# # USB Class driver configuration # comment "USB Device Class drivers" config USB_ACM tristate "USB Modem (CDC ACM) support" depends on TTY ---help--- This driver supports USB modems and ISDN adapters which support the Communication Device Class Abstract Control Model interface. Please read for details. If your modem only reports "Cls=ff(vend.)" in the descriptors in /proc/bus/usb/devices, then your modem will not work with this driver. To compile this driver as a module, choose M here: the module will be called cdc-acm. config USB_PRINTER tristate "USB Printer support" help Say Y here if you want to connect a USB printer to your computer's USB port.

You can use AT commands over this device. To compile this driver as a module, choose M here: the module will be called cdc-wdm. config USB_TMC tristate "USB Test and Measurement Class support" help Say Y here if you want to connect a USB device that follows the USB.org specification for USB Test and Measurement devices to your computer's USB port.

mm: do not export ioremap_page_range symbol for external module
Recently, I've found cases in which ioremap_page_range was used incorrectly, in external modules, leading to crashes. This can be partly attributed to the fact that ioremap_page_range is lower-level, with fewer protections, as compared to the other functions that an external module would typically call. Those include: ioremap_cache ioremap_nocache ioremap_prot ioremap_uc ioremap_wc ioremap_wt ...each of which wraps __ioremap_caller, which in turn provides a safer way to achieve the mapping. Therefore, stop EXPORT-ing ioremap_page_range.
