Binding ACPI handle to SCSI device has several drawbacks, namely:
1 During ATA device initialization time, ACPI handle will be needed
while SCSI devices are not created yet. So each time ACPI handle is
needed, instead of retrieving the handle by ACPI_HANDLE macro,
a namespace scan is performed to find the handle for the corresponding
ATA device. This is inefficient, and also expose a restriction on
calling path not holding any lock.
2 The binding to SCSI device tree makes code complex, while at the same
time doesn't bring us any benefit. All ACPI handlings are still done
in ATA module, not in SCSI.
Rework the ATA ACPI binding code to bind ACPI handle to ATA transport
devices(ATA port and ATA device). The binding needs to be done only once,
since the ATA transport devices do not go away with hotplug. And due to
this, the flush_work call in hotplug handler for ATA bay is no longer
needed.
Tested on an Intel test platform for binding and runtime power off for
ODD(ZPODD) and hard disk; on an ASUS S400C for binding and normal boot
and S3, where its SATA port node has _SDD and _GTF control methods when
configured as an AHCI controller and its PATA device node has _GTF
control method when configured as an IDE controller. SATA PMP binding
and ATA hotplug is not tested.

We want ppc64 to be able to select between optimised assembly
checksum routines in big endian and the generic lib/checksum.c
routines in little endian.
The lpfc driver is forcing CONFIG_GENERIC_CSUM on which means
we are unable to make the decision to enable it in the arch
Kconfig. If the option exists it is always forced on.
This got introduced in 3.10 via commit 6a7252fdb0c3 ([SCSI] lpfc:
fix up Kconfig dependencies). I spoke to Randy about it and
the original issue was with CRC_T10DIF not being defined.
As such, remove the select of CONFIG_GENERIC_CSUM.

It required some functions to be moved around to place the show and
store functions next to each other, the old order seemed to make no
sense at all.

On some bnx2x devices, iSCSI is determined to be unsupported only after
firmware is downloaded. We need to check max_iscsi_conn again after
NETDEV_UP and block iSCSI init operations. Without this fix, iscsiadm
can hang as the firmware will not respond to the iSCSI init message.

Problem: When Hardware IOMMU is on, megaraid_sas driver initialization fails
in kdump kernel with LSI MegaRAID controller(device id-0x73).
Actually this issue needs fix in firmware, but for firmware running in field,
this driver fix is proposed to resolve the issue. At firmware initialization
time, if firmware does not come to ready state, driver will reset the adapter
and retry for firmware transition to ready state unconditionally(not only
executed for kdump kernel).

Remove HV_DRV_VERSION, it has no meaning for upstream drivers.
Initially it was supposed to show the "Linux Integration Services"
version, now it is not in sync anymore with the out-of-tree drivers
available from the MSFT website.
The only place where a version string is still required is the KVP
command "IntegrationServicesVersion" which is handled by
tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass
the current string to the daemon during KVP userland registration.
