From: Catalin Marinas <catalin.marinas@xxxxxxx> With the recent rewrite of the arm64 KVM hypervisor code in C, enabling certain options like KASAN would allow the compiler to generate memory accesses or function calls to addresses not mapped at EL2. This patch disables the compiler instrumentation on the arm64 hypervisor code for gcov-based profiling (GCOV_KERNEL), undefined behaviour sanity checker (UBSAN) and kernel address sanitizer (KASAN).
