Hi folks !

Maybe anybody will enlighten me, is the difference between
IRQ maps initialization (arch/ppc/kernel/prep_pci.c) in 2.4
and 2.2 intentional or not? The difference is in that for

Mesquite_pci_IRQ_map,
Sitka_pci_IRQ_map,
MTX_pci_IRQ_map,
MTXplus_pci_IRQ_map and
Genesis2_pci_IRQ_map

some fields have been initialised for 2.2.16 and zero for 2.4.

Look at all of prep_pci.c and you'll see that many board specific
PCI changes were made in the linuxppc_2_2 tree that have not
yet been merged up to linuxppc_2_3.  It is in the plan, however.

The map changes are benign cruft from a set of changes I merged
in a long time ago.  It was a hack to place 0x1e value at the
PIB's IDSEL for some IDE fixups that aren't really necessary.

Now you know the whole story. :)
