0976c946a6 arm/versatile: Fix versatile irq specifications.
Two of the versatile irq definitions are incorrect, mostly because two
devices have connections to more than one interrupt controller. Fix them
by using the new interrupts-extended property to fan out without using
an awful interrupt-map nexus node.

79d9701559 of/irq: create interrupts-extended property
The standard interrupts property in device tree can only handle
interrupts coming from a single interrupt parent. If a device is wired
to multiple interrupt controllers, then it needs to be attached to a
node with an interrupt-map property to demux the interrupt specifiers
which is confusing. It would be a lot easier if there was a form of the
interrupts property that allows for a separate interrupt phandle for
each interrupt specifier.

This patch does exactly that by creating a new interrupts-extended
property which reuses the phandle+arguments pattern used by GPIOs and
other core bindings.

0d74578b7d ARM: sunxi: remove .init_time hooks
The machine entries were split up, but the cleanup to remove .init_time
removed the function that the new/split entries refer to. Remove them
since they are no longer needed.

9c0ebcf78f cpufreq: Implement light weight ->target_index() routine
Currently, the prototype of cpufreq_drivers target routines is:

int target(struct cpufreq_policy *policy, unsigned int target_freq,
		unsigned int relation);

And most of the drivers call cpufreq_frequency_table_target() to get a valid
index of their frequency table which is closest to the target_freq. And they
don't use target_freq and relation after that.

So, it makes sense to just do this work in cpufreq core before calling
cpufreq_frequency_table_target() and simply pass index instead. But this can be
done only with drivers which expose their frequency table with cpufreq core. For
others we need to stick with the old prototype of target() until those drivers
are converted to expose frequency tables.

This patch implements the new light weight prototype for target_index() routine.
It looks like this:

int target_index(struct cpufreq_policy *policy, unsigned int index);

CPUFreq core will call cpufreq_frequency_table_target() before calling this
routine and pass index to it. Because CPUFreq core now requires to call routines
present in freq_table.c CONFIG_CPU_FREQ_TABLE must be enabled all the time.

This also marks target() interface as deprecated. So, that new drivers avoid
using it. And Documentation is updated accordingly.

It also converts existing .target() to newly defined light weight
.target_index() routine for many driver.

There's really only one bugfix in this branch, which is a fix for timers on
 the integrator platform. Since Linus Walleij is resurrecting support for

 The rest are a handful of maintainers updates. If you prefer to hold those
 until 3.13 then just merge the first patch on the branch which is the fix.

0c02c8007e of/irq: Rename of_irq_map_* functions to of_irq_parse_*
The OF irq handling code has been overloading the term 'map' to refer to
both parsing the data in the device tree and mapping it to the internal
linux irq system. This is probably because the device tree does have the
concept of an 'interrupt-map' function for translating interrupt
references from one node to another, but 'map' is still confusing when
the primary purpose of some of the functions are to parse the DT data.

This patch renames all the of_irq_map_* functions to of_irq_parse_*
which makes it clear that there is a difference between the parsing
phase and the mapping phase. Kernel code can make use of just the
parsing or just the mapping support as needed by the subsystem.

The patch was generated mechanically with a handful of sed commands.

 "Sorry I let so much accumulate, I was in Buffalo and wanted a few
  things to cook in my tree for a while before sending to you.  Anyways,
  it's a lot of little things as usual at this stage in the game"

 1) Make bonding MAINTAINERS entry reflect reality, from Andy
    Gospodarek.

 2) Fix accidental sock_put() on timewait mini sockets, from Eric
    Dumazet.

 3) Fix crashes in l2tp due to mis-handling of ipv4 mapped ipv6
    addresses, from François CACHEREUL.

 4) Fix heap overflow in __audit_sockaddr(), from the eagle eyed Dan
    Carpenter.

 5) tcp_shifted_skb() doesn't take handle FINs properly, from Eric
    Dumazet.

 6) SFC driver bug fixes from Ben Hutchings.

 7) Fix TX packet scheduling wedge after channel change in ath9k driver,
    from Felix Fietkau.

 8) Fix user after free in BPF JIT code, from Alexei Starovoitov.

 9) Source address selection test is reversed in
    __ip_route_output_key(), fix from Jiri Benc.

10) VLAN and CAN layer mis-size netlink attributes, from Marc
    Kleine-Budde.

11) Fix permission checks in sysctls to use current_euid() instead of
    current_uid().  From Eric W Biederman.

12) IPSEC policies can go away while a timer is still pending for them,
    add appropriate ref-counting to fix, from Steffen Klassert.

13) Fix mis-programming of FDR and RMCR registers on R8A7740 sh_eth
    chips, from Nguyen Hong Ky and Simon Horman.

