Greg: The following lengthy series contains a set of changes and enhancements to ehci-hcd. The most notable changes include moving from regular kernel timers to high-resolution timers, and getting rid of long polling loops with interrupts disabled.
Other changes include removal of unnecessary code, adding symbolic constants, renaming a few fields, general cleanups, checking for a few unlikely races, not assuming the controller has died when a state change takes longer than expected, unlinking multiple async QHs together, unlinking interrput QHs correctly, and so on... The end result will be (I hope!) a better behaved driver.
