Pull x86 bugfix from Thomas Gleixner:
"A single bugfix for the recent changes related to registering the boot
cpu when this has not happened before prefill_possible_map().
The main problem with this change got fixed already, but we missed the
case where the local APIC is not yet mapped, when prefill_possible_map()
is invoked, so the registration of the boot cpu which has the APIC bit
set in CPUID will explode.
I should have seen that issue earlier, but all I can do now is feeling
embarassed"

x86/smpboot: Init apic mapping before usage

The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.
The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.
There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().
In hindsight, I should have noticed that combination earlier.
Sorry for the churn (also in stable)!

Commit e96a8a3bb671 ("UBI: Fastmap: Do not add vol if it already
exists") introduced a bug by changing the possible error codes returned
by add_vol():
- this function no longer returns NULL in case of allocation failure
but return ERR_PTR(-ENOMEM)
- when a duplicate entry in the volume RB tree is found it returns
ERR_PTR(-EEXIST) instead of ERR_PTR(-EINVAL)
Fix the tests done on add_vol() return val to match this new behavior.

Pull ARM SoC fixes from Olof Johansson:
"We haven't seen a whole lot of fixes for the first two weeks since the
merge window, but here is the batch that we have at the moment.
Nothing sticks out as particularly bad or scary, it's mostly a handful
of smaller fixes to several platforms. The Uniphier reset controller
changes could probably have been delayed to 4.10, but they're not
scary and just plumbing up driver changes that went in during the

Please don't add these for vcc_sd, and mmc-core/driver will control
it. Otherwise, it will waste energy even without sdmmc in slot.
Moreover, it will causes a bug:
If we insert/remove sd card, we could see
[9.337271] mmc0: new ultra high speed SDR25 SDHC card at address 0007
[9.345144] mmcblk0: mmc0:0007 SD32G 29.3 GiB
This is okay for normal sd insert/remove test, but when I debug some
issues for sdmmc, I did unbind/bind test. And there is a interesting
phenomenon when we bind the driver again:
[58.314069] mmc0: new high speed SDHC card at address 0007
[58.320282] mmcblk0: mmc0:0007 SD32G 29.3 GiB
So the sd card could just support high speed without power cycle
since the vcc_sd is always on, which makes the sd card fail to
reinit its internal ocr mask.

- A couple of patches from Fabio to fix the GPC power domain regression
which is caused by PM Domain core change 0159ec670763dd
("PM / Domains: Verify the PM domain is present when adding a
provider"), and a related kernel crash seen with multi_v7_defconfig
build.
- Correct the PHY ID mask for AR8031 to match phy driver code.
- Apply new added timer erratum A008585 for LS1043A and LS2080A SoC.
- Correct vf610 global timer IRQ flag to avoid warning from gic driver
after commit 992345a58e0c ("irqchip/gic: WARN if setting the
interrupt type for a PPI fails").

The global timer IRQ (PPI[0], PPI 11 in device tree terms) is a
rising edge interrupt. The ARM Cortex-A5 MPCore TRM in Chapter
10.1.2. Interrupt types and sources says:
"Interrupt is rising-edge sensitive."
The bits seem to be read-only, hence this missconfiguration had
no negative effect. However, with commit 992345a58e0c
("irqchip/gic: WARN if setting the interrupt type for a PPI fails")
warnings such as this get printed:
GIC: PPI11 is secure or misconfigured
With this change the new configuration matches the default
configuration and no warning is printed anymore.

Instead of returning of_genpd_add_provider_onecell() directly,
we should check its return value and in the case of error we
should unwind the previously taken actions, which in these case are:
- Call imx6q_pm_pu_power_off()
- Set imx6q_pu_domain.reg back to NULL
Setting imx6q_pu_domain.reg to NULL in the error case is important
as it will prevent further operations in the pu_reg regulator.
This kernel crash is not observed with imx_v6_v7_defconfig because
it selects GPU and VPU drivers, which are consumers of the GPC block
and thus change the refcount of the pu_reg regulator.

Since commit 0159ec670763dd ("PM / Domains: Verify the PM domain is present
when adding a provider") the following regression is observed on imx6:
imx-gpc: probe of 20dc000.gpc failed with error -22
The gpc probe fails because of_genpd_add_provider_onecell() now checks
if all the domains are initialized via pm_genpd_present() function
and it fails because not all the power domains are initialized.
In order to fix this error, initialize all the power domains from
imx_gpc_domains[], not only the imx6q_pu_domain.base one.

I made a mistake as for naming for this block. The MIO block is not
implemented for these 3 SoCs in the first place. The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear

This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):
root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[ 9.960296] mmcblk0: error -110 sending status command, retrying
[ 9.966461] mmcblk0: error -110 sending status command, retrying
[ 9.972534] mmcblk0: error -110 sending status command, aborting
Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.
I don't know if this has ever been correct, sadly. It works after
this patch.