14) MLX4 forgets to DMA unmap pages on RX, fix from Amir Vadai.

15) IPV6 GRE tunnel MTU upper limit is miscalculated, from Oussama
    Ghorbel.

16) Fix typo in fq_change(), we were assigning "initial quantum" to
    "quantum".  From Eric Dumazet.

17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise
    FQ packet scheduler does not pace those flows properly.  Also from
    Eric Dumazet.

18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland.

19) l2tp_xmit_skb() can be called from process context, not just softirq
    context, so we must always make sure to BH disable around it.  From
    Eric Dumazet.

20) On qdisc reset, we forget to purge the RB tree of SKBs in netem
    packet scheduler.  From Stephen Hemminger.

21) Fix info leak in farsync WAN driver ioctl() handler, from Dan
    Carpenter and Salva Peiró.

    disable the csum offload when IPSEC transformations have been
    applied.  From Fan Du and Vlad Yasevich.

24) Tail loss probing in TCP leaves the socket in the wrong congestion
    avoidance state.  From Yuchung Cheng.

25) In CPSW driver, enable NAPI before interrupts are turned on, from
    Markus Pargmann.

26) Integer underflow and dual-assignment in YAM hamradio driver, from
    Dan Carpenter.

27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must
    unclone it.  This fixes various hard to track down crashes in
    drivers where the SKBs ->gso_segs was changing right from underneath
    the driver during TX queueing.  From Eric Dumazet.

28) Fix the handling of VLAN IDs, and in particular the special IDs 0
    and 4095, in the bridging layer.  From Toshiaki Makita.

29) Another info leak, this time in wanxl WAN driver, from Salva Peiró.

30) Fix race in socket credential passing, from Daniel Borkmann.

31) WHen NETLABEL is disabled, we don't validate CIPSO packets properly,
    from Seif Mazareeb.

    Fragmentation Offload output paths, from Jiri Pirko.

33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel
    Elior.

34) When we removed the explicit neighbour pointer from ipv6 routes a
    slight regression was introduced for users such as IPVS, xt_TEE, and
    raw sockets.  We mix up the users requested destination address with
    the routes assigned nexthop/gateway.  From Julian Anastasov and
    Simon Horman.

35) Fix stack overruns in rt6_probe(), the issue is that can end up
    doing two full packet xmit paths at the same time when emitting
    neighbour discovery messages.  From Hannes Frederic Sowa.

36) davinci_emac driver doesn't handle IFF_ALLMULTI correctly, from
    Mariusz Ceier.

37) Make sure to set TCP sk_pacing_rate after the first legitimate RTT
    sample, from Neal Cardwell.

38) Wrong netlink attribute passed to xfrm_replay_verify_len(), from
    Steffen Klassert.

Currently, on OMAP5, i2c1 and i2c5 defer probe due to pinctrl
dependencies. This changes the i2c ID each bus is registered with in
i2c-dev interface. As a result of this, many userspace tools break and
there is no consistent manner to fix the same if the i2c dev interface
have no consistent numbering.

Since this could happen for other OMAP derivatives, provide i2c alias
for all OMAP3+ SoCs to allow ordering the i2c devices correctly.

59fd3033b5 ARM: fix build errors caused by selection of errata 798181
Several configurations are selecting errata 798181 without SMP
being selected.  This causes a warning from Kconfig:

warning: (ARCH_HIGHBANK && ARCH_KEYSTONE && SOC_OMAP5 && ARCH_TEGRA_114_SOC) selects ARM_ERRATA_798181 which has unmet direct dependencies (CPU_V7 && SMP)

The dependencies are compile time dependencies; select violates these,
resulting in:

psci.c:(.init.text+0x808): undefined reference to `erratum_a15_798181_init'

d48866fefd ARM: imx: ensure dsm_request signal is not asserted when setting LPM
There is a defect in imx6 LPM design.  When SW tries to enter low power
mode with following sequence, the chip will enter low power mode before
A9 CPU execute WFI instruction:

1. Set CCM_CLPCR[1:0] to 2'b00;
2. ARM CPU enters WFI;
3. ARM CPU wakeup from an interrupt event, which is masked by GPC or not
   visible to GPC, such as interrupt from local timer;
4. Set CCM_CLPCR[1:0] to 2'b01 or 2'b10;
5. ARM CPU execute WFI.

Before the last step, the chip will enter WAIT mode if CCM_CLPCR[1:0] is
set to 2'b01, or enter STOP mode if CCM_CLPCR[1:0] is set to 2'b10.

The patch implements a recommended workaround for this issue.

