[PATCH 0/5] SEV fixes and performance enhancements

[Lendacky, Thomas]

From: Tom Lendacky <thomas.lendacky@xxxxxxx>

This patch series provides fixes in the area of ASID assignment and VM
deactivation.

Additionally, it provides some performance enhancements by reducing the
number of WBINVD/DF_FLUSH invocations that are made.

Note: The third patch in the series modifies a file that is outside of
      the arch/x86/kvm directory.
