Improve selftests' error reporting when opening a file fails, e.g. so that
failure to access a module param spits out a message about KVM not being
loaded, instead of a cryptic message about a param not being supported.
Sean Christopherson (4):
KVM: selftests: Verify KVM is loaded when getting a KVM module param
KVM: selftests: Add __open_path_or_exit() variant to provide extra
help info
KVM: selftests: Play nice with EACCES errors in open_path_or_exit()
KVM: selftests: Print a more helpful message for EACCESS in access
