[PATCH 0/2] KVM: x86: Check hypercall's exit to userspace generically

Posted by Binbin Wu 1 year, 7 months ago

Currently in kvm_emulate_hypercall, KVM_HC_MAP_GPA_RANGE is checked
specifically to decide whether a KVM hypercall needs to exit to userspace
or not.  Do the check based on the hypercall_exit_enabled field of
struct kvm_arch.

Also use the API is_kvm_hc_exit_enabled() to replace the opencode.
