Here's an EHCI update, I'll send separate patches to sync 2.4 with
this version.  Changes in this version include:

  - An earlier locking update would give trouble on SPARC, where
    irqsave "flags" aren't flags.  This resolves that issue by
    adding a module parameter to limit work done with irqs off.
    (Some net drivers do the same thing.)

  - Optionally (now #ifdef DEBUG) collects some statistics on IRQs
    and URBs.  There are more IAA interrupts than I want to see,
    during extended usb-storage loading.

  - Adds a commented-out workaround for a problem I've seen on one
    VT8235.  Seems likely an issue with this specific motherboard;
    another tester hasn't reported such issues.

  - Includes the jiffies time_after() patch from Tim Schmielau.

  - Minor tweaks to the hcd portability (get rid of another #if).

  - Minor doc/diagnostic/... updates