1. SW triggers irq #32(IOMUX) to be always pending manually by setting
   IOMUX_GPR1_GINT bit;
2. SW should then unmask it in GPC before setting CCM LPM;
3. SW should mask it right after CCM LPM is set (bit0-1 of CCM_CLPCR).

1d674a73c5 ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter()
The WB and RBC configuration calls are currently made from
imx6q_set_lpm() for WAIT_CLOCKED and WAIT_UNCLOCKED mode with a simple
state tracking.  This becomes unnecessary since we can make the calls
from imx6q_pm_enter() directly now for suspend.

More importantly, the current call of imx6q_enable_wb() from
imx6q_set_lpm() is buggy.  The CLPCR register bits configured by
imx6q_enable_wb() will get lost, because imx6q_set_lpm() caches the same
register and write it back at the end of the function.  That's why the
imx6dl suspend/resume does not work currently - the wakeup from suspend
triggers a reset on imx6dl.

Moves the WB and RBC calls into imx6q_pm_enter() to save the state
tracking and fixes above bug, so that suspend/resume can start working
on imx6dl.

The imx6q_restart() works fine with normal reboot but will run into
problem with emergency reboot like sysrq-b.  In that case, of_iomap()
gets called from interrupt context and hence triggers the BUG_ON in
__get_vm_area_node().

Actually, since commit c1e31d1 (ARM: imx: create
mxc_arch_reset_init_dt() for DT boot), imx6q/dl should try to use
mxc_restart() by calling mxc_arch_reset_init_dt() beforehand, where
things like of_iomap() can be done.

The patch updates mxc_restart() a little bit to get it work for imx6q/dl
and kill imx6q_restart() completely.

da2f5f4852 ARM: S3C24XX: Fix possible dma selection warning
Currently the s3c sound support selects CONFIG_S3C2410_DMA on s3c24xx
architectures while the generic dma config is enabled by CONFIG_S3C24XX_DMA.

With the way the Kconfig options are layed out currently it is possible
to enable Samsung sound support without enabling the necessary dma support
resulting in warnings like
  warning: (SND_SOC_SAMSUNG && SND_S3C24XX_I2S && SND_S3C2412_SOC_I2S &&
       SND_SOC_SAMSUNG_SMDK2443_WM9710 && SND_SOC_SAMSUNG_LN2440SBC_ALC650)

       S3C24XX_DMA && (CPU_S3C2410 || CPU_S3C2442))

Therefore bring the s3c2410 dma support in line with the way the other
s3c24xx SoCs handle this by having the SoC dma-support selected if the generic
s3c dma support is enabled and have the sound support depend on S3C24XX_DMA
on these arches. The s3c2442 is using the same dma descriptors and therefore
also selected S3C2410_DMA.

a1af347448 ARM: tlb: ASID macro should give 32bit result for BE correct operation
In order for ASID macro to be used as expression passed to
inline asm as 'r' operand it needs to give 32 bit unsigned result,
not unsigned 64bit expression.

Otherwise when 64bit ASID is passed to inline assembler statement
as 'r' operand (32bit) compiler behavior is not well specified.
For example when __flush_tlb_mm function compiled in big endian
case, and ASID is passed to tlb_op macro directly, 0 will be passed
as 'mcr	15, 0, r4, cr8, cr3, {2}' argument in r4, unless ASID

92e94fe1cd ARM: tegra: re-calculate the LP1 data for Tegra30/114
This patch re-calculates the LP1 data of tegra30/114_sdram_pad_address
to base on its label not rely on others. This can make easier to
maintain if some other Tegra chips keep re-using these codes in the
future. And change the name of tegra30_sdram_pad_save to
tegra_sdram_pad_save to make it more common to other chips.

Because the CPU0 was the first up and the last down core when cluster
power up/down or platform suspend. So only CPU0 needs the rest of the
functions to reset flow controller and re-enable SCU and L2. We also
move the L2 init function for Cortex-A15 to there. The secondery CPU

abcba009e5 Changes needed for am43xx for the hwmod data.
This will be the last new set of hwmod data for any SoC
 as future SoCs will use a driver and device tree based
 approach. But before that can be dealt with, we need to
 first sort out the pending driver/clk issues.
 
 Queued by Paul Walmsley <paul@pwsan.com>:
 
 Add hwmod and PRCM data for the TI AM43xx family of SoCs.
 
 Under normal circumstances, these patches would not be merged.
 The hwmod and PRCM data should be moved out either to DT data or
 to drivers/.  Also, the current implementation trades off lines
 of diff by dynamically rewriting static data at runtime, which is
 a bad practice - it causes future maintenance headaches.
 However, after speaking with my upstream, it sounds like it's
 better to merge these patches in their current state, due to long
 term considerations.
 
