The value for LPI TW timer has to be updated to 0x1E that is the hardcoded value
of 20.5us and it will apply to all EEE enabled Remote PHYs.
Disadvantage is for PHY's that support lesser wakeup time but we can accept it
waiting to implement LLDP to negotiate the Wakeup time of Remote PHY.

"Various assorted fixes:
- a couple of patches from Mark Rutland to resolve an errata with
Cortex-A15 CPUs.
- fix cpuidle for the CPU part ID changes in the last merge window
- add support for a relocation which ARM binutils is generating in
some circumstances"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8130/1: cpuidle/cpuidle-big_little: fix reading cpu id part number
ARM: 8129/1: errata: work around Cortex-A15 erratum 830321 using dummy strex
ARM: 8128/1: abort: don't clear the exclusive monitors
ARM: 8127/1: module: add support for R_ARM_TARGET1 relocations
Here's the weekly batch of fixes from arm-soc.
The delta is a largeish negative delta, due to revert of SMP support for Broadcom's
STB SoC -- it was accidentally merged before some issues had been addressed, so they
will make a new attempt for 3.18. I didn't see a need for a full revert of the whole
platform due to this, we're keeping the rest enabled.
The rest is mostly:
* A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
* Some MTD/NAND fixes for OMAP
* Minor DT fixes for shmobile
* Warning fix for UP builds on vexpress/spc
There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
so it can boot. Drivers and the rest had landed for 3.17, and it's small
and isolated so it made sense to pick up now even if it's not a bugfix.

Enabling DMA_API_DEBUG, warnings are reported at runtime
because the device driver frees DMA memory with wrong functions
and it does not call dma_mapping_error after mapping dma memory.
The first problem is fixed by of introducing a flag that helps us
keeping track which mapping technique was used, so that we can use
the right API for unmap.
This approach was inspired by the e1000 driver, which uses a similar
technique.

The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).
The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.
If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.
Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

This patch is to w/a a problem that happens on some boxes when run at 10Mbps
Half duplex mode.
During the transmission the CSR signal is asserted for some time and the frames
aborted because of carrier sense error.
This is reported by MMC HW counter: txcarrier signal.
This actually is a false carrier so the frames are good and there is no reason
to ask for dropping them.
This patch so disables the Carrier Sense During Transmission
and this means that the MAC transmitter ignore the CRS signal
during frame transmission in Half-Duplex mode.

Pull block layer fixes from Jens Axboe:
"A smaller collection of fixes that have come up since the initial
merge window pull request. This contains:
- error handling cleanup and support for larger than 16 byte cdbs in
sg_io() from Christoph. The latter just matches what bsg and
friends support, sg_io() got left out in the merge.
- an option for brd to expose partitions in /proc/partitions. They
are hidden by default for compat reasons. From Dmitry Monakhov.
- a few blk-mq fixes from me - killing a dead/unused flag, fix for
merging happening even if turned off, and correction of a few
comments.
- removal of unnecessary ->owner setting in systemace. From Michal
Simek.
- two related fixes for a problem with nesting freezing of queues in
blk-mq. One from Ming Lei removing an unecessary freeze operation,
and another from Tejun fixing the nesting regression introduced in
the merge window.
- fix for a BUG_ON() at bio_endio time when protection info is
attached and the IO has an error. From Sagi Grimberg.
- two scsi_ioctl bug fixes for regressions with scsi-mq from Tony
Battersby.
- a cfq weight update fix and subsequent comment update from Toshiaki
Makita"

Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins.
We need to keep IRQ assignment for PCI devices during runtime power
management, otherwise it may cause failure of device wakeups.
Commit 3eec595235 "x86, irq, PCI: Keep IRQ assignment for PCI
devices during suspend/hibernation" has fixed the issue for suspend/
hibernation, we also need the same fix for runtime device sleep too.

If our client is requesting a clock that is above the maximum clock
then the following division will result in 0:
rs->max_freq / rs->speed
We'll then program 0 into the SPI_BAUDR register. The Rockchip TRM
says: "If the value is 0, the serial output clock (sclk_out) is
disabled."
It's much better to end up with the fastest possible clock rather than
a clock that is off, so enforce a minimum value.

