0cf4a7d6cf ahci: disable DEVSLP for Intel Valleyview
On Intel Valleyview SoC, SATA device sleep is not reliable. When
DEVSLP is attempted on certain SSDs, port_devslp write would fail
and result in malfunction of AHCI controller. AHCI controller may
be not shown in PCI enumeration after reset. Complete power source
removal may be required to recover from this failure. So we blacklist
this device and override host device reported capabilities such that
device LPM will only attempt slumber but not DEVSLP.

8a4aeec8d2 libata/ahci: accommodate tag ordered controllers
The AHCI spec allows implementations to issue commands in tag order
rather than FIFO order:

	5.3.2.12 P:SelectCmd
	HBA sets pSlotLoc = (pSlotLoc + 1) mod (CAP.NCS + 1)
	or HBA selects the command to issue that has had the
	PxCI bit set to '1' longer than any other command
	pending to be issued.

The result is that commands posted sequentially (time-wise) may play out
of sequence when issued by hardware.

This behavior has likely been hidden by drives that arrange for commands
to complete in issue order.  However, it appears recent drives (two from
different vendors that we have found so far) inflict out-of-order
completions as a matter of course.  So, we need to take care to maintain
ordered submission, otherwise we risk triggering a drive to fall out of
sequential-io automation and back to random-io processing, which incurs
large latency and degrades throughput.

This issue was found in simple benchmarks where QD=2 seq-write
performance was 30-50% *greater* than QD=32 seq-write performance.

Tagging for -stable and making the change globally since it has a low
risk-to-reward ratio.  Also, word is that recent versions of an unnamed
OS also does it this way now.  So, drives in the field are already
experienced with this tag ordering scheme.

2cf532f5e6 ahci: Do not receive interrupts sent by dummy ports
In multiple MSI mode all AHCI ports (including dummy) get assigned
separate MSI vectors and (as result of execution
pci_enable_msi_exact() function) separate IRQ numbers, (mapped to the
MSI vectors).

Therefore, although interrupts from dummy ports are not desired they
are still enabled. We do not request IRQs for dummy ports, but that
only means we do not assign AHCI-specific ISRs to corresponding IRQ
numbers.

As result, dummy port interrupts still could come and traverse all the
way from the PCI device to the kernel, causing unnecessary overhead.

This update disables IRQs for dummy ports and prevents the described
issue.

ab0f9e78b9 ahci: Ensure "MSI Revert to Single Message" mode is not enforced
The AHCI specification allows hardware to choose to revert to
single MSI mode when fewer messages are allocated than requested.
Yet, at least ICH10 chipset reverts to single MSI mode even when
enough messages are allocated in some cases (see below).

This update forces the driver to not rely on initialization of
multiple MSIs mode alone and always check if "MSI Revert to
Single Message" (MRSM) mode was enforced by the controller and
fallback to the single MSI mode in case it did.

That prevents a situation when the driver configured multiple
per-port IRQ handlers, but the controller sends all port's
interrupts to a single IRQ, which could easily screw up the
interrupt handling and lead to delays and possibly crashes.

The fix was tested on a 6-port controller that successfully
reverted to the single MSI mode:

00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA
AHCI Controller (prog-if 01 [AHCI 1.0])
	Subsystem: Super Micro Computer Inc Device 10a7
	Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 101
	I/O ports at f110 [size=8]
	I/O ports at f100 [size=4]
	I/O ports at f0f0 [size=8]
	I/O ports at f0e0 [size=4]
	I/O ports at f020 [size=32]
	Memory at fbf00000 (32-bit, non-prefetchable) [size=2K]

	Capabilities: [70] Power Management version 3
	Capabilities: [a8] SATA HBA v1.0
	Capabilities: [b0] PCI Advanced Features
	Kernel driver in use: ahci

With 6 ports just 8 MSI vectors should be enough, but the adapter
enforces the MRSM mode when less than 16 vectors are written to
the Multiple Messages Enable PCI register. I instigated MRSM mode
by forcing @nvec to 8 in ahci_init_interrupts().

74c03eb630 libata: make AHCI_XGENE depend on PHY_XGENE
AHCI_XGENE is only applicable on ARM64 but it can also be enabled for
compile testing; however, AHCI_XGENE selects PHY_XGENE which has other
arch specific dependencies.  This leads to the following warning when
enabling it on other archs for compile testing.

  warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct
  dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))

Selecting a config option which itself has dependencies can easily
lead to broken configurations.  For now, let's just make AHCI_XGENE
depend on PHY_XGENE which has all the necessary dependencies already.

 "This is the pull request for the core block IO bits for the 3.15
  kernel.  It's a smaller round this time, it contains:

   - Various little blk-mq fixes and additions from Christoph and
     myself.

   - Cleanup of the IPI usage from the block layer, and associated
     helper code.  From Frederic Weisbecker and Jan Kara.

   - Duplicate code cleanup in bio-integrity from Gu Zheng.  This will
     give you a merge conflict, but that should be easy to resolve.

   - blk-mq notify spinlock fix for RT from Mike Galbraith.

