This patch (as1413) changes g_file_storage to avoid generating a bogus automatic serial-number string descriptor. If the user doesn't provide a valid serial number via a module parameter then a warning is logged and the gadget won't have any serial string descriptor at all.

To accomplish this the function to register a gadget driver takes the bind function as a second argument. To make things clearer rename the function to resemble platform_driver_probe. This fixes many section mismatches like WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in reference from the variable printer_driver to the function .init.text:printer_bind() The variable printer_driver references the function __init printer_bind() All callers are fixed.

This patch removes some of the string registration from the Multifunction Composite Gadget as composite layer can handle the iManufacturer and iProduct for us. This also adds the "needs_serial" so that composite layer will issue a warning if user space fails to provide the iSerialNumber module parameter.

This patch removes string registration from the Mass Storage Gadget. With recent changes to the composite framework, all that we need is handled by the composite layer. This means composite registers a string ID for manufacturer and product. This also adds the "needs_serial" so that composite layer will issue a warning if user space fails to provide the iSerialNumber module parameter.

Michal Nazarewicz authored
The iManufatcurer, iProduct and iSerialNumber composite module parameters were only used when the gadget driver registers strings for manufacturer, product and serial number. If the gadget never bothered to set corresponding fields in USB device descriptors those module parameters are ignored. This commit makes the parameters work even if the strings ID have not been assigned. It also changes the way IDs are overridden -- what IDs are overridden is now saved in usb_composite_dev structure -- which makes it unnecessary to modify the string tables the way previous code did. The commit also adds a iProduct and iManufatcurer fields to the usb_composite_device structure. If they are set, appropriate strings are reserved and added to device descriptor. This makes it unnecessary for gadget drivers to maintain code for setting those. If iProduct is not set it defaults to usb_composite_device::name; if iManufatcurer is not set a default "<system> <release> with <gadget-name>" is used. The last thing is that if needs_serial field of usb_composite_device is set and user failed to provided iSerialNumber parameter a warning is issued.

This patch removes some of the string registration from the FunctionFS Gadget as composite layer can handle the iManufacturer and iProduct for us. It also removes some of the module parameters which were redundant as well as changes the name of others to better much the module parameter of the composite layer. Other then that, it also fixes formatting of multiline comments to match the coding style.

Add new driver to access the SAM-BA boot application of Atmel AT91SAM devices. The SAM-BA firmware cannot handle merged write requests so we cannot use the generic write implementation (which uses the port write fifo).

This adds support for the USB transceiver driver in the Langwell chipset used on the Intel MID platforms. It folds up the original patch set which includes basic support for the device, PHY low power mode (Please notice that there is a limitation, after we drive VBus down, 2ms delay is required from SCU FW to sync up OTGSC register with USBCFG register), software timers (the hardware timers do not work in low power mode), HNP, SRP.

If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.

When running make clean, Kbuild doesn't process the .config file, so nothing generates a platform-y variable. We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned. This is change to an append operation '+=' to allow cavium-octeon to be cleaned.

kvm reloads the host's fs and gs blindly, however the underlying segment descriptors may be invalid due to the user modifying the ldt after loading them. Fix by using the safe accessors (loadsegment() and load_gs_index()) instead of home grown unsafe versions. This is CVE-2010-3698. KVM-Stable-Tag.
