As noted by Stefan Neis <Stefan.Neis@kobil.com>, we had a recent
regression with EHCI periodic transfers, in some (seemingly not
all that common) cases.
The root cause was that the schedule activation was only loosely
coupled to the addition or removal of transfers, so two different
execution contexts could both think they had to deactivate (or
conversely activate) the schedule. So this fix tightens that
coupling, managing it more like a refcount.

Commit de85422b94, 'USB: fix interrupt
disabling for HCDs with shared interrupt handlers' changed usb_add_hcd()
to strip IRQF_DISABLED from irqflags prior to calling request_irq()
with the justification that such a removal was necessary for shared
interrupts to work properly. Unfortunately, the change in that commit
unconditionally removes the IRQF_DISABLED flag, causing problems on
platforms that don't use a shared interrupt but require IRQF_DISABLED.
This change adds a check for IRQF_SHARED prior to removing the
IRQF_DISABLED flag.
Fixes the PS3 system startup hang reported with recent Fedora and
OpenSUSE kernels.
Note that this problem is hidden when CONFIG_LOCKDEP=y (ps3_defconfig),
as local_irq_enable_in_hardirq() is defined as a null statement for
that config.

I noticed that the "Refactor "if (handshake()) state = HC_STATE_HALT"
patch from earlier this year perpetuated a potential problem: it can
mark the controller as halted when it's still running (but not acting
as, perhaps wrongly, expected).
That caused some hangs and crashes, rather than more polite failure
modes of a truly halted controller. This patch forces a true halt,
and emits a (previously missing) diagnostic.

This patch (as1069c) changes the way OHCI root-hub status-change
interrupts are enabled. Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub. This approach turns out to be subject to races, resulting
in unnecessary polling.
The patch does away with the method entirely. Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present. This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

This patch (as1130) fixes an incompatibility between the new PM
infrastructure and USB power management. We are not allowed to call
drivers' probe routines during a system sleep transition between the
"prepare" and "complete" callbacks, but that's exactly what we do when
a driver doesn't have full suspend/resume support. Such drivers are
unbound during the "suspend" call and reprobed during the "resume" call.
The patch causes the reprobe step to be skipped if the "complete"
callback hasn't been issued yet, i.e., if the interface's
dev.power.status field is not equal to DPM_ON. Thus during the
"resume" callback nothing bad will happen, and during the final
"complete" callback the reprobing will occur as desired.
This fixes the problem reported in Bugzilla #11263.

This patch (as1129) adds support for the new PM callbacks to usbcore.
The new callbacks merely invoke the same old USB power management
routines as the old ones did.
A minor improvement is that the callbacks are present only in the
"USB-device" device_type structure, rather than in the bus_type
structure. This way they will be invoked only for USB devices, not
for USB interfaces. The core USB PM routines automatically handle
suspending and resuming interfaces along with their devices.

This patch (as1128) fixes one of the problems related to the new PM
infrastructure. We are not allowed to register new child devices
during the middle of a system sleep transition, but unbinding a USB
driver causes the core to automatically install altsetting 0 and
thereby create new endpoint pseudo-devices.
The patch fixes this problem (and the related problem that installing
altsetting 0 will fail if the device is suspended) by deferring the
Set-Interface call until some later time when it is legal and can
succeed. Possible later times are: when a new driver is being probed
for the interface, and when the interface is being resumed.

If Indexed Mode register accesses are enabled, the ep0_rxstate()
function calls musb_g_ep0_giveback() before writing to the CSR
register. When control returns to this ep0_rxstate, the index
register contents are over-written. This causes the CSR register
write to fail.
Fixed by writing the correct value into the index register before
writing to the CSR.
This was observed only in ep0_rxstate() with g_ether loaded and
the device connected to a MS Windows host PC. Anticipatively fixed
ep0_txstate() as well.
