Subject: [Linux-ia64] CONFIG_USB_UHCI=y not possible?

When I try to change CONFIG_USB_UHCI from a module to static (=m to =y),
I get:

    drivers/usb/usbdrv.o: In function `alloc_uhci':
    drivers/usb/usbdrv.o(.text.init+0x7e2): relocation truncated to fit: PCREL21B uhci_pci_remove

I don't see anything obvious (to me) with the disassembly:

     7e0:   11 60 01 40 00 21       [MIB]       mov r44=r32
     7e6:   00 00 00 02 00 00                   nop.i 0x0
     7ec:   08 00 00 50                         br.call.sptk.many b0~0 <alloc_uhci

It's see the same problem in a different kernel, with the same code
at a different offset (0x672).

Anyone have any idea what's going on with this?

Also, I have some recollection seeing something that said that USB
support has to be a module, maybe because it doesn't see the devices
otherwise?  Any truth to this?

Thanks,

John
