KVM: selftests: Add helper for checking if running on powerpc pseries LPAR
PowerPC's PAPR L0 does not guarantee H_GUEST_CREATE/H_GUEST_CREATE_VCPU
hcalls to create upto MAX_VCPUS or hundreds of VMs, this is due to
limited resouces at L0 for guest management space. This helper allows us
to skip such tests which creates a lot of VMs/VCPUs, when we are running
nested.
Note that there is no easy way to differentiate between running nested
on PowerNV v/s kvm-on-powervm case. So we use a common helper to detect
any nested case.
The helper is added to the common kvm_util header file to avoid
sprinkling multiple #ifdef __powerpc64__ everywhere.
