[PATCH v1 0/3] ppc: LPCR synchronisation fixes


From: Nicholas Piggin
Subject: [PATCH v1 0/3] ppc: LPCR synchronisation fixes
Date: Wed, 26 May 2021 19:16:23 +1000

These incoherencies have been around for a while, but they've started
to get noticed now because recent Linux guests crash when LPCR[AIL] is
not set correctly (scv requires it). This series fixes at least AIL and
DPFD incoherency between KVM and QEMU, and between different vCPUs.

Thanks,
Nick

  spapr: Set LPCR to current AIL mode when starting a new CPU
  target/ppc: Synchronize with KVM's LPCR value when creating a vCPU
