IDE Partition check overwrites vectors

[Jim Potter]

I'm implementing the IDE driver on my embedded system, and I've got a
strange problem -- when it performs the Partition check, it overwrites
the vector area (when in read_cache_page()).  Obviously, some caching
variable hasn't been setup, so it's writing to addr zero;  I'm not a mm
person, anyone have any suggestions on this?  Many thanks.

The system is Linux version 2.4.21-rc6, pulled from linuxppc_2_4_devel
several days ago, with a custom platform entry adapted from ev64260.c.
