category: feature
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I78KDD
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8d75f7b4a3dfd5714a5dc87cfdaa27bd2d14aa48

Intel-SIG: commit 8d75f7b4 platform/x86: intel-uncore-freq: Prevent driver loading in guests.
Backport for intel-uncore-freqe driver

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

Loading this driver in guests results in unchecked MSR access error for
MSR 0x620.

There is no use of reading and modifying package/die scope uncore MSRs
in guests. So check for CPU feature X86_FEATURE_HYPERVISOR to prevent
loading of this driver in guests.
