With the tokens for all implemented RTAS functions now available via rtas_function_token(), which is optimal and safe for arbitrary contexts, there is no need to use rtas_token() or cache its result. Most conversions are trivial, but a few are worth describing in more detail: * Error injection token comparisons for lockdown purposes are consolidated into a simple predicate: token_is_restricted_errinjct(). * A couple of special cases in block_rtas_call() do not use rtas_token() but perform string comparisons against names in the function table. These are converted to compare against token values instead, which is logically equivalent but less expensive. * The lookup for the ibm,os-term token can be deferred until needed, instead of caching it at boot to avoid device tree traversal during panic. * Since rtas_function_token() accesses a read-only data structure without taking any locks, xmon's lookup of set-indicator can be performed as needed instead of cached at startup.
