Summary

The SUSE Linux Enterprise 15 SP1 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption.
