Doc Text:	A flaw was found in the Linux Kernel. Wrong spelling in the RTAS function table can cause reverse lookups yo fail and warn 'unexpected failed lookup for token' due to function names being used for resetting TCE tables. Linux kernel errors are possible when lockdep is enabled or the RTAS tracepoints are active, since those paths dereference the result of the lookup.	Story Points:	---
