https://github.com/ctrliq/kernel-src-tree/pull/37

Upgrade/Update Process (This kernel CentOS base for 4.18.0-553)

• Kernel History Rebuild Process for all src.rpms hosted by RESF
• Create sig-cloud-8/4.18.0-553.33.1.el8_10 branch
• Check if any maintained code is included in the new el release.
• Cherry-pick all code from previous branch into new branch (skipping unneeded code)
  • Fix conflicts as they arise
• Check for any new bug fixes upstream for carried patches
• Build and Test

Removed Patches

• None

New Patches from last Sig/Cloud Update

• x86/cpu: Allow reducing x86_phys_bits during early_identify_cpu()
• x86/cpu: Get rid of an unnecessary local variable in get_cpu_address_sizes()
• x86/cpu: Provide default cache line size if not enumerated
