Hi Linus !
Here's your batch of powerpc stuff for 2.6.34. As you can see, it's
reasonably small this time around. There's a pile of scalability
improvements from Anton, a batch of raw_spinlock conversion from Thomas,
and a few more bits and pieces.
Cheers,
Ben.

Hi,
I should apologize ahead of time for my lack of knowledge with PCI.
I'm trying to better understand if I can run a standard off the shelf
PCI NIC with a powerpc kernel as the PCI with device tree is not clear
to me.
I don't see many Ethernet drivers having OF support in them so maybe

Hi all,
We are in the process of putting PCI/PCIe into the microblaze
architecture.
In order to not duplicate/fork the PCI code in Powerpc, we're proposing
to move the PCI code from arch/powerpc into drivers/of such that it
would be common code for Powerpc and MicroBlaze.
This would be the 1st

MPC5121 FEC requeries 4-byte alignmnent for TX data buffers.
This patch is a work around that copies misaligned tx packets
to an aligned skb before sending.

Sending a break on the SOC UARTs found in some MPC83xx/85xx/86xx
chips seems to cause a short lived IRQ storm (/proc/interrupts
typically shows somewhere between 300 and 1500 events). Unfortunately
this renders SysRQ over the serial console completely inoperable.
Testing with obvious things like A

Did a quick test of the patchset, seems to work OK (without CONFIG_SWAP or
CONFIG_MODULES). Didn't try with CONFIG_8xx_CPU6.

This set of tries to optimize the TLB code on 8xx even
more. If they work, it should be a noticable performance
boost.
I would be very happy if you could test them for me.

8xx: Optimze TLB Miss handlers
8xx: Avoid testing for kernel space in ITLB Miss.
8xx: Don't touch
This removes a couple of insn's from the TLB Miss