The DM crypt target accesses memory beyond allocated space resulting in
a crash on 32 bit x86 systems.
This bug is very old (it dates back to 2.6.25 commit 3a7f6c990a "dm
crypt: use async crypto"). However, this bug was masked by the fact
that kmalloc rounds the size up to the next power of two. This bug
wasn't exposed until 3.17-rc1 commit 298a9fa08a ("dm crypt: use per-bio
data"). By switching to using per-bio data there was no longer any
padding beyond the end of a dm-crypt allocated memory block.
To minimize allocation overhead dm-crypt puts several structures into one
block allocated with kmalloc. The block holds struct ablkcipher_request,
cipher-specific scratch pad (crypto_ablkcipher_reqsize(any_tfm(cc))),
struct dm_crypt_request and an initialization vector.
The variable dmreq_start is set to offset of struct dm_crypt_request
within this memory block. dm-crypt allocates the block with this size:
cc->dmreq_start + sizeof(struct dm_crypt_request) + cc->iv_size.
When accessing the initialization vector, dm-crypt uses the function
iv_of_dmreq, which performs this calculation: ALIGN((unsigned long)(dmreq
+ 1), crypto_ablkcipher_alignmask(any_tfm(cc)) + 1).
dm-crypt allocated "cc->iv_size" bytes beyond the end of dm_crypt_request
structure. However, when dm-crypt accesses the initialization vector, it
takes a pointer to the end of dm_crypt_request, aligns it, and then uses
it as the initialization vector. If the end of dm_crypt_request is not
aligned on a crypto_ablkcipher_alignmask(any_tfm(cc)) boundary the
alignment causes the initialization vector to point beyond the allocated
space.
Fix this bug by calculating the variable iv_size_padding and adding it
to the allocated size.
Also correct the alignment of dm_crypt_request. struct dm_crypt_request
is specific to dm-crypt (it isn't used by the crypto subsystem at all),
so it is aligned on __alignof__(struct dm_crypt_request).
Also align per_bio_data_size on ARCH_KMALLOC_MINALIGN, so that it is
aligned as if the block was allocated with kmalloc.

Commit 43fef47f94 (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.
This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678ab6 (ARM: dts:
Revert enabling of twl configuration for n900).
Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.
This allows us to enable the PMIC configuration for n900.

I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his
"Lenovo Yoga 2 13", and that this patch causes a regression for him.
Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.
Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.

The __init annotations for the DMI callback functions are wrong as this
code can be called even after the module has been initialized, e.g. like
this:
# echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove
# modprobe i915
# echo 1 > /sys/bus/pci/rescan
The first command will remove the PCI device from the kernel's device
list so the second command won't see it right away. But as it registers
a PCI driver it'll see it on the third command. If the system happens to
match one of the DMI table entries we'll try to call a function in long
released memory and generate an Oops, at best.
Fix this by removing the bogus annotation.
Modpost should have caught that one but it ignores section reference
mismatches from the .rodata section. :/

Kinda unexpected, but DIV_ROUND_UP() can overflow if passed an argument
bigger than UINT_MAX - DIVISOR. Fix this by testing for "!cpp" before
using it in the following division.
Note that DIV_ROUND_UP() is defined as:
#define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d))
..this will obviously overflow if (n + d - 1) is bigger than UINT_MAX.

If we assign a Radeon device to a virtual machine, we can no longer
assume a fixed hardware topology, like the GPU having a parent device.
This patch simply adds a few pci_is_root_bus() tests to avoid passing
a NULL pointer to PCI access functions, allowing the radeon driver to

This is a bit bigger hammer then I would like to use for this, but for now
it will have to make do. I'm working on getting my hands on one of these so
that I can try to get streams to work (with a quirk flag if necessary) and
then we can re-enable them.
For now this at least makes uas capable disk enclosures work again by forcing
fallback to the usb-storage driver.

Commit af040ffc9b ("ARM: make it easier to check the CPU part number
correctly") changed ARM_CPU_PART_X masks, and the way they are returned and
checked against. Usage of read_cpuid_part_number() is now deprecated, and
calling places updated accordingly. This actually broke cpuidle-big_little
initialization, as bl_idle_driver_init() performs a check using an hardcoded
mask on cpu_id.
Create an interface to perform the check (that is now even easier to read).
Define also a proper mask (ARM_CPU_PART_MASK) that makes this kind of checks
cleaner and helps preventing bugs in the future. Update usage accordingly.

Since we want to keep support for both older usb-phys as well as the
newer generic phys, lets first get the generic PHYs and fallback to
older USB-PHYs only when we fail to get the former.
This should fix the issue with ehci-exynos and ohci-exynos, wherein
in the absence of SAMSUNG_USB2PHY config symbol, we end up getting
the NOP_USB_XCEIV phy when the same is enabled. And thus the PHYs
are not configured properly.

