libata/for-3.10-fixes never got submitted during v3.10 cycle. Merge
it into for-3.11 so that it can be routed together with other changes
scheduled for v3.11.
Three trivial conflicts in drivers/ata/sata_rcar.c. All are caused by
1b20f6a9ad ("sata_rcar: add 'base' local variable to some functions")
conflicting with logic updates in for-3.10-fixes. The offending
commit simply adds local variable @base on functions which
dereferences sata_rcar_priv->base multiple times. The resolutions are
trivial - applying s/priv->base/base/ in the conflicting logic
updates.

Commit 30dcf76acc69 "libata: migrate ACPI code over to new bindings"
mistakenly dropped the code to register hotplug notificaion handler
for ATA port/devices, causing regression for people using ATA bay,
as kernel bug #59871 shows.
Fix this by adding back the hotplug notification handler registration
code. Since this code has to be run once and notification needs to
be installed on every ATA port/devices handle no matter if there is
actual device attached, we can't do this in binding time for ATA
device ACPI handle, as the binding only occurs when a SCSI device is
created, i.e. there is device attached. So introduce the
ata_acpi_hotplug_init() function to loop scan all ATA ACPI handles
and if it is available, install the notificaion handler for it during
ATA init time.
With the ATA ACPI handle binding to SCSI device tree, it is possible
now that when the SCSI hotplug work removes the SCSI device, the ACPI
unbind function will find that the corresponding ACPI device has
already been deleted by dock driver, causing a scaring message like:
[ 128.263966] scsi 4:0:0:0: Oops, 'acpi_handle' corrupt
Fix this by waiting for SCSI hotplug task finish in our notificaion
handler, so that the removal of ACPI device done in ACPI unbind
function triggered by the removal of SCSI device is run earlier when
ACPI device is still available.

There are some SATA controllers which have both devices 0 and 1 but this module
just zeroes out taskfile and sets then ATA_TFLAG_DEVICE (not sure that's needed)
which could lead to a wrong device being selected just before issuing command.
Thus we should call ata_tf_init() which sets up the device register value
properly, like all other users of ata_exec_internal() do...

For some reason, a lot of port-multipliers have issues with softreset.
SIMG [34]7x series port-multipliers have been quite erratic in this
regard. I recall that it was better with some firmware revisions and
the current list of quirks worked fine for a while. I think it got
worse with later firmwares or maybe my test coverage wasn't good
enough. Anyways, HPA is reporting that his 3726 setup suffers SRST
failures and then the PMP gets confused and fails to probe the last
port.
The hope was that we try to stick to the standard as much as possible
and soonish the PMPs and their firmwares will improve in quality, so
the quirk list was kept to minimum. Well, it seems like that's never
gonna happen.
Let's set NO_SRST for all [34]7x PMPs so that whatever remaining
userbase of the device suffer the least. Maybe we should do the same
for 57xx's but unfortunately I don't have any device left to test and
I'm not even sure 57xx's have ever been made widely available, so
let's leave those alone for now.

The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0. If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.
Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.
To reduce overall code bloat, make the changes described above.

The driver's interrupt handling code is too picky in deciding whether it should
handle an interrupt or not which causes completely unneeded spurious interrupts.
Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read
to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't
get cleared by writing to the SATAINTSTAT register in the interrupt mode we use.
Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for
enabled interrupts and we should clear only those interrupts that we have read
as active first time around, because else we have a race and risk clearing an
interrupt that can occur between read and write of the SATAINTSTAT register
and never registering it...

Using ATA_BMDMA_SHT() to intialize 'sata_rcar_sht' was suboptimal as
the R-Car descriptor table transfer counter is 28 bits wide (bit 1 to
bit 28), so that the 'dma_boundary' field of 0xFFFF is just too small,
as well as the 'sg_tablesize' field of 128. Use ATA_BASE_SHT() to
initialize 'sata_rcar_sht' instead and give proper values to the
'dma_boundary' and 'sg_tablesize' fields explicitly.

I've modified sata_rcar_bmdma_fill_sg() to take care of splitting long
scatter/ gather segments due to the descriptor table transfer counter
being only 28 bits wide (bit 1 to bit 28) but that was in vain as even
if 'sata_rcar_sht' specified a correct 'dma_boundary' field, the DMA
and block layers would have split the S/G segments on the necassary
boundaries. Since the driver uses ATA_BMDMA_SHT() to initilaize
'sata_rcar_sht', the boundary is much smaller, only 0xFFFF, so the
code I've added is even more useless, and it's better to just remove
it.

Iff bmdma_setup() has to stop a DMA transfer before starting a new
one, then the STOP bit in the ATAPI_CONTROL1 register will remain set
(it's only cleared when setting the START bit to 1) and then
bmdma_start() method will set both START and STOP bits simultaneously
which should abort the transfer being just started. Avoid that by
explicitly clearing the STOP bit in bmdma_start() method (in this case
it will be ignored on write).

