Hi Sarah,
This series addresses the endian issues with the xHCI driver, and has brought
lovely USB 3 to PPC. :-) I've tested various types of traffic on ppc4xx and
POWER7 and (some sound driver bugs notwithstanding) all seems fine. Also
addresses an ordering problem we found and the recursive nature of the event
handling, plus the addition of some debug.
This should apply to 2.6.38/Linus' tree.
Thanks!
Matt

Thanks for doing this work, Matt! I appreciate it.

You say that these apply against 2.6.38, but recently a lot of xHCI
changes went into Linus' tree to support USB 3.0 hubs in 2.6.39. Will
these patches still apply against Linus' latest tree? If not, I suggest
you base your patches against Greg KH's usb-linus branch, as that's my
tree base:
http://git.kernel.org/?p=linux/kernel/git/gregkh/usb-2.6.git;a=shortlog;h=refs/heads/usb-linus
Also, I haven't read too far into the patches, but the first patch seems
to have several one or two letter variable names, like "f" and "di".
Can you make those variable names more descriptive? Thanks.

Hey, no worries! I've got some $3 USB speakers I wanted to connect to the
$15,000 POWER server, you know how it goes.

Sorry, I wasn't too explicit about that; I'd meant "Linus' tree as of todayish"
and I believe I caught said USB 3.0 changes, but I'll rebase from usb-linus
anyway to make sure we're fine.
Also, I haven't read too far into the patches, but the first patch seems

Sure; they were single-use throwaways to break long RMW lines but I've rejiggled
& removed them.
Thanks for looking, I'll repost v3 with tidyups.
Cheers,
Matt
