HEADSUP!!! USB MFC committed..

[Yoshihiko Sarumaru]

Hello Julian,

I report you about a USB problem that would be occur with my
laptop after you MFC'ed USB stuff.

With GENERIC kernel, it is fine and there are no changes from
before, but with no usb kernel + usb.ko + umass.ko, it would be
panic everytime on boot.

It is not depend on umass. The panic would be happen when I
didn't load umass.ko but ucom.ko + umodem.ko and plug USB modem
(PHS phone).

| Preloaded elf kernel "kernel.nousb" at 0xc042b000.
| Preloaded elf module "usb.ko" at 0xc042b0b0.
| Preloaded elf module "umass.ko" at 0xc042b14c.

| Fatal trap 12: page fault while in kernel mode

| current process         = 0 (swapper)

With USB built-in kernel, it will be like this:
| Preloaded elf kernel "kernel.withusb" at 0xc0434000.
| Preloaded elf module "ucom.ko" at 0xc043409c.
