03-eeh-addr-cache-cleanup.patch
This is a minor patch to clean up a buglet related to the PCI address cache.
(The buglet doesn't manifes itself unless there are also bugs elsewhere,
which is why its minor.). Also:
-- Improved debug printing.
-- Declare some private routines as static
-- Adds reference counting to struct pci_dn->pcidev structure

02-eeh-minor-cleanup.patch
This patch performs some minor cleanup of the eeh.c file, including:
-- trim some trailing whitespace
-- remove extraneous #includes
-- use the macro PCI_DN uniformly, instead of the void pointer chase.
-- typos in comments
-- improved debug printk's

01-pci-dn-uniformization.patch
This patch changes the rtas_pci interface to use the new struct pci_dn
structure for two routines that work with pci device nodes.
This patch also does some minor janitorial work: it uses some handy macros
and cleans up some trailing whitespace in the affected file.

and rename it to pci.c. This also required moving
arch/ppc64/kernel/pci.h into include/asm-powerpc (called
ppc-pci.h.

This patch pulls the PCI-related junk out of struct device_node and
puts it in a separate structure, struct pci_dn. The device_node now
just has a void * pointer in it, which points to a struct pci_dn for
nodes that represent PCI devices. It could potentially be used in
future for device-specific data for other sorts of devices, such as
virtual I/O devices.

Currently ppc64 has two mm_structs for the kernel, init_mm and also
ioremap_mm. The latter really isn't necessary: this patch abolishes it,
instead restricting vmallocs to the lower 1TB of the init_mm's range and
placing io mappings in the upper 1TB. This simplifies the code in a number
of places and eliminates an unecessary set of pagetables. It also tweaks
the unmap/free path a little, allowing us to remove the unmap_im_area() set
of page table walkers, replacing them with unmap_vm_area().

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
