2009-02-05trace: assign defaults at register_ftrace_eventArnaldo Carvalho de Melo
Impact: simplification of tracers As all tracers are doing this we might as well do it in register_ftrace_event and save one branch each time we call these callbacks.

2009-02-04trace: judicious error checking of trace_seq resultsArnaldo Carvalho de Melo
Impact: bugfix and cleanup Some callsites were returning either TRACE_ITER_PARTIAL_LINE if the trace_seq routines (trace_seq_printf, etc) returned 0 meaning its buffer was full, or zero otherwise. But... /* Return values for print_line callback */ enum print_line_t { TRACE_TYPE_PARTIAL_LINE = 0, /* Retry after flushing the seq */ TRACE_TYPE_HANDLED = 1, TRACE_TYPE_UNHANDLED = 2 /* Relay to other output functions */ }; In other cases the return value was not being relayed at all. Most of the time it didn't hurt because the page wasn't get filled, but for correctness sake, handle the return values everywhere.

2009-02-04Blackfin arch: Remove outdated codeMichael Hennerich
The removed version with the loop registers saved on the stack was originally intended to workaround the missing toolchain support for LoopReg Clobbers. Since our toolchain now supports these there is no point in keeping this workaround. And since we don't touch LoopRegs anymore we're no longer subject for ANOMALY_05000312.

2009-02-04Blackfin arch: reset POLAR setting when acquiring a gpio for the first timeMichael Hennerich
when requesting a GPIO for the first time, the POLAR setting is not set to a sane state. this can lead to indeterminate behavior that cannot be resolved without an explicit write to the Blackfin port POLAR register. when requesting a GPIO for the first time via gpio_request(), the POLAR setting for the GPIO in question should be set to sane state. this should occur if the GPIO has not been allocated in any other way. some examples: - when doing something like "request_irq(); gpio_request();" on the same GPIO, the POLAR setting should not be reset. - when doing "gpio_request(); gpio_request();" on the same GPIO, the POLAR setting should be reset only the first time and not the second.
