where
definition for powerpc are not setting . Why ?
