	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.

powerpc/mm: Fix spurrious segfaults on radix with autonuma
When autonuma (Automatic NUMA balancing) marks a PTE inaccessible it clears all the protection bits but leave the PTE valid. With the Radix MMU, an attempt at executing from such a PTE will take a fault with bit 35 of SRR1 set "SRR1_ISI_N_OR_G". It is thus incorrect to treat all such faults as errors. We should pass them to handle_mm_fault() for autonuma to deal with. The case of pages that are really not executable is handled by the existing test for VM_EXEC further down. That leaves us with catching the kernel attempts at executing user pages. We can catch that earlier, even before we do find_vma. It is never valid on powerpc for the kernel to take an exec fault to begin with. So fold that test with the existing test for the kernel faulting on kernel addresses to bail out early.
