Subject[PATCH 1/1] x86/hyper-v: Fix a merge error
Date
From: "K. Y. Srinivasan" <kys@microsoft.com>

When the mapping betwween the Linux notion of CPU ID
to the hypervisor's notion of CPU ID is not initialized,
we should fall back on the non-enligghtened path for IPI.
A merge error introduced this bug; fix it.

Fixes: 1268ed0c474a ("Merge branch 'x86/urgent' into x86/hyperv")
