config KVM_GUEST

	bool "KVM Guest Kernel"

	depends on !64BIT && BROKEN_ON_SMP

	help

	  Select this option if building a guest kernel for KVM (Trap & Emulate)

	  mode.

	int "Count/Compare Timer Frequency (MHz)"

	depends on KVM_GUEST

	help

	  Set this to non-zero if building a guest kernel for KVM to skip RTC

	  emulation when determining guest CPU Frequency. Instead, the guest's

	  timer frequency is specified directly.
