This patchset is to introduce TSX suspend load tracking feature and expose it to KVM CPUID for processors which support it. KVM reports this information and guests can make use of it finally.
Detailed information on the instruction and CPUID feature flag can be found in the latest "extensions" manual [1].
Changes since v3: * Remove SERIALIZE part from kvm patch and update commit message
Changes since v2: * Combine the two kvm patches into a single one. * Provide features' overview introduction in kvm patch commit message. * Get the latest kernel patches. * Change definition from TSX_LDTRK to TSXLDTRK for TSX new feature. * Change kernel patches Author to the owner. * Remove SERIALIZE enumeration patch.
