[linux-usb-devel] What does this code snippet check for?

[Yang, Neil L]

Hello again!

In usb-ohci.c (line 2854) there is a check (which is only used if
CONFIG_SA1111 is defined):

        if( (((unsigned long)td->hwCBP) & 0x100000) ) {
                printk("td_fill() hwCBP %p, a20!\n", (void *)td->hwCBP);

        }

Could someone please explain what this message is telling/warning me of?
What does the a20 mean?  Does this check suggest the pointer is to an
invalid address?

Thanks,
Neil
