Michael Ellerman 36f8a2c4c6 [POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseries
Add a DEBUG config setting which turns on all (most) of the debugging
under platforms/pseries.

To have this take effect we need to remove all the #undef DEBUG's, in
various files. We leave the #undef DEBUG in platforms/pseries/lpar.c,
as this enables debugging printks from the low-level hash table routines,
and tends to make your system unusable. If you want those enabled you
still have to turn them on by hand.

Also some of the RAS code has a DEBUG block which causes a functional
change, so I've keyed this off a different (non-existant) debug #define.

This is only enabled if you have PPC_EARLY_DEBUG enabled also.

Linas Vepstas 093eda3ce5 [POWERPC] EEH: Fix PCI bridge handling bug
The EEH code needs to ignore PCI bridges; sort-of.  It was ignoring
them in the wrong place, and thus failing to set up the
PCI_DN(dn)->pcidev pointer.  Imprudent dereferencing of this pointer
would lead to a crash on cards with bridges.

Robert P. J. Day 5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

Linas Vepstas af52559218 [POWERPC] EEH: balance pcidev_get/put calls
This corrects a pci_dev get/put imbalance that can occur only in
highly unlikely situations (kmalloc failures, pci devices with
overlapping resource addresses).  No actual failures seen, this was
spotted during code review.

Linas Vepstas 5d5a0936b3 [PATCH] powerpc: Split out PCI address cache to its own file
25-pci-address-cache.patch

The core EEH file is rather large. This patch splits out a self-contained
chunk of it into its own file.  This is the chunk that performes the
caching and lookup of pci devices based on the i/o addresses of thier
resoures.  This code is almos architecture-independent and could be
used by any system that wanted to find a pci device based only on
the i/o address used by the device.
