Resubmiting with revisions the remainder from the earlier "RTAS maintenance" series[1] for further comments.
Components: * Improved function token lookups, including efficient "reverse" token-to-name mappings. * Static tracepoints for RTAS entry and exit. Changes: * Rebase on current powerpc/next. * Drop unnecessary cast for xa_load() key argument. (Nick Child) * Document RTAS_FN_FLAG_BANNED_FOR_SYSCALL_ON_LE. (Andrew Donnellan) * Skip tracepoints in unsafe contexts (real mode, CPU offline). (Nicholas Piggin) * Convert RTAS tracepoint definitions to unconditional variants (TRACE_EVENT_CONDITION() -> TRACE_EVENT()), dropping a cpu_online() check that duplicates work already done at the call site.
