Linus Torvalds 13b6931c44 - A segmented Reverse Map table (RMP) is a across-nodes distributed
table of sorts which contains per-node descriptors of each node-local
   4K page, denoting its ownership (hypervisor, guest, etc) in the realm
   of confidential computing.  Add support for such a table in order to
   improve referential locality when accessing or modifying RMP table
   entries
 
 - Add support for reading the TSC in SNP guests by removing any
   interference or influence the hypervisor might have, with the goal of
   making a confidential guest even more independent from the hypervisor
