Subject: [patch 0/3] x86/kvm: Basic split lock #AC handling

This is a reworked version of the patches posted by Sean:

 https://lore.kernel.org/r/20200402155554.27705-1-sean.j.christopherson@intel.com

The changes vs. this are:

    1) Use a separate function for guest split lock handling

    2) Force SIGBUS when SLD mode fatal

    3) Rename the misnomed helper function which decides whether
       #AC is injected into the guest or not and move the feature
       check and the comments into that helper.

Thanks,

	tglx
