There were several places where only enabled devices should be iterated over but device enabledness wasn't checked. * IDENTIFY data 40 wire check in cable_is_40wire() * xfer_mode/ncq_enabled saving in ata_scsi_error() * DUBIOUS_XFER handling in ata_set_mode() While at it, reformat comments in cable_is_40wire().

select TICK_ONESHOT
help
This option enables a tickless system: timer interrupts will
only trigger on an as-needed basis both when the system is
busy and when the system is idle.

This option enables high resolution timer support. If your
hardware is not capable then this option only increases
the size of the kernel image.