 Basic test logs are here:
 
 http://www.pwsan.com/omap/testlogs/am43xx_support_v3.13/20131015213706/
 
 Due to the lack of an AM43xx board and any available public
 documentation, it's impossible for me to review or test that
 platform in any meaningful way.  But at least the tests above
 verify that the patches don't affect existing platforms -
 particularly AM33xx.

Support transparent huge pages in KVM/ARM and KVM/ARM64.  The
transparent_hugepage_adjust is not very pretty, but this is also how
it's solved on x86 and seems to be simply an artifact on how THPs
behave.  This should eventually be shared across architectures if
possible, but that can always be changed down the road.

ad361f093c KVM: ARM: Support hugetlbfs backed huge pages
Support huge pages in KVM/ARM and KVM/ARM64.  The pud_huge checking on
the unmap path may feel a bit silly as the pud_huge check is always
defined to false, but the compiler should be smart about this.

Note: This deals only with VMAs marked as huge which are allocated by
users through hugetlbfs only.  Transparent huge pages can only be
detected by looking at the underlying pages (or the page tables
themselves) and this patch so far simply maps these on a page-by-page
level in the Stage-2 page tables.

c8b11de040 iio: at91: introduce touch screen support in iio adc driver
AT91 ADC hardware integrate touch screen support. So this patch add touch
screen support for at91 adc iio driver.
To enable touch screen support in adc, you need to add the dt parameters:
  1. which type of touch are used? (4 or 5 wires), sample period time.
  2. correct pressure detect threshold value.

In the meantime, since touch screen will use a interal period trigger of adc,
so it is conflict to other hardware triggers. Driver will disable the hardware
trigger support if touch screen is enabled.

This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.

58d5ec8f8e ARM: KVM: Yield CPU when vcpu executes a WFE
On an (even slightly) oversubscribed system, spinlocks are quickly
becoming a bottleneck, as some vcpus are spinning, waiting for a
lock to be released, while the vcpu holding the lock may not be
running at all.

This creates contention, and the observed slowdown is 40x for
hackbench. No, this isn't a typo.

The solution is to trap blocking WFEs and tell KVM that we're
now spinning. This ensures that other vpus will get a scheduling
boost, allowing the lock to be released more quickly. Also, using
CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT slightly improves the performance
when the VM is severely overcommited.

Quick test to estimate the performance: hackbench 1 process 1000

2xA15 host (baseline):	1.843s

2xA15 guest w/o patch:	2.083s
4xA15 guest w/o patch:	80.212s
8xA15 guest w/o patch:	Could not be bothered to find out

2xA15 guest w/ patch:	2.102s
4xA15 guest w/ patch:	3.205s
8xA15 guest w/ patch:	6.887s

So we go from a 40x degradation to 1.5x in the 2x overcommit case,
which is vaguely more acceptable.

811e7c8734 Add hwmod and PRCM data for the TI AM43xx family of SoCs.
Under normal circumstances, these patches would not be merged.
 The hwmod and PRCM data should be moved out either to DT data or
 to drivers/.  Also, the current implementation trades off lines
 of diff by dynamically rewriting static data at runtime, which is
 a bad practice - it causes future maintenance headaches.
 However, after speaking with my upstream, it sounds like it's
 better to merge these patches in their current state, due to long
 term considerations.
 
 Basic test logs are here:
 
 http://www.pwsan.com/omap/testlogs/am43xx_support_v3.13/20131015213706/
 
 Due to the lack of an AM43xx board and any available public
 documentation, it's impossible for me to review or test that
 platform in any meaningful way.  But at least the tests above
 verify that the patches don't affect existing platforms -
 particularly AM33xx.

5ad945ea58 ARM: at91: cpuidle: Convert to platform driver
Using the platform driver model is a good way to separate the cpuidle specific
code from the low level pm code. It allows to remove the dependency between
these two components.

The platform_device is located in the pm code and a 'set' function has been
added to set the standby function from the AT91_SOC_START initialization
function. Each SoC with a cpuidle driver will set the standby function in the
platform_data field at init time. Then pm code will register the cpuidle
platform device.

The cpuidle driver will register the platform_driver and use the device's
platform_data as a standby callback in the idle path.

The at91_pm_enter function contains a { if then else } based on cpu_is_xx
similar to what was in cpuidle. This is considered dangerous when adding a new
SoC. Like the cpuidle driver, a standby ops is defined and assigned when the
SoC init function specifies what is its standby function and reused in the
at91_pm_enter's 'case' block.

- several optional peripheral definitions which will be included by sama5d3
  specific SoCs (sama5d3_'periph name'.dtsi)
- sama5d3 specific SoC definitions (sama5d3x.dtsi)

This provides a better representation of the real hardware (drop unneed