Some elantech v3 touchpad equipped laptops also have a trackpoint, before
this commit, these give sync errors. With this patch, the trackpoint is
provided as another input device: 'Elantech PS/2 TrackPoint'
The patch will also output messages that do not follow the expected pattern.
In the mean time I've seen 2 unknown packets occasionally:
0x04 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00

A previous over-zealous factorisation of code means that we only treat
registers as volatile if they are readable. For most devices this is fine
since normally most registers can be read and volatility implies
readability but for format_write() devices where there is no readback from
the hardware and we use volatility to mean simply uncacheability this means
that we end up treating all registers as cacheble.
A bigger refactoring of the code to clarify this is in order but as a fix
make a minimal change and only check readability when checking volatility
if there is no format_write() operation defined for the device.

Possibly mdp5 needs something similar. The downstream android fbdev

87e956e9 changed the fault handler to return -ENOSYS, which causes the

if nothing ever faulted. But seems like some EXA composite operations
generate quite a lot of (seemingly harmless) faults. That is probably a
userspace problem, but the huge increase in verbosity from iommu fault
dumps makes things kind of unusable.

When looking at this driver for a client, I noticed the code that
configures the HSYNC pulse clobbers the display width in the same
register. It only preserves the MS part of the width in bit 3 and zeros
the LS part of the width in bits 9 to 4. This doesn't matter during
initialization as the width is configured afterwards, but subsequent use
of the FBIPUT_HSYNC ioctl would clobber the width.

Somehow the intel_ddi_set_vc_payload_alloc(false) call has ended up
in ironlake_crtc_disable() rather than haswell_crtc_disable(). Move it
to the correct place.
intel_ddi_disable_transcoder_func() already disables the vc payload
allocation so this doesn't actually do anything more. The spec
says we should wait for some kind of ack after frobbing the bit. We
don't appear to do that currently, but if and when someone decides
that we should do it, intel_ddi_set_vc_payload_alloc() would appear
to be be the right place for it. So having the function call in
haswell_crtc_disable() seems like the right thing for the future
even if it does nothing currently.

If we're runtime suspended and try to use the plane interfaces, we
will get a lot of WARNs saying we did the wrong thing.
We need to get runtime PM references to pin the objects, and to
change the fences. The pin functions are the ideal places for
this, but intel_crtc_cursor_set_obj() doesn't call them, so we also
have to add get/put calls inside it. There is no problem if we runtime
suspend right after these functions are finished, because the
registers written are forwarded to system memory.
Note: for a complete fix of the cursor-dpms test case, we also need
the patch named "drm/i915: Don't try to enable cursor from setplane
when crtc is disabled".
v2: - Narrow the put/get calls on intel_crtc_cursor_set_obj() (Daniel)
v3: - Make get/put also surround the fence and unpin calls (Daniel and
Ville).
- Merge all the plane changes into a single patch since they're
the same fix.
- Add the comment requested by Daniel.
v4: - Remove spurious whitespace (Ville).
v5: - Remove intel_crtc_update_cursor() chunk since Ville did an
equivalent fix in another patch (Ville).
v6: - Remove unpin chunk: it will be on a separate patch (Ville,
Chris, Daniel).
v7: - Same thing, new color.

If the device-tree specifies a max-memory-bandwidth property then the

however, this calculation is faulty for two reasons.
1. It doesn't ensure that the result is a sane value, i.e. a power of 2

2. It uses the displayed resolution and calculates the average bandwidth

This driver doesn't appear to support vlan acceleration at
all. However, it does claim to support TSO and IP checksums
for vlan devices. Thus any configured vlan device would
end up passing down partial checksums or TSO frames.
The driver also uses the value from skb->protocol to
determine TSO and checksum offload information, but assumes
that skb->protocol holds the l3 protocol information.
As a result, vlan traffic with partial checksums or TSO
will fail those checks and TSO will not happen.

The driver claims that it can do TSO and IP checksums on vlan
devices and also allows user to control vlan acceleration offloading.
This makes it possible to push traffic to this driver that has TSO or
partial checksums set, but also have a non-accelearted vlan
header. In this case, the driver will fail to correctly
identify such traffic and will not correctly perform
segmentation and checksum calculation.
Fix this by using vlan_get_protocol() helper instead of
assuming skb->protocol always has this information.

