Subject: [PATCH] ppc64: fix IPI on bpa_iic

This fixes a severe bug in the bpa_iic driver that caused
all sorts of problems.

We had been using incorrect priority values for inter processor
interrupts, which resulted in always doing CALL_FUNCTION
instead of RESCHEDULE or DEBUGGER_BREAK.

The symptoms cured by this patch include bad performance on
SMP systems spurious kernel panics in the IPI code.

Subject: [PATCH] ppc64: Fix oops for !CONFIG_NUMA

The SPARSEMEM EXTREME code (802f192e4a600f7ef84ca25c8b818c8830acef5a) that
went in yesterday broke PPC64 for !CONFIG_NUMA.

The problem is that (free|reserve)_bootmem don't take a page number as their
first argument, they take an address. Ruh roh.

Booted on P5 LPAR, iSeries and G5.

Subject: [PATCH] ppc64: iSeries early printk breakage

The earlier commit 8d9273918635f0301368c01b56c03a6f339e8d51
(Consolidate early console and PPCDBG code) broke iSeries because
it caused unregister_console(&udbg_console) to be called
unconditionally.  iSeries never registers the udbg_console.

This just reverts part of the change.

Subject: [PATCH] powerpc: Merge a few more include files

Merge a few asm-ppc and asm-ppc64 header files.
Note: the merge of setup.h intentionally does not carry
forward the m68k cruft.  That means this patch continues
to break the already broken amiga on the ppc32.

Subject: [PATCH] PPC64: large INITRD causes kernel not to boot

In PPC64 there are number of problems in arch/ppc64/boot/main.c that
prevent a kernel from making use of a large (greater than ~16MB) INITRD.
This is 64 bit architecture and really large INITRD images should be
possible.

Simply put the existing code has a fixed reservation (claim) address and
once the kernel plus initrd image are large enough to pass this address
all sorts of bad things occur. The fix is the dynamically establish the
first claim address above the loaded kernel plus initrd (plus some
"padding" and rounding). If PROG_START is defined this will be used as
the minimum safe address - currently known to be 0x01400000 for the
firmwares tested so far.

Subject: [PATCH] Separate pci bits out of struct device_node

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.

Subject: Allow PCI config space syscalls to be used by 64-bit processes.

The pciconfig_iobase, pciconfig_read and pciconfig_write system calls
were only implemented for 32-bit processes; for 64-bit processes they
returned an ENOSYS error.  This allows them to be used by 64-bit
processes as well.  The X server uses pciconfig_iobase at least, and
this change is necessary to allow a 64-bit X server to work on my G5.