I2C and SPI interfaces share common clock trees within the CP110 HW block.
It occurred that SPI0 interface has wrong clock assignment in the device
tree, which is fixed in this commit to a proper value.

Since the commit bd3677ff31a3 ("clk: mvebu: Remove corediv clock from
Armada XP"), the corediv clk is no more selected for Armada XP, however
this clock is used for Armada XP using the compatible
armada-370-corediv-clock.
While since commit 1594d568c6e3 ("clk: mvebu: Move corediv config to
mvebu config") Armada 38x and Armada 375 got corediv support again, not
only Armada XP was missed but also Armada 39x.
Actually all the SoC selecting MVEBU_V7 config need this clock:
git grep "\-corediv-clock" arch/arm/boot/dts
arch/arm/boot/dts/armada-370-xp.dtsi: compatible = "marvell,armada-370-corediv-clock";
arch/arm/boot/dts/armada-375.dtsi: compatible = "marvell,armada-375-corediv-clock";
arch/arm/boot/dts/armada-38x.dtsi: compatible = "marvell,armada-380-corediv-clock";
arch/arm/boot/dts/armada-39x.dtsi: compatible = "marvell,armada-390-corediv-clock"
This commit now fixes this behavior by letting MVEBU_V7 select
MVEBU_CLK_COREDIV.

This change consists of two changes:
1) If vmci_doorbell_create is called when neither guest nor
host personality as been initialized, vmci_get_context_id
will return VMCI_INVALID_ID. In that case, we should fail
the create call.
2) In doorbell destroy, we assume that vmci_guest_code_active()
has the same return value on create and destroy. That may not
be the case, so we may end up with the wrong refcount.
Instead, destroy should check explicitly whether the doorbell
is in the index table as an indicator of whether the guest
code was active at create time.

When interrupting an application which was allocating DMAable
memory, it was possible, that the DMA memory was deallocated
twice, leading to the error symptoms below.
Thanks to Gerald, who analyzed the problem and provided this
patch.
I agree with his analysis of the problem: ddcb_cmd_fixups() ->
genwqe_alloc_sync_sgl() (fails in f/lpage, but sgl->sgl != NULL
and f/lpage maybe also != NULL) -> ddcb_cmd_cleanup() ->
genwqe_free_sync_sgl() (double free, because sgl->sgl != NULL and
f/lpage maybe also != NULL)
In this scenario we would have exactly the kind of double free that
would explain the WARNING / Bad page state, and as expected it is
caused by broken error handling (cleanup).
Using the Ubuntu git source, tag Ubuntu-4.4.0-33.52, he was able to reproduce
the "Bad page state" issue, and with the patch on top he could not reproduce
it any more.

Update extcon for v4.9-rc3
This patch fixes the following issue:
- Use the extcon_set_state_sync() to notify the changed state
intead of extcon_set_state() in the Qualcomm USB extcon driver.

The driver was changed after submission to use the new style APIs
like extcon_set_state(). Unfortunately, that only sets the state,
and doesn't notify any consumers that the cable state has
changed. Use extcon_set_state_sync() here instead so that we
notify cable consumers of the state change. This fixes USB
host-device role switching on the db8074 platform.

The host keeps sending heartbeat packets independent of the
guest responding to them. Even though we respond to the heartbeat messages at
interrupt level, we can have situations where there maybe multiple heartbeat
messages pending that have not been responded to. For instance this occurs when the
VM is paused and the host continues to send the heartbeat messages.
Address this issue by draining and responding to all
the heartbeat messages that maybe pending.

SEC registers are not accessible when the TXE device is in low power
state, hence the SEC interrupt cannot be processed if device is not
awake.
In some rare cases entrance to low power state (aliveness off) and input
ready bits can be signaled at the same time, resulting in communication
stall as input ready won't be signaled again after waking up. To resolve
this IPC_HHIER_SEC bit in HHISR_REG should not be cleaned if the
interrupt is not processed.

The current state of driver removal is not great.
CONFIG_DEBUG_TEST_DRIVER_REMOVE finds lots of errors. The help text
currently undersells exactly how many errors this option will find. Add
a bit more description to indicate this option shouldn't be turned on
unless you actually want to debug driver removal. The text can be
changed later when more drivers are fixed up.

If you edit a kernfs backed file with vi(1), you see an ugly error

We have noop_fsync() for this, use it.

Pull staging and IIO driver fixes from Greg KH:
"Here are some small staging and iio driver fixes for reported issues
for 4.9-rc3. Nothing major, the "largest" being a lustre fix for a
sysfs file that was obviously wrong, and had never been tested, so it
was moved to debugfs as that is where it belongs. The others are small
bug fixes for reported issues with various staging or iio drivers.
All have been in linux-next for a while with no reported issues"

If the copy_to_user() fails we should unlock and return directly without
updating "cnt". Also the return value should be -EFAULT instead of the
number of bytes remaining.