   - A blktrace partial accounting bug fix from Roman Pen.

   - Missing REQ_SYNC detection fix for blk-mq from Shaohua Li"

1a0b6abaea SCSI misc on 20140401
This patch consists of the usual driver updates (megaraid_sas, scsi_debug,
 qla2xxx, qla4xxx, lpfc, bnx2fc, be2iscsi, hpsa, ipr) plus an assortment of
 minor fixes and the first precursors of SCSI-MQ (the code path
 simplifications) and the bug fix for the USB oops on remove (which involves an
 infrastructure change, so is sent via the main tree with a delayed backport
 after a cycle in which it is shown to introduce no new bugs).

c70929147a sound updates for 3.15-rc1
There have been lots of changes in ALSA core, HD-audio and ASoC, also
 most of PCI drivers touched by conversions of printks.  All these
 resulted in a high volume and wide ranged patch sets in this release.
 Many changes are fairly trivial, but also lots of nice cleanups and
 refactors.  There are a few new drivers, most notably, the Intel
 Haswell and Baytrail ASoC driver.
 
 Core changes:
 - A bit modernization; embed the device struct into snd_card struct,
   so that it may be referred from the beginning.  A new snd_card_new()
   function is introduced for that, and all drivers have been
   converted.
 
 - Simplification in the device management code in ALSA core;
   now managed by a simple priority list instead
 
 - Converted many kernel messages to use the standard dev_err() & co;
   this would be the pretty visible difference, especially for
   HD-audio.
 
 HD-audio:
 - Conexant codecs use the auto-parser as default now;
   the old static code still remains in case of regressions.
   Some old quirks have been rewritten with the fixups for auto-parser.
 
 - C-Media codecs also use the auto-parser as default now, too.
 
 - A device struct is assigned to each HD-audio codec, and the formerly
   hwdep attributes are accessible over the codec sysfs, too.
   hwdep attributes still remain for compatibility.
 
 - Split the PCI-specific stuff for HD-audio controller into a separate
   module, ane make a helper module for the generic controller driver.
   This is a preliminary change for supporting Tegra HDMI controller in
   near future, which slipped from 3.15 merge.
 
 - Device-specific fixes: mute LED support for Lenovo Ideapad,
   mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
   Dell laptop headset quirks
 
 - Make the HD-audio codec response a bit more robust
 
 - A few improvements on Realtek ALC282 / 283 about the pop noises
 
 - A couple of Intel HDMI fixes
 
 ASoC:
 - Lots of cleanups for enumerations; refactored lots of error prone
   original codes to use more modern APIs
 
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle
 
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues
 
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues
 
 - DPCM support for Intel Haswell and Bay Trail platforms, lots of
   fixes
 
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
 
 - Fixes for the simple-card DAI format DT mess
 
 - DT support for a couple more devices.
 
 - Use of the tdm_slot mapping in a few drivers
 
 Others:
 - Support of reset_resume callback for improved S4 in USB-audio driver;
   the device with boot quirks have been little tested, which we need
   to watch out in this development cycle
 
 - Add PM support for ICE1712 driver (finally!);
   it's still pretty partial support, only for M-Audio devices

c12ac9f98e spi: Updates for v3.15
A busy release for both cleanups and new drivers this time along with
 further factoring out of replicated code into the core:
 
  - Provide support in the core for DMA mapping transfers - essentially
    all drivers weren't implementing this properly, now there's no
    excuse.
  - Dual and quad mode support for spidev.
  - Fix handling of cs_change in the generic implementation.
  - Remove the S3C_DMA code from the s3c64xx driver now that all the
    platforms using it have been converted to dmaengine.
  - Lots of improvements to the Renesas SPI controllers.
  - Drivers for Allwinner A10 and A31, Qualcomm QUP and Xylinx xtfpga.
  - Removal of the bitrotted ti-ssp driver.

3786075b5e regulator: Updates for v3.15
This release has lots and lots of small cleanups and fixes in the
 regulator subsystem, mainly cleaning up some bad patterns that got
 duplicated in DT code, but otherwise very little of note outside
 of the scope of the relevant drivers:
 
  - Support for configuration of the initial state for gpio regulators
    with multi-voltage support.
  - Support for calling regulator_set_voltage() on fixed regulators.
  - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung S2MPA01 &
    S2MPS11/4, some PWM controlled regulators found on some ST boards and
    TI TPS65218.

4dedde7c7a ACPI and power management updates for 3.15-rc1
- Device PM QoS support for latency tolerance constraints on systems with
    hardware interfaces allowing such constraints to be specified.  That is
    necessary to prevent hardware-driven power management from becoming
    overly aggressive on some systems and to prevent power management
    features leading to excessive latencies from being used in some cases.
 
  - Consolidation of the handling of ACPI hotplug notifications for device
    objects.  This causes all device hotplug notifications to go through
    the root notify handler (that was executed for all of them anyway
    before) that propagates them to individual subsystems, if necessary,
    by executing callbacks provided by those subsystems (those callbacks
    are associated with struct acpi_device objects during device
    enumeration).  As a result, the code in question becomes both smaller
    in size and more straightforward and all of those changes should not
    affect users.
 
