Say more about the changes. Why the gap to index 4?
You mean why the KVM_ARM_TARGET_CORTEX_A53 is 4?
linux-headers/asm-arm64/kvm.h defines it to 4.
/* Supported Processor Types */
#define KVM_ARM_TARGET_AEM_V8 0
#define KVM_ARM_TARGET_FOUNDATION_V8 1
#define KVM_ARM_TARGET_CORTEX_A57 2
#define KVM_ARM_TARGET_XGENE_POTENZA 3
#define KVM_ARM_TARGET_CORTEX_A53 4

Do you need the = 4? This seems to be a continuous list of indicies
terminated by _TARGET_NONE.
