Try git grep hypercall arch/x86/kvm.
Take a look at arch/x86/kvm/x86.c kvm_set_msr_common() and kvm_emulate_hypercall(). Some of the KVM time-keeping, minimal HyperV support, and async page faults live there. Also see arch/x86/include/asm/kvm_para.h.
Hypercalls are architecture-specific so if you are interested in ppc or s390, check those arch directories.