  - ACPICA update, including fixes related to the handling of _PRT in cases
    when it is broken and the addition of "Windows 2013" to the list of
    supported "features" for _OSI (which is necessary to support systems
    that work incorrectly or don't even boot without it).  Changes from
    Bob Moore and Lv Zheng.
 
  - Consolidation of ACPI _OST handling from Jiang Liu.
 
  - ACPI battery and AC fixes allowing unusual system configurations to
    be handled by that code from Alexander Mezin.

Merge tag 'pm+acpi-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the
     list of supported "features" for _OSI (which is necessary to

Pull irq code updates from Thomas Gleixner:
 "The irq department proudly presents:

   - Another tree wide sweep of irq infrastructure abuse.  Clear winner
     of the trainwreck engineering contest was:
         #include "../../../kernel/irq/settings.h"

   - Tree wide update of irq_set_affinity() callbacks which miss a cpu
     online check when picking a single cpu out of the affinity mask.

   - Tree wide consolidation of interrupt statistics.

   - Updates to the threaded interrupt infrastructure to allow explicit
     wakeup of the interrupt thread and a variant of synchronize_irq()
     which synchronizes only the hard interrupt handler.  Both are
     needed to replace the homebrewn thread handling in the mmc/sdhci
     code.

   - New irq chip callbacks to allow proper support for GPIO based irqs.
     The GPIO based interrupts need to request/release GPIO resources
     from request/free_irq.

   - A few new ARM interrupt chips.  No revolutionary new hardware, just
     differently wreckaged variations of the scheme.

   - Small improvments, cleanups and updates all over the place"

I was hoping that that trainwreck engineering contest was a April Fools'
joke.  But no.

 "There are two memory management related changes, the CMMA support for
  KVM to avoid swap-in of freed pages and the split page table lock for
  the PMD level.  These two come with common code changes in mm/.

  A fix for the long standing theoretical TLB flush problem, this one
  comes with a common code change in kernel/sched/.

  Another set of changes is Heikos uaccess work, included is the initial
  set of patches with more to come.

  And fixes and cleanups as usual"

Pull s390 compat wrapper rework from Heiko Carstens:
 "S390 compat system call wrapper simplification work.

  The intention of this work is to get rid of all hand written assembly
  compat system call wrappers on s390, which perform proper sign or zero
  extension, or pointer conversion of compat system call parameters.
  Instead all of this should be done with C code eg by using Al's
  COMPAT_SYSCALL_DEFINEx() macro.

  Therefore all common code and s390 specific compat system calls have
  been converted to the COMPAT_SYSCALL_DEFINEx() macro.

  In order to generate correct code all compat system calls may only
  have eg compat_ulong_t parameters, but no unsigned long parameters.
  Those patches which change parameter types from unsigned long to
  compat_ulong_t parameters are separate in this series, but shouldn't
  cause any harm.

  The only compat system calls which intentionally have 64 bit
  parameters (preadv64 and pwritev64) in support of the x86/32 ABI
  haven't been changed, but are now only available if an architecture
  defines __ARCH_WANT_COMPAT_SYS_PREADV64/PWRITEV64.

  System calls which do not have a compat variant but still need proper
  zero extension on s390, like eg "long sys_brk(unsigned long brk)" will
  get a proper wrapper function with the new s390 specific
  COMPAT_SYSCALL_WRAPx() macro:

     COMPAT_SYSCALL_WRAP1(brk, unsigned long, brk);

  which generates the following code (simplified):

     asmlinkage long sys_brk(unsigned long brk);
     asmlinkage long compat_sys_brk(long brk)
     {
         return sys_brk((u32)brk);
     }

  Given that the C file which contains all the COMPAT_SYSCALL_WRAP lines
  includes both linux/syscall.h and linux/compat.h, it will generate
  build errors, if the declaration of sys_brk() doesn't match, or if
  there exists a non-matching compat_sys_brk() declaration.

  In addition this will intentionally result in a link error if
  somewhere else a compat_sys_brk() function exists, which probably
  should have been used instead.  Two more BUILD_BUG_ONs make sure the
  size and type of each compat syscall parameter can be handled
  correctly with the s390 specific macros.

  I converted the compat system calls step by step to verify the
  generated code is correct and matches the previous code.  In fact it
  did not always match, however that was always a bug in the hand
  written asm code.

  In result we get less code, less bugs, and much more sanity checking"

Pull x86 LTO changes from Peter Anvin:
 "More infrastructure work in preparation for link-time optimization
  (LTO).  Most of these changes is to make sure symbols accessed from
  assembly code are properly marked as visible so the linker doesn't
  remove them.

  My understanding is that the changes to support LTO are still not
  upstream in binutils, but are on the way there.  This patchset should
  conclude the x86-specific changes, and remaining patches to actually
  enable LTO will be fed through the Kbuild tree (other than keeping up
  with changes to the x86 code base, of course), although not
  necessarily in this merge window"
