Hello, all. This is the second take of new-EH-framework patchset. Changes from the last take[L] are... * adjusted to removal of @verbose from reset methods * ata_exec_internal() synchronizes properly while freeing qc * ata_exec_internal() whine and force ATA_ERR_OTHER if the internal qc has failed but neither the interrupt handler nor ->post_internal_cmd sets error code. * SError and IRQ are cleared in ata_std_postreset() to clear error conditions and IRQs which can be raised during reset. * ata_do_reset() now automatically freezes the port before proceeding with reset. So, reset operations are guaranteed to be performed on frozen ports. * ata_port_freeze() and thus ->freeze() method can be called multiple times without being thawed inbetween. ->freeze() must not assume that the port is in thawed state. * ata_scsi_error() retries ->error_handler() if the port is frozen on completion. This is to handle cases where errors occur after ->error_handler() revived the port but before EH finishes. This is done in such a way that EH doesn't miss freezing error condition under any condition. Repeat is limited to 5 times. * EH is inactive until the SCSI host is activated (SHOST_RUNNING). This prevents EH from running simultaneously with initial probing. * various cosmetic changes (comments, new lines, messages...)
