[Bug c/36359] [Regression] compile error in linux-kernel 2.6.26-rc4 with -O2

I was able to find the function in which the error occurs. It's usb_submit_urb
in drivers/usb/core/urb.c I think.
The command:
$ gcc -c -save-temps drivers/usb/core/urb.c -I include
executed in the linux-kernel main directory gives me the attached urb.i. Is
that what you need? Executing this gives me the following errors, though:
