I'm not sure what this piece of code is doing in the UHCI driver.  It
looks like someone envisioned queuing several URBs for the same endpoint
simultaneously.  Anyway, the driver can't do that and this code can never
run.

This patch implements the endpoint_disable method for the UHCI driver, as
you requested a while back.  It guarantees that during unbinding events
(disconnect, configuration change, rmmod) the UHCI driver will have
finished using every URB for the interface being unbound.  It doesn't
quite guarantee that the completion handlers will have finished running,
but it would take a pretty unlikely race to violate that assumption.  (I
think it's the same with the OHCI and EHCI drivers.)

Despite the patch numbering this one applies _after_ as249, which is a
more important bugfix.

Thank you for sending this in.  Greg and Pete, here's the patch.

It looks safe to conclude that the unusual_devs.h entries for the Minolta
DiMAGE 7x cameras aren't needed.  (Michael has tested the 7Hi and it's
definitely unnecessary.)  The two other DiMAGE entries probably aren't
needed either, but we don't have any evidence of that so I'm leaving them.

The patch lets HCDs report the root hub remote wakeup feature to usbcore
through config descriptors, and lets usbcore say whether or not remote
wakeup (of host from sleep, by devices) should be enabled.

Both OHCI and UHCI HCDs have some remote wakeup support already; I'm not
too sure how well it works.  Given (separate) patches, their root hubs
can start to act more like other hubs in this area too.  That'll make
it easier to start using USB suspend mode.

In 2.6, ISO transfers on USB require a value for urb->interval ... which
usbfs didn't provide (until this patch), or let user mode drivers specify.

This patch initializes the urb->interval from the endpoint's descriptor,
so ISO transfers should now work from userspace.  It also fixes a related
problem for interrupt transfers.

If a filesystem's ->writepage implementation repeatedly refuses to write the
page (it keeps on redirtying it instead) (reiserfs seems to do this) then the
writeback logic can get stuck repeately trying to write the same page.

Fix that up by correctly setting wbc->pages_skipped, to tell the writeback
logic that things aren't working out.

Since symlink.c uses "name" field of a kobj when it calculates the
length,  it gets a wrong value if the kobj's name  has more than 20
charathers.  A correct way to do that is to call kobject_name(kobj)
instead of using kobj->name directly.

this patch (2.4 & 2.6) fixes a bug about the timeout value. The formula
used to calculate jiffies from timeout is wrong.
The new formula is ok and takes care of integer computation/rounding.
There is the same bug in the tiglusb.c module which will be fixed by another
patch.

Handle some PL-2301/2302 devices better.

I just checked out the latest 2.6.6-rc1-mm1 to see that the ID patch for
ftdi has applied cleanly, but apparently someone was faster and in the
combined ID table our ID's were missing.
Most probably the patch program got confused and applied the hung at wrong
spot..

Attached is a patch that places that 2 lines in the correct spot.

Hi,

this patch (cumulative; 2.4 & 2.6) fixes another bug in the tiglusb
driver. The formula used to calculate jiffies from timeout is wrong.
The new formula is ok and takes care of integer computation/rounding.
This is the same kind of bug than in the tipar char driver.

Warnings aren't terribly important in and of themselves, but there
isn't really much the warning tells us to do here, so it would appear
that caving in to the compiler is the thing to do for now.

Various build fixes:  64bit (Andrew Morton), static linking,
broken on big-endian, etc.

Tighten up the integration with the main "ether" driver, so
state transitions and host ethernet addresses are shared too.
Add missing spinlock calls around RNDIS command outcall,
fix GET_INTERFACE issue, host mustn't clobber netdev flags.

Minor code cleanups.

Cope better when PCI misbehaves badly and registers misbehave:

    - terminate some loops before they get to infinity
       * capability scan
       * port reset
    - after init failure, memory may already be cleaned up

Some systems have been reporting such problems after ACPI resume.

This replaces current_thread_info()->cpu in i386' init_IRQ() by the
equivalent smp_processor_id().

Reduces overhead on UP, and makes the code cleaner.

This simplifies the Pentium M quirk code in nmi.c, and eliminates an
unnecessary apic_read().

Local APIC accesses are not zero-cycle; let's not inflict more damage
than we must.
