Hello,
This series is against 3.17-rc1. Patches 0-7 have been acked.
Patches 8-13 still need reviews and are resent without changes
except 'lpfc' which concerns latest James comments.

Currently the driver fails to analize MSI-X re-enablement
status on resuming and always assumes the success. This
update checks the MSI-X initialization result and fails
to resume if MSI-Xs re-enablement failed.

Currently the driver falls back to INTx mode when MSI-X
initialization failed. This is a suboptimal behaviour
for chips that also support MSI. This update changes that
behaviour and falls back to MSI mode in case MSI-X mode
initialization failed.

The value of the csr-mask of the SATA PHY clock DTS node has a
wrong value resulting a kernel panic as the clock/reset is not
proper for the PHY of the SATA host controller 1. This patch
fixes the correct csr-mask value of the SATA PHY clock DTS node
for the SATA Host controller 1.
As the 'ok' is
The link down issue in first attempt happens due to 2 H/W errata below:
1. Due to HW errata, during speed negotiation, sometimes controller
is not able to detect ALIGN at GEN3(6Gbps) within 54.6us results in
a timeout. This issue can be recovered by issuing a COMRESET again.
2. Due to HW errata,
This patch set contains a couple of fixes related to APM X-Gene SATA
controller driver.
v2 Change:
1. Drop the Link down retry patch from this patch set.
v4 Change:
1. Drop the patch to fix the csr-mask in dts for PHY clock
node of SATA Host Controller 1.
2. Add the patch to correct
