Hi,
Below is a patch to fix a couple of issues with fake numa node creation
on ppc:
1) Presently, fake nodes could be created such that real numa node
boundaries are not respected. So a node could have lmbs that belong to
different real nodes.
2) The cpu association is broken. On a JS22 blade

You don't want to simulate cpu less nodes since they do have affinity to
ranges of

Hi everyone~
In ther linux kernel code, I found the reloc_offset.
{{{

_GLOBAL(reloc_offset)

Hi John,
on my mpc512x custom board I have non-working USB after the kexec
syscall. I've traced it down to the ehci_turn_off_all_ports() which is
called from within ehci_shutdown(). If I omit ehci_turn_off_all_ports()
it works fine. The content of the portstatus register is the same after

Usually u-boot sends a phy request in its network init routine. An uboot
without network support doesn't do it and I endup without working
network. I still can switch between 10/100Mbit (according to the LED on
the hub and phy registers) but I can't send or receive any data.
At this point I'm not

Right, I'm proposing an alternate mapping scheme (which we've used for

Hi Chris,
I am having a problem similar to what you described in this discussion.
We are using the ppc arch with 2.6.24 with CONFIG_SEQUOIA with compiles
arch/ppc/kernel/head_44x.c (quite different
from /arch/powerpc/kernel/head_32.S). I would like to apply your
backporting patch to this
The former is no longer really accurate with the swiotlb case now
a possibility. I also move it into dma-mapping.h - it no longer
needs to be in dma.c, and there are about to be some more accessors
that should all end up in the same place.

Sometimes this is used to hold a simple offset, and sometimes
it is used to hold a pointer. This patch changes it to a union containing
void * and dma_addr_t. get/set accessors are also provided, because it was
getting a bit ugly to get to the actual data.

Hello,
I have a question regarding reading PCI bus registers from a user space
application running on a PPC SBC. Seeing as though the PCI bus is little endian
and PPC is big endian is it typical that one must perform a byte swap on all 16
and 32 bit register reads?
I've found this is true

Hi Tjernlund,
Thanks a lot for the reply.
I checked in my code regarding to the invalidate/flushing of the
data cache. In the fec_init its been done by calling the sequence
/* Make it uncached.
*/
pte = va_to_pte(mem_addr);
pte_val(*pte) |= _PAGE_NO_CACHE;
