Sorry this is a bug fix for the current rc and 2.6.38 and older stable tree

How could I apply this to the tree for the .40 release then?
it's also the case these patch apply from kernel v2.6.26 to above

for the 2.6.40 we will rewrite the soc init so we may chane this in .40 or .41

That makes no sense, how can I go back in time and apply this to an
older kernel version?

I known we just need for the longterm and stable tree
and the .39-rc8

Please provide a patch that I can apply against the linux-next tree if
you want this change to be accepted.
it's appy to the -next

I have no idea what you are trying to say here.

Care to resend this patch, the correct one, that I can apply to my
usb-next tree for merging in the .40 merge cycle?
It does apply on the linux-next
and previous kernel version

and this patch is a fix for the current kernel
so I would like to have it for this release and the stable tree

No, I can't apply it because of the comments above Sergei.  Please fix
that and get his approval and then I will be able to apply it.

I'm OK with applying the patch to 2.6.39 actually. If I understood correctly, the code will be reworked to get rid of cpu_is_*() for 2.6.40+...

thanks,

greg k-h

WBR, Sergei
