Some AArch64 system registers report UNDEFINED behaviours if accessed from EL2 or EL3 in a non-EL2 Host enabled (HCR_EL2.E2H == 0) environment. Examples of these are seen in the Generic Timer system registers, namely CNTP_CTL_EL02 or CNTKCTL_EL12. This patch provides an ISA filter for specifying the above condition.
