* * * This series of VMCI linux upstreaming patches include latest udpate from VMware to address Greg's and all other's code review comments. Summary of changes: - Rebase our linux kernel tree from v3.5 to v3.7. - Fix all checkpatch warnings and errors. Fix some checkpatch with -strict errors. This addresses Greg's comment: On 15 Nov 2012
