	help
	  Say Y here if you want to use the Atmel AT73C213 external DAC. This
	  DAC can be found on Atmel development boards.

	  This driver requires the Atmel SSC driver for sound sink, a
	  peripheral found on most AT91 and AVR32 microprocessors.

	  To compile this driver as a module, choose M here: the module will be
	  called snd-at73c213.

	depends on SND_AT73C213
	default "48000"
	range 8000 50000
	help
	  Sets the target bitrate for the bitrate calculator in the driver.
	  Limited by hardware to be between 8000 Hz and 50000 Hz.

	  Set to 48000 Hz by default.

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.
