Fix a bug where only half the number of endpoints supported by the
hardware are exposed to gadget. If DEN filed in the DCCPARAMS
register has 'N' then 'N' IN endpoints and 'N" OUT endpoints can be
supported. But only 'N' bidirectional endpoints are added to the
gadget ep_list. This patch also ensures that the data and handshake
transactions of previous setup packet are flushed upon a new setup
packet arrival on ep0.

This patch (as1443) fixes a bug found in many of the USB serial
drivers: They don't set the .usb_driver field in their
usb_serial_driver structure. This field is needed for assigning
dynamic IDs for device matching.
In addition, starting with the 2.6.37 kernel, the .usb_driver field is
needed for proper autosuspend operation. Without it, attempts to open
the device file will fail.

Previously a check was done on an ID register at the base of a CPU's
internal USB registers to determine if system interface regsiters were
present. The check looked for an ID register that had the format
ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to
determine if a MPC5121 or MPC83xx/85xx was being used.
There are two issues with this method:
- The ID register is not defined on the MPC83xx/85xx CPUs, so its
unclear what is being checked on them.
- Newer CPUs such as the P4080 also don't document the ID register, but
do share the same format as the MPC5121. Thus the previous code did
not set 'have_sysif_regs' properly which results in the P4080 not
properly initializing its USB ports.
Using the device tree 'compatible' node is a cleaner way to determine if
'have_sysif_regs' should be set and resolves the USB initialization issue
seen on the P4080.
Tested on a P4080-based system and compile tested on mpc512x_defconfig
with Freescale EHCI driver enabled.

This patch (as1442) fixes a bug in g_printer: Module parameters should
not be marked "__initdata" if they are accessible in sysfs (i.e., if
the mode value in the module_param() macro is nonzero). Otherwise
attempts to access the parameters will cause addressing violations.
Character-string module parameters must not be marked "__initdata"
if the module can be unloaded, because the kernel needs to access the
parameter variable at unload time in order to free the
dynamically-allocated string.

This patch (as1441) fixes a bug in g_printer. The gadget driver, char
device number, and class device should be unregistered in reverse
order of registration. As it is now, when the module is unloaded the
class device gets unregistered first, causing a crash when the unbind
method tries to access it.
This fixes Bugzilla #25882.

This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is
used to compute the size in a dma_alloc_coherent() call, but then it
gets changed later on. As a result, the corresponding call to
dma_free_coherent() passes a different size from the original
allocation. Fix the problem by adjusting ehci->periodic_size before
carrying out any of the memory allocations.

- The setup processing of a DMA descriptor.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

When xhci_discover_or_reset_device() is called after a host controller
power loss, the virtual device may need to be reallocated. Make sure
xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing
the kernel to flush pending I/O while reallocating memory for a virtual
device for a USB mass storage device that's holding the backing store for
dirty memory buffers.

When there's an xHCI host power loss after a suspend from memory, the USB
core attempts to reset and verify the USB devices that are attached to the
system. The xHCI driver has to reallocate those devices, since the
hardware lost all knowledge of them during the power loss.
When a hub is plugged in, and the host loses power, the xHCI hardware
structures are not updated to say the device is a hub. This is usually
done in hub_configure() when the USB hub is detected. That function is
skipped during a reset and verify by the USB core, since the core restores
the old configuration and alternate settings, and the hub driver has no
idea this happened. This bug makes the xHCI host controller reject the
enumeration of low speed devices under the resumed hub.
Therefore, make the USB core re-setup the internal xHCI hub device
information by calling update_hub_device() when hub_activate() is called
for a hub reset resume. After a host power loss, all devices under the
roothub get a reset-resume or a disconnect.
This patch should be queued for the 2.6.37 stable tree.

Synchronize the interrupts instead of free them in xhci_suspend(). This will
prevent a double free when the host is suspended and then the card removed.
Set the flag hcd->msix_enabled when using MSI-X, and check the flag in

and MSI/INTx will be synchronized in suspend_common().

The original code that resumed the USB bus on a port status change would
only do so when there was a device connected to the port. If a device was
just disconnected, the event would be queued for khubd, but khubd wouldn't
run. That would leave the connect status change (CSC) bit set.
If a USB device was plugged into that same port, the xHCI host controller
would set the current connect status (CCS) bit. But since the CSC bit was
already set, it would not generate an interrupt for a port status change
event. That would mean the user could "Safely Remove" a device, have the
bus suspend, disconnect the device, re-plug it in, and then the device
would never be enumerated.
Plugging in a different device on another port would cause the bus to
resume, and khubd would notice the re-connected device. Running lsusb
would also resume the bus, leading users to report the problem "went away"
when using diagnostic tools.
The solution is to resume the bus when a port status change event is
received, regardless of the port status.

dcache_lock no longer protects anything. remove it.

Protect d_subdirs and d_child with d_lock, except in filesystems that aren't
using dcache_lock for these anyway (eg. using i_mutex).
Note: if we change the locking rule in future so that ->d_child protection is
provided only with ->d_parent->d_lock, it may allow us to reduce some locking.
But it would be an exception to an otherwise regular locking scheme, so we'd
have to see some good results. Probably not worthwhile.
