[PATCH v4 02/13] powerpc/rtas: Fall back to linear search on failed token->function lookup

From: Nathan Lynch Enabling any of the powerpc:rtas_* tracepoints at boot is likely to result in an oops on RTAS platforms. For example, booting a QEMU pseries model with 'trace_event=powerpc:rtas_input' in the command line leads to: BUG: Kernel NULL pointer dereference on read at 0x0008
