This series removes the long link debounce delays by default for all adapters, except for those known to require these delays (e.g. ata_piix). The first 2 patches are code cleanup improving the interface of several functions handling delays. Patch 3 removes the long delay in sata_link_resume() and reverses the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY to ATA_LFLAG_DEBOUNCE_DELAY for adapters to request the delay if needed. Patch 4 improves sata_link_debounce() by shortening the link stability test, unless the link has the ATA_LFLAG_DEBOUNCE_DELAY flag set. This series was tested on a machine with 2 AHCI adapters (Intel and Marvell) with a port-multiplier box attached to cover that case too. Comments and lots of testing are welcome !
