Subject: [PATCH 12/25] x86/MCE/AMD: Define function to get Interleave Address Bit
Date: Fri,  7 May 2021 15:01:27 -0400	[thread overview]
Message-ID: <20210507190140.18854-13-Yazen.Ghannam@amd.com> (raw)
In-Reply-To: <20210507190140.18854-1-Yazen.Ghannam@amd.com>

From: Yazen Ghannam <yazen.ghannam@amd.com>

Move code to find the interleave address bit into a separate helper
function.
