Cover letter [PATCH 0/5] SEV fixes and performance enhancements
From: Tom Lendacky <[email protected]>
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.
