[PATCH V2] arm64/cpufeature: Validate hypervisor capabilities during CPU hotplug

2020-05-07 Thread Anshuman Khandual
This validates hypervisor capabilities like VMID width, IPA range for any hot plug CPU against system finalized values. While here, it factors out get_vmid_bits() for general use and also defines ID_AA64MMFR0_PARANGE_MASK. Cc: Catalin Marinas Cc: Will Deacon Cc: Marc Zyngier Cc: Mark Rutland C
