Long before this driver went into mainline, it had support for
multiple TX queues per port, with lockless TX enabled. Since Linux
did not know anything of this, filling up any hardware TX queue would
stop the core TX queue and multiple hardware TX queues could fill up
before the scheduler reacted. Thus it was necessary to keep a count
of how many TX queues were stopped and to wake the core TX queue only
when all had free space again.
The driver also previously (ab)used the per-hardware-queue stopped
flag as a counter to deal with various things that can inhibit TX, but
it no longer does that.
Remove the per-channel tx_stop_count, tx_stop_lock and
per-hardware-queue stopped count and just use the networking core
queue state directly.

I noticed that one of the post-2.6.36 patches broke runtime PM of the
r8169 on my MSI Wind test machine in such a way that the link was not
brought up after reconnecting the network cable.
In the process of debugging the issue I realized that we only should
invoke the runtime PM functions in rtl8169_check_link_status() when
link change is reported and if we do so, the problem goes away.
Moreover, this allows rtl8169_runtime_idle() to be simplified quite
a bit.

After a few unsuccessful NFS mount attempts in which the client and
server cannot agree on an authentication flavor both support, the
client panics. nfs_umount() is invoked in the kernel in this case.
Turns out nfs_umount()'s UMNT RPC invocation causes the RPC client to
write off the end of the rpc_clnt's iostat array. This is because the
mount client's nrprocs field is initialized with the count of defined
procedures (two: MNT and UMNT), rather than the size of the client's
proc array (four).
The fix is to use the same initialization technique used by most other
upper layer clients in the kernel.
Introduced by commit 0b524123, which failed to update nrprocs when
support was added for UMNT in the kernel.

OMAP4430 supports UTMI and ULPI types of transceiver interface.
In UTMI mode: The PHY is embedded within OMAP4430. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.
There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.
musb driver is register for blocking notifications from the transceiver
driver to get the event notifications for connect/disconnect and ID-GND.
Based on these events call the transceiver init/shutdown function to
configure the transceiver to toggle the VBUS valid, session end and ID_GND
signals to musb and power on/off the internal PHY.
For ID_GND event notifications, toggle the ID_GND signal and then wait for
musb to be configured as "A" device, and then call the transceiver function
to set the VBUS.
In OTG mode and musb as a host, When the Micro A connector used, VBUS is turned on
and session bit set. When the device is connected, enumeration goes through.
When the device disconnected from the other end of the connector(ID is still grounded),
link will detect the disconnect and end the session. When the device is connected back,
there are no events generated in the TWL6030-usb, and link is already down.
So the device is not detected. Removed the session bit disable code which
will recognize the connect of the device.
Limitation: In OTG host mode, if device is connected during boot, it does not get
detected. If disconnect and connect it back or connect after boot only it works.
Fix for this, I will submit seperate patch later.

setup_local_APIC() is used to setup local APIC early during CPU
initialization and already assumes that preemption is disabled on
entry. However, The function unnecessarily disables and enables
preemption and uses smp_processor_id() multiple times in and out of
the nested preemption disabled section. This gives the wrong
impression that the function might be able to handle being called with
preemption enabled and/or migrated to another processor in the middle.
Make it clear that the function is always called with preemption
disabled, drop the confusing preemption disable block and call
smp_processor_id() once at the beginning of the function.

Adding the twl6030-usb transceiver support for OMAP4 musb driver.
OMAP4 supports 2 types of transceiver interface.
1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.
There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.
The internal transceiver has functional clocks and
powerdown bits to powerdown the PHY for power saving.
Since there is no option available for having 2 transceiver drivers
for one USB controller, internal PHY specific APIs are passed through
plaform_data function pointers to use in the twl6030-usb transceiver
driver.
2. ULPI interface is provided for off-chip transceivers.

With TWL6030-usb, VBUS SESS_VLD and SESS_END events are not generated
as expected. When these interrupts are enabled, charger VBUS detection
interrupt does not get generated. So USBOTG has to be dependent on charger
VBUS interrupts.
So added one bit for USBOTG and changed the handler to call the
USBOTG handler whenever there is a charger VBUS interrpt.
VBUS SESS_VLD and SESS_END event generation issue is under debug with
HW team. This fix might not be required once after fixing the issue.
