We already check KVM_CAP_IRQFD in generic once enable CONFIG_HAVE_KVM_IRQFD,
kvm_vm_ioctl_check_extension_generic()
|
+ switch (arg) {
+ ...
+ #ifdef CONFIG_HAVE_KVM_IRQFD
+ case KVM_CAP_IRQFD:
+ #endif
+ ...
+ return 1;
+ ...
+ }
|
+ kvm_vm_ioctl_check_extension()
So its not necessary to check this in arch again, and also fix one typo,
s/emlation/emulation.
