	  Say Y here if you want to have control over RF switches
	  found on many WiFi and Bluetooth cards.

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

# LED trigger support

	default y if !EXPERT

	depends on RFKILL || !RFKILL
	depends on REGULATOR
	help
          This options enable controlling radio transmitters connected to
          voltage regulator using the regulator framework.

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

config RFKILL_GPIO
	tristate "GPIO RFKILL driver"
	depends on RFKILL
	depends on GPIOLIB || COMPILE_TEST
	default n
	help
	  If you say yes here you get support of a generic gpio RFKILL
	  driver.

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.
