This patch is a resend from LKML since it has yet to be applied in 
either bk7. Patrick suggested I send it here. This patch fixes 
compilation failures in ppa.c and imm.c that were introduced in 2.5.70-bk1.

* Removes the 'int hostno' parameter from imm_proc_info().
Parameter isn't used and breaks the pointer matching for Scsi_Host.
* Added the prototype for imm_proc_info() in imm.h
* Modified line 280 of ppa.c to match concept on line 263 of imm.c.
