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

if you take a look on other patch on the ML you will see some work done here

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?

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

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?

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 see...

Jean-Christophe already posted a V2 patch (on lakml and linux-usb):
"[PATCH V2] usb/gadget: at91sam9g20 fix end point max packet size"

with proper comment and my "Acked-by".

Is it ok for you?

    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+...

can we have it for the stable kernel at least

all the kernel from the .26 suffer this issue

Please go read Documentation/stable_kernel_rules.txt for how to get
patches into the stable kernel trees.

Resent upon Greg's request.
Based on current linux-next.
Applies cleanly on current linus' tree (2.6.39-rc7+)

BTW, can we imagine it going to mainline before .39-final in a "fixes" pull
request to Linus from a at91 tree?

No, as I don't think this is a bug-fix-only-for-regression, is it?

It looks to be a "fix for new hardware" type thing, right?

And is this really the correct way to do this for the .40 kernel, which
is where I would be queueing this up for?

Not a regression, but a
oh-my-god-how-it-has-been-there-for-such-a-long-time type of bug.

> It looks to be a "fix for new hardware" type thing, right?

Hardware has been merged in kernel for a pretty long time now... But
anyway, I fully understand: this bug has been sitting in the dark for a
handful of kernel revision now, so it can wait for .40...

> And is this really the correct way to do this for the .40 kernel, which

Right. Let's queue it for .40.
