On AMD target, when host cache passthrough is disabled we will emulate the guest caches with default values and initialize the shared cpu list of the caches based on vCPU topology. However when host cache passthrough is enabled, the shared cpu list is consistent with host regardless what the vCPU topology is. For example, when cache passthrough is enabled, running a guest with vThreads=1 on a host with pThreads=2, we will get that there are every *two* logical vCPUs sharing a L1/L2 cache, which is not consistent with the vCPU topology (vThreads=1). So let's reinitialize BITs[25:14] of AMD CPUID 8000_001D.EAX based on the actual vCPU topology instead of host pCPU topology. Signed-off-by: Yanan Wang <wangyanan55@huawei.com>
