Whereas ARM-based platforms have four phy interface registers and
information, the MIPS-based platforms have only three registers, and
there are no information and documentation. In the original BSP, It
using "strict-ahci" did not control these registers.

The most MIPS-based platforms need to disable NCQ while have the NCQ
capability in HOST_CAP, and several ARM-based platforms (eg. BCM7349A0,
BCM7445A0, BCM7445B0) need to disable too.

Since commit c99cd90d98a98aa1 ("ARM: shmobile: r8a7779: Remove legacy
SoC code"), R-Car SoCs are only supported in generic DT-only ARM
multi-platform builds. The driver doesn't need to match platform
devices by name anymore, hence remove the remaining platform_device_id
entries and platform device support.

The newly added suspend/resume implementation for ahci_mvebu causes
a link error when CONFIG_PM_SLEEP is disabled:
ERROR: "ahci_platform_suspend_host" [drivers/ata/ahci_mvebu.ko] undefined!
ERROR: "ahci_platform_resume_host" [drivers/ata/ahci_mvebu.ko] undefined!
This adds the same #ifdef here that exists in the ahci_platform driver

For high frequency I/O the overhead of threaded interrupts impacts
performance. A quick out-of-the-box test (i.e. no affinity tuning)
shows ~10% random read performance at ~20% less cpu. The cpu wins
appear to be from reduced lock contention.

Some AHCI controllers support per-port MSI-X vectors. At the same time
the Linux AHCI driver needs to support one-off architectures that
implement a single MSI-X vector for all ports. The heuristic for
enabling AHCI ports becomes, in order of preference:
1/ per-port multi-MSI-X
2/ per-port multi-MSI
3/ single MSI
4/ single MSI-X
5/ legacy INTX
This all depends on AHCI implementations with potentially broken MSI-X
requesting less vectors than the number of ports. If this assumption is
violated we will need to start explicitly white-listing AHCI-MSIX
implementations.

Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.
In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags. We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.

When calling ->done before releasing resources we could run into a
race where the SCSI midlayer sends another command and races with
the resources beeing manipulated. For libata this can't currently
happen as synchronization happens at a higher level, but I'd still
like to fix it to future proof libata and to avoid copy & paste
into SCSI drivers where this pattern has led to reproducible crashes.

If the AHCI ports' HPCP or ESP bits are set, the port
should be considered external (e.g. eSATA) and is marked
as removable. Userspace tools like udisks then treat it
like an usb drive.
With this patch applied, when I plug a drive into the esata port,
KDE pops up a window asking what to do with the drives(s), just
like it does for any random USB stick.
Removability is indicated to the upper layers by way of the
SCSI RMB bit, as I haven't found another way to signal
userspace to treat a sata disk like any usb stick.

Currently Freescale QorIQ series SATA is supported by ahci_platform
driver. Some SoC specific settings have been put in uboot. So whether
SATA works or not heavily depends on uboot.
This patch will add a new driver to support QorIQ sata which removes
the dependency on any other boot loader.
Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is
compatible with serial ATA 3.0 and AHCI 1.3 specification.

This reverts commit 5163fb62541e
("ahci: added support for Freescale AHCI sata")
The reverted patch added Freescale QorIQ AHCI sata support to
ahci_platform driver though, but it left SoC specific settings to uboot.
It leads to QorIQ sata heavily depending on uboot. In order to removing
the dependency we first revert the old patch and then will add a new driver
for QorIQ SATA.
Since there are no LS* platforms that have been upstreamed, So
the revert would not break anything exists.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for 4.3 for MIPS. Here's the summary:
Three fixes that didn't make 4.2-stable:
- a -Os build might compile the kernel using the MIPS16 instruction
set but the R2 optimized inline functions in <uapi/asm/swab.h> are
implemented using 32-bit wide instructions which is invalid.
- a build error in pgtable-bits.h for a particular kernel
configuration.
- accessing registers of the CM GCR might have been compiled to use
64 bit accesses but these registers are onl 32 bit wide.
And also a few new bits:
- move the ATH79 GPIO driver to drivers/gpio
- the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
change ATH79 accordingly.
- fix definition of pgprot_writecombine
- add an implementation of dma_map_ops.mmap
- fix alignment of quiet build output for vmlinuz link
- BCM47xx: Use kmemdup rather than duplicating its implementation
- Netlogic: Fix 0x0x prefixes of constants.
- merge Bjorn Helgaas' series to remove most of the weak keywords
from function declarations.
- CP0 and CP1 registers are best considered treated as unsigned
values to avoid large values from becoming negative values.
- improve support for the MIPS GIC timer.
- enable common clock framework for Malta and SEAD3.
- a number of improvments and fixes to dump_tlb().
- document the MIPS TLB dump functionality in Magic SysRq.
- Cavium Octeon CN68XX improvments.
- NetLogic improvments.
- irq: Use access helper irq_data_get_affinity_mask.
- handle MSA unaligned accesses.
- a number of R6-related math-emu fixes.
- support for I6400.
- improvments to MSA support.
- add uprobes support.
- move from deprecated __initcall to arch_initcall.
- remove finish_arch_switch().
- IRQ cleanups by Thomas Gleixner.
- migrate to new 'set-state' interface.
- random small cleanups"

Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
machines, and each machine type provides its own gpio.h. However
only a handful really implement the GPIO API, most just forward
everythings to gpiolib.
The Alchemy machine is notable as it provides a system to allow
implementing the GPIO API at the board level. But it is not used by
any board currently supported, so it can also be removed.
For most machine types we can just remove the custom gpio.h, as well
as the custom wrappers if some exists. Some of the code found in
the wrappers must be moved to the respective GPIO driver.
A few more fixes are need in some drivers as they rely on linux/gpio.h
to provides some machine specific definitions, or used asm/gpio.h
instead of linux/gpio.h for the gpio API.

pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3
irq 17: nobody cared (try booting with the "irqpoll" option)
Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
Asynchronous threads for resume_noirq"). Prior to that, we powered on
the functions in order, so this problem shouldn't happen.
e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
solved the problem for JMicron 361 and 363 devices. With async suspend
disabled, we always power on function 0 before function 1.
Barto then reported the same problem with a JMicron 368 (see comment #57 in
the bugzilla).
Rather than extending the blacklist piecemeal, disable async suspend for
all JMicron multi-function SATA/PATA/AHCI devices.
This quirk could stay in the ahci and pata_jmicron drivers, but it's likely
the problem will occur even if pata_jmicron isn't loaded until after the
suspend/resume. Making it a PCI quirk ensures that we'll preserve the
power-on order even if the drivers aren't loaded.

This patch introduces the use of managed resource function
devm_clk_get instead of clk_get and removes corresponding call
to clk_put in the remove function.
To be compatible with the change various gotos are replaced with
direct returns, and unneeded label is dropped.

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.
Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

Pull libata fixes from Tejun Heo:
"A couple important fixes.
- A block layer change which removed restriction on max transfer size
led to silent data corruption on some devices. A new quirk is
added to restore the old size limit for the reported device. If it
gets reported on more devices, we might have to consider restoring
the restriction for ATA devices by default.
- There finally is a SSD which is confirmed to cause data corruption
on TRIM regardless of which flavor is used. A new quirk is added
and the device is blacklisted
- Other device-specific workarounds"
