Merge branch 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev
* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: [libata] ata_piix: Enable parallel scan sata_nv: use hardreset only for post-boot probing [libata] ahci: Restore SB600 SATA controller 64 bit DMA ata_piix: Remove stale comment ata_piix: Turn on hotplugging support for older chips ahci: misc cleanups for EM stuff [libata] get rid of ATA_MAX_QUEUE loop in ata_qc_complete_multiple() v2 sata_sil: enable 32-bit PIO sata_sx4: speed up ECC initialization libata-sff: avoid byte swapping in ata_sff_data_xfer() [libata] ahci: use less error-prone array initializers

* The failures are varied but the following patterns seem true for

* all flavors.
|

*
|
||||
* - Softreset during boot always works.
|
||||
*
|
||||
* - Hardreset during boot sometimes fails to bring up the link on

* certain comibnations and device signature acquisition is
|
||||
* unreliable.
|
||||
*
|
||||
* - Hardreset is often necessary after hotplug.
|
||||
*
|
||||
* So, preferring softreset for boot probing and error handling (as
|
||||
* hardreset might bring down the link) but using hardreset for
|
||||
* post-boot probing should work around the above issues in most
|
||||
* cases. Define nv_hardreset() which only kicks in for post-boot
|
||||
* probing and use it for all variants.