This device claims TSO and checksum support for vlans. It also

it is possible to turn off vlan acceleration and configure a vlan
which will continue to support TSO.
In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol

There is platform refusing to respond QR_EC when SCI_EVT isn't set
which is Acer Aspire V5-573G.
By disallowing QR_EC to be issued before the previous one has been
completed we are able to reduce the possibilities to trigger issues on
such platforms.
Note that this fix can only reduce the occurrence rate of this issue, but
this issue may still occur when such a platform doesn't clear SCI_EVT
before or immediately after completing the previous QR_EC transaction.
This patch cannot fix the CLEAR_ON_RESUME quirk which also relies on
the assumption that the platforms are able to respond even when SCI_EVT
isn't set.
But this patch is still useful as it can help to reduce the number of
scheduled QR_EC work items.

There is a platform refusing to respond QR_EC when SCI_EVT isn't set
(Acer Aspire V5-573G).
Currently, we rely on the behaviour that the EC firmware can respond
something (for example, 0x00 to indicate "no outstanding events") to
QR_EC even when SCI_EVT is not set, but the reporter has complained
about AC/battery pluging/unpluging and video brightness change delay
on that platform.
This is because the work item that has issued QR_EC has to wait until
timeout in this case, and the _Qxx method evaluation work item queued
after QR_EC one is delayed.
It sounds reasonable to fix this issue by:
1. Implementing SCI_EVT sanity check before issuing QR_EC in the EC
driver's main state machine.
2. Moving QR_EC issuing out of the work queue used by _Qxx evaluation
to a seperate IRQ handling thread.
This patch fixes this issue using solution 1.
By disallowing QR_EC to be issued when SCI_EVT isn't set, we are able to
handle such platform in the EC driver's main state machine. This patch
enhances the state machine in this way to survive with such malfunctioning
EC firmware.
Note that this patch can also fix CLEAR_ON_RESUME quirk which also relies
on the assumption that the platforms are able to respond even when SCI_EVT
isn't set.

Currently, notify callbacks for fixed button events are run from
interrupt context. That is not necessary and after commit 0bf6368ee8
(ACPI / button: Add ACPI Button event via netlink routine) it causes
netlink routines to be called from interrupt context which is not
correct.
Also, that is different from non-fixed device events (including
non-fixed button events) whose notify callbacks are all executed from
process context.
For the above reasons, make fixed button device notify callbacks run
in process context which will avoid the deadlock when using netlink
to report button events to user space.

We generally don't allow ACPI drivers to bind to ACPI device objects
that companion "physical" device objects are created for to avoid
situations in which two different drivers may attempt to handle one
device at the same time. Recent ACPI device enumeration rework
extended that approach to ACPI PNP devices by starting to use a scan
handler for enumerating them. However, we previously allowed ACPI
drivers to bind to ACPI device objects with existing PNP device
companions and changing that led to functional regressions on some
systems.
For this reason, add a special check for PNP devices in
acpi_device_probe() so that ACPI drivers can bind to ACPI device
objects having existing PNP device companions as before.

commit 65b97cf6b8 introduced in v3.7 caused a regression
by using a reversed CS_MASK thus causing omap_calculate_ecc to
always fail. As the NAND base driver never checks for .calculate()'s
return value, the zeroed ECC values are used as is without showing
any error to the user. However, this won't work and the NAND device
won't be guarded by any error code.
Fix the issue by using the correct mask.
Code was tested on omap3beagle using the following procedure
- flash the primary bootloader (MLO) from the kernel to the first
NAND partition using nandwrite.
- boot the board from NAND. This utilizes OMAP ROM loader that
relies on 1-bit Hamming code ECC.

For v3.12 and prior, 1-bit Hamming code ECC via software was the
default choice. Commit c66d039197 in v3.13 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.12
and prior to be unusable in v3.13 and later. So revert back to
using software ECC by default if an ECC scheme is not explicitely
specified.
This defect can be observed on the following boards during legacy boot

- ODROID booting was fixed due to PMIC interrupts missing in DT
- a collection of i.MX fixes
- minor Tegra fix for regulators
- Rockchip fix and addition of SoC-specific mailing list to make it
easier to find posted patches"

Here's our first set of fixes for v3.17-rc cycle. Most fixes are
pretty minor changes like the signedness bug in dwc3, or the wrong
string format on MUSB.
The most interesting part is the addition of Intel Quark X1000 support
to PCH UDC.

This patch fixes a potential security issue in the whiteheat USB driver
which might allow a local attacker to cause kernel memory corrpution. This
is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On
EHCI and XHCI busses it's possible to craft responses greater than 64
bytes leading a buffer overflow.
