I believe that the basic premise is that you should provide a directly
reachable copy of the save/rstore functions, even if this means that
you need several copies of the functions.
I just fixed a very similar problem with grub2 in fact. It was using r0
and trashing the saved LR that way.

I blame Mikey for this. He elevated my slightly dubious testcase:
# dd if=/dev/zero of=/dev/null bs=1M count=1

zeros. So lets improve __clear_user some more.
As Paul suggests we can use dcbz for large lengths. This patch
When PCI probe flag PCI_REASSIGN_ALL_RSRC has been passed into PCI
core, it's hoped that all resources to be reassigned by PCI core.
As to particular P2P (PCI-to-PCI) bridge, the size of the corresponding
BAR (I/O, MMIO, prefetchable MMIO) is calculated by the resources
required by the PCI devices

Emulators such as BDI2000 and CodeWarrior needs to have MSR_DE set
in order to support break points for booke archs.
This adds MSR_DE for kernel space only, protected by CONFIG_BDI_SWITCH

Hi All,
I'm trying to bring-up a PCIe based NIC(e1000e) card on a PowerPC-440 based
board, I'm able to list this device under lspci from the user space, but the
driver probe fails and looks like mmio mapping doesn't look right. Following is
the bootlog of the kernel. Can anyone point out what i

This patch removes redundant pointer to struct usb_endpoint_descriptor which
were missed in commit 79149b8:
usb: gadget: Update fsl_udc_core to use usb_endpoint_descriptor inside the
struct usb_ep
Due to clock framework regressions, this patch is only compile tested!

Hello all,
I am currently working on the Freescale P2020RDB-PCA Board, which has been
delivred with the linux-2.6.35 kernel. I succeed in re-generating my own uImage
in 2.6.35 thanks to ELDK, but when I want to move on to a newer or older
version of linux, the system does not respond any longer

As I was adding code that affects all archs, I started testing function
tracer against PPC64 and found that it currently locks up with 3.4
kernel. I figured it was due to tracing a function that shouldn't be, so
I went through the following process to bisect to find the culprit:

Hi Cedric MAUSSIRE,
P2020RDB-PCA Board gets supported since kernel 3.3 in mainline code.
Are you sure the board works on kernel 2.6.35?