Some device require DMADIR to be enabled, but are not detected as such
by atapi_id_dmadir. One such example is "Asus Serillel 2"
SATA-host-to-PATA-device bridge: the bridge itself requires DMADIR,
even if the bridged device does not.
As atapi_dmadir module parameter can cause problems with some devices
(as per Tejun Heo's memory), enabling it globally may not be possible
depending on the hardware.
This patch adds atapi_dmadir in the form of a "force" horkage value,
allowing global, per-bus and per-device control.

libata honors DMADIR for regular commands, but not for internal commands

Pull ARM SoC late cleanups from Arnd Bergmann:
"These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle. We
normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time we
need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc
cleanup series because of interdependencies with timer drivers now
moved out of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes for
Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10."

This patch restores libata.noacpi support to libata-acpi.c.
There are broken optional control methods for ATA controller devices in the
real world. The libata.noacpi has been used for a long time as a
workaround to deal with issues caused by the broken ASL codes.
1. The "noacpi" option is introduced by the following commit:
commit 11ef697b37e3c85ce1ac21f7711babf1f5b12784
Date: Thu, 28 Sep 2006 11:29:01 -0700
Subject: libata: ACPI and _GTF support
2. The "noacpi" option is renamed to "libata_noacpi" by the following
commit:
commit d7d0dad62a641c156386288a747c1a2f6bb2e42d
Date: Wed, 28 Mar 2007 01:57:37 -0400
Subject: [libata] Disable ACPI by default; fix namespace problems
3. Some of its logics are changed over time - becomes relying on the
"acpi_handle" bound to the ATA devices since this commit:
commit fafbae87db88a73b166d3bc3294d209207f27056
Date: Tue, 15 May 2007 03:28:16 +0900
Subject: libata-acpi: implement ata_acpi_associate()
4. The option is deleted by the following commit:
commit 30dcf76acc695cbd2fa919e294670fe9552e16e7
Date: Mon, 25 Jun 2012 16:13:04 +0800
Subject: libata: migrate ACPI code over to new bindings
But the libata.noacpi setup is still left in the kernel without codes to
implement it. So the deletion introduces a regression to the Linux.
This patch disables ATA_ACPI support at runtime by stopping acpi binding
on the ATA devices to fix this regression.
This patch is tested by booting a SATA x86-64 kernel or a PATA x86 kernel
with or without "libata.noacpi=1" kernel command line argument.

Since commit 30dcf76acc, ata_ap_acpi_handle will always do a namespace
walk, which requires acquiring an acpi namespace mutex. This made it
impossible to be used when calling path has held a spinlock.
For example, it can occur in the following code path for pata_acpi:
ata_scsi_queuecmd (ap->lock is acquired)
__ata_scsi_queuecmd
ata_scsi_translate
ata_qc_issue
pacpi_qc_issue
ata_acpi_stm
ata_ap_acpi_handle
acpi_get_child
acpi_walk_namespace
acpi_ut_acquire_mutex (acquire mutex while holding lock)
This caused scheduling while atomic bug, as reported in bug #56781.
Actually, ata_ap_acpi_handle doesn't have to walk the namespace every
time it is called, it can simply return the bound acpi handle on the
corresponding SCSI host. The reason previously it is not done this way
is, ata_ap_acpi_handle is used in the binding function
ata_acpi_bind_host by ata_acpi_gtm when the handle is not bound to the
SCSI host yet. Since we already have the ATA port's handle in its
binding function, we can simply use it instead of calling
ata_ap_acpi_handle there. So introduce a new function __ata_acpi_gtm,
where it will receive an acpi handle param in addition to the ATA port
which is solely used for debug statement. With this change, we can make
ata_ap_acpi_handle simply return the bound handle for SCSI host instead
of walking the acpi namespace now.

This is a series originally prepared for inclusion in 3.9, which did
not work out because of dependencies on the dmaengine driver. All the
changes for the dmaengine code are merged in 3.9 now, so we can finally
do the switchover and remove the now unnecessary dma definitions for
spear13xx from the platform code.
The dma platform_data actually made up the majority of the spear13xx
platform code overall, so moving that into device tree files makes the
code substantially smaller.
* spear/dwdma:
ata: arasan: remove the need for platform_data

This adds a complete DT binding for the arasan device driver. There is
currently only one user, which is the spear13xx platform, so we don't
actually have to parse all the properties until another user comes in,
but this does use the generic DMA binding to find the DMA channel.
The patch is untested so far and is part of a series to convert
the spear platform over to use the generic DMA binding, so it
should stay with the rest of the series.
