* USB: gadget: g_multi: code clean up and refactoringMichal Nazarewicz2010-08-10
| | | | | | | | | | | | | | | The Multifunction Composite Gadget have been cleaned up and refactored so hopefully it looks prettier and works at least as good as before changes. A Kconfig has also been fixed to make it impossible to build FunctionFS gadget with no configurations. With this patch, if RNDIS is not chosen by the user CDC is force-selected.

* USB: gadget: composite: usb_string_ids_*() functions addedMichal Nazarewicz2010-08-10
| | | | | | | | | | | | | | | | | usb_string_ids_tab() and usb_string_ids_n() functions added to the composite framework. The first accepts an array of usb_string object and for each registeres a string id and the second registeres a given number of ids and returns the first. This may simplify string ids registration since gadgets and composite functions won't have to call usb_string_id() several times and each time check for errer status -- all this will be done with a single call.

| | | | | | | | | | | | | | | | compat_ioctl does not use the BKL, so I assume that the native function does not need it either.

* USB-BKL: Remove BKL use for usb serial driver probingAndi Kleen2010-08-10
| | | | | | | | | | | | | | | | | | | | | | The usb serial driver initialization tried to use the BKL to stop driver modules from unloading, but that didn't work anyways. There was already some code to do proper try_module_get, but it was conditional on having a new probe interface. I checked all the low level drivers and they all have proper .owner = THIS_MODULE, so it's ok to always use. The other problem was the usb_serial_driver_list needing protection by a lock. This was broken anyways because unregister did not necessarily have the BKL. I extended the extending table_lock mutex to protect this case too. With these changes the BKL can be removed here.

* USB: EHCI: make CONFIG_USB_EHCI_TT_NEWSCHED default to YAlan Stern2010-08-10
| | | | | | | | | | | | | | | | | | | This patch (as1382) changes the USB_EHCI_TT_NEWSCHED Kconfig option to be non-experimental and to default to Y. This option has existed for a long time, and I have not heard any complaints concerning it. By contrast, several people have reported that their devices could be made to work only by enabling the option. The point of changing the default is to cause the option to be enabled by distros that simply use the default settings for esoteric things like this. This change was motivated by Bugzilla #15649.

* USB: UHCI: acquire spinlock before calling start_rh()Alan Stern2010-08-10
| | | | | | | | | | | | | | | | | | This patch (as1392) fixes a bug in uhci-hcd: The start_rh() routine is supposed to be called with the private spinlock held. If an IRQ comes in at just the wrong time, the driver will think the controller has died when in fact it simply hasn't start yet. The patch also addresses some issues that may prevent an URB from being unlinked after the controller has stopped. This is an abnormal occurrence (ordinarily the controller stops only when the entire bus is suspended and hence there are no active URBs), so the pathways haven't gotten much testing. These two changes may be a little more than is strictly necessary, but clearly they won't hurt.

* USB: add check to detect host controller hardware removalAlan Stern2010-08-10
| | | | | | | | | | | | | | | | | This patch (as1391) fixes a problem that can occur when USB host controller hardware is hot-unplugged. If no interrupts are generated by the unplug then the HCD may not realize that the controller is gone, and the subsequent unbind may hang waiting for interrupts that never arrive. The solution (for PCI-based controllers) is to call the HCD's interrupt handler at the start of usb_hcd_pci_remove(). If the hardware is gone, the handler will realize this when it tries to read the controller's status register.

* USB: don't stop root-hub status polls too soonAlan Stern2010-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1390) fixes a problem that crops up when a UHCI host controller is unbound from uhci-hcd while there are still some active URBs. The URBs have to be unlinked when the root hub is unregistered, and uhci-hcd relies upon root-hub status polls as part of its unlinking procedure. But usb_hcd_poll_rh_status() won't make those status calls if hcd->rh_registered is clear, and the flag is cleared _before_ the unregistration takes place. Since hcd->rh_registered is used for other things and needs to be cleared early, the solution is to add a new flag (rh_pollable) and use it instead. It gets cleared _after_ the root hub is unregistered. Now that the status polls don't end too soon, we have to make sure they also don't occur too late -- after the root hub's usb_device structure or the HCD's private structures are deallocated. Therefore the patch adds usb_get_device() and usb_put_device() calls to protect the root hub structure, and it adds an extra del_timer_sync() to prevent the root-hub timer from causing an unexpected status poll. This additional complexity would not be needed if the HCD framework had provided separate stop() and release() callbacks instead of just stop(). This lack could be fixed at some future time (although it would require changes to every host controller driver); when that happens this patch won't be needed any more.

The actions it takes ought to be exactly the same as those taken by usb_remove_hcd(), but they aren't. In one case (removal of the usb_bus_attr_group), the two routines are brought into agreement by changing usb_remove_hcd(). All the other discrepancies are fixed by changing usb_add_hcd().

For example, for kernel XIP, detecting can cause NOR enter a mode instructions can not be fetched right, which will make kernel crash. 3. For a new probe which is not listed in the rom_probe_types, if users assign it in board files, physmap can still probe it.
