Subject: [PATCH v3 0/2] Expose new features for Intel processor

This patchset is to expose two new features, SERIALIZE and
TSX suspend load tracking to KVM CPUID for processors which 
support them. KVM reports this information and guest can 
make use of them finally.

Detailed information on the instructions and CPUID feature
flags can be found in the latest "extensions" manual [1].

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.
