CVE: NA

-----------------------------------------------------

Since the reset function is in kvm_intel module instead of kvm
module, the attribute weak function in kvm_main.c could not be found, which
would cause st_max in X86 never be refreshed.
The solution is to define the reset function in x86.c under the kvm module.
