From 9ce09870e721efacc41fa7ee684e9e299f120350 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Tue, 3 Jan 2023 16:02:44 +0100 Subject: [PATCH] OvmfPkg/SmmCpuFeaturesLib: drop obsolete API implementation Commit 0426115b6738 ("UefiCpuPkg: Remove unused API in SmmCpuFeaturesLib.h", 2022-12-21) removed the declaration of the function SmmCpuFeaturesAllocatePageTableMemory() from the "SmmCpuFeaturesLib.h" library class header. Remove the API's (null-)implementation from OvmfPkg/SmmCpuFeaturesLib as well. Testing: OVMF builds, boots, and suspends/resumes (see earlier in this series).
