config KVM_GUEST
bool "KVM Guest Kernel"
depends on CPU_MIPS32_R2
depends on !64BIT && BROKEN_ON_SMP
help
Select this option if building a guest kernel for KVM (Trap & Emulate)
mode.
config KVM_GUEST_TIMER_FREQ
int "Count/Compare Timer Frequency (MHz)"
depends on KVM_GUEST
default 100
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.

bool "48 bits virtual memory"
