# # USB/ATM DSL configuration # menuconfig USB_ATM tristate "USB DSL modem support" depends on ATM select CRC32 default n help Say Y here if you want to connect a USB Digital Subscriber Line (DSL) modem to your computer's USB port. You will then need to choose your modem from the list below. To compile this driver as a module, choose M here: the module will be called usbatm. if USB_ATM config USB_SPEEDTOUCH tristate "Speedtouch USB support" select FW_LOADER help Say Y here if you have an SpeedTouch USB or SpeedTouch 330 modem. In order to use your modem you will need to install the two parts of the firmware, extracted by the user space tools; see for details. To compile this driver as a module, choose M here: the module will be called speedtch. config USB_CXACRU tristate "Conexant AccessRunner USB support" select FW_LOADER help Say Y here if you have an ADSL USB modem based on the Conexant AccessRunner chipset.

To compile this driver as a module, choose M here: the module will be called ueagle-atm. config USB_XUSBATM tristate "Other USB DSL modem support" help Say Y here if you have a DSL USB modem not explicitly supported by another USB DSL drivers. In order to use your modem you will need to pass the vendor ID, product ID, and endpoint numbers for transmission and reception as module parameters. You may need to initialize the modem using a user space utility (a firmware loader for example).

perf/x86/intel/rapl: Make package handling more robust
The package management code in RAPL relies on package mapping being available before a CPU is started. This changed with: 9d85eb9119f4 ("x86/smpboot: Make logical package management more robust") because the ACPI/BIOS information turned out to be unreliable, but that left RAPL in broken state. This was not noticed because on a regular boot all CPUs are online before RAPL is initialized. A possible fix would be to reintroduce the mess which allocates a package data structure in CPU prepare and when it turns out to already exist in starting throw it away later in the CPU online callback. But that's a horrible hack and not required at all because RAPL becomes functional for perf only in the CPU online callback. That's correct because user space is not yet informed about the CPU being onlined, so nothing caan rely on RAPL being available on that particular CPU. Move the allocation to the CPU online callback and simplify the hotplug handling. At this point the package mapping is established and correct. This also adds a missing check for available package data in the event_init() function.
