Subject: [PATCH] x86/hyperv: LP creation with lp_index on same CPU-id
Date: Mon, 31 May 2021 13:10:46 +0530 [thread overview]
Message-ID: <20210531074046.113452-1-kumarpraveen@linux.microsoft.com> (raw)
The hypervisor expects the lp_index to be same as cpu-id during LP creation
This fix correct the same, as cpu_physical_id can give different cpu-id.
