The current form of DO_KVM macro restricts its use to one call per input
parameter set. This is caused by kvmppc_resume_\intno\()_\srr1 symbol
definition.
Duplicate calls of DO_KVM are required by distinct implementations of
exeption handlers which are delegated at runtime.

Not sure I understand what you're trying to achieve here. Please elaborate ;)

On 64-bit book3e we compile multiple versions of the TLB miss handlers,
and choose from them at runtime.  Without this patch, we get duplicate
label errors if more than one variant of the same exception uses DO_KVM.
