[gentoo-dev] 2.6.11-gentoo-r7: If USB core API (usbcore) is built-in, it conflicts with the rest of usb-dependent modules

Hi,

After some talk to gregkh, I've decided to send this message as it might
give some light regarding the breakage of the USB modules when usbcore
is built-in instead of compiled as module.

Modules that are breaking with CONFIG_USB=y :

- audio, bfusb, bcm203x, bpa10x, hci_usb, usblp, usb-midi, cdc_acm,
   uhci-hcd, ohci-hcd, ehci-hcd, usb-storage...

For those, the core API symbols that follow are missing as of the
built-in selected option:

usbserial: Unknown symbol usb_alloc_urb
usbserial: Unknown symbol usb_free_urb
usbserial: Unknown symbol usb_register
usbserial: Unknown symbol usb_put_dev
usbserial: Unknown symbol usb_get_dev
usbserial: Unknown symbol usb_submit_urb
usbserial: Unknown symbol usb_match_id
usbserial: Unknown symbol usb_control_msg
usbserial: Unknown symbol usb_deregister
usbserial: Unknown symbol usb_kill_urb

The symbols are in the System map:

c02fd7b0 T usb_free_urb
c02fd7d0 T usb_get_urb
c02fd800 T usb_submit_urb
c02fdaa0 T usb_unlink_urb
c02fdb40 T usb_kill_urb
(...)

Greg suggested on fixing the Kconfig but I'm not sure if this a
Gentoo-only issue, or it's widely. Thus, if it needs to be fixed, let me
know and I'll get over it ASAP as it might be a blocking issue in
certain cases.

(It doesn't seem to be a good idea to let all the USB-related drivers
getting built-in)

Thanks in advance,
cheers.
