8545cd2011 [POWERPC] Remove unused inclusion of linux/ide.h
Remove unneeded inclusion of linux/ide.h
It does not compile with CONFIG_BLOCK=n.

Remove asm/ide.h from ksyms file, it gets included earlier via
linux/ide.h.

Compile tested with all defconfig files.

5873c9bdb0 [POWERPC] Make pci_read_irq_line the default on mpc7448hpc2 board
The following patch adds a tsi108/9 pci interrupt controller host.
On mpc7448hpc2 board, pci_irq_fixup function is removed, which makes the
pci_read_irq_line be the default pci irq fixup.

f90bb153b1 [POWERPC] Make pci_read_irq_line the default
This patch reworks the way IRQs are fixed up on PCI for arch powerpc.

It makes pci_read_irq_line() called by default in the PCI code for
devices that are probed, and add an optional per-device fixup in
ppc_md for platforms that really need to correct what they obtain
from pci_read_irq_line().

It also removes ppc_md.irq_bus_setup which was only used by pSeries
and should not be needed anymore.

I've also removed the pSeries s7a workaround as it can't work with
the current interrupt code anyway. I'm trying to get one of these
machines working so I can test a proper fix for that problem.

I also haven't updated the old-style fixup code from 85xx_cds.c
because it's actually buggy :) It assigns pci_dev->irq hard coded
numbers which is no good with the new IRQ mapping code. It should
at least use irq_create_mapping(NULL, hard_coded_number); and possibly
also set_irq_type() to set them as level low.

7233593b78 [POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2
This adds a new hardware information table for mpic. This enables
the mpic code to deal with mpic controllers with different register
layouts and hardware behaviours.

This introduces CONFIG_MPIC_WEIRD.  For boards with non standard mpic
controllers, select CONFIG_MPIC_WEIRD and add its hardware information
in the mpic_infos[] array.

TSI108/109 PIC takes the first index of weird hardware information
table.  :)  The table can be extended. The Tsi108/109 PIC looks like
standard OpenPIC but, in fact, is different in register mapping and
behavior.

The patch does not affect the behavior of standard mpic.  If
CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to
the current code.

[benh@kernel.crashing.org:
This patch is a slightly cleaned up version of Zang Roy's support for
the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new
version of the type macros and changes the way MPIC is selected in
Kconfig to better match what is done for other system devices.

8efca49329 [POWERPC] mpc: Constify & voidify get_property()
Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.
