This moves the "state" bus attribute to the dev_groups structure,
removing the need for it to be in a temporary structure.

This patch is the first in a series that moves the hv bus code to use the
dev_groups field instead of dev_attrs, as dev_attrs is going away in future
kernel releases.
It moves the id sysfs file to the dev_groups structure, and creates the needed
show/store functions, instead of relying on one "universal" function for this.
By doing this, it removes the need for this to be in a temporary structure.

suppressed" messages
pr_debug_ratelimited should be coded similarly to dev_dbg_ratelimited
to reduce the "callbacks suppressed" messages.
Add #include <linux/dynamic_debug.h> to printk.h. Unfortunately, this
new #include must be after the prototype/declaration of function printk.
It may be better to split out these _ratelimited declarations into
a separate file one day.
Any use of these pr_<foo>_ratelimited functions must also have another
specific #include <ratelimited.h>. Most users have this done indirectly
via #include <linux/kernel.h>
printk.h may not #include <linux/ratelimit.h> as it causes circular
dependencies and compilation failures.

usb: patches for v3.13
Final conversions to configfs for mass storage, acm_ms, and
multi gadgets.
MUSB should now work out of the box on AM335x-based boards
(beagle bone white and black) with DMA thanks to Sebastian's
work.
We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/
by selecting CONFIG_USB_GADGET_VERBOSE.
s3c-hsotg got quite a few non-critical fixes but also learned
a few new tricks (isochronous transfers, multi count support).
The Marvel USB3 Controller driver got a memory leak fix.
devm_usb_get_phy() learned not to return NULL, ever.
Other than these patches, we have the usual set of cleanups
ranging from removal of unnecessary *_set_drvdata() to using
SIMPLE_DEV_PM_OPS.

This adds RCAR Gen2 USB phy support. The driver configures
USB channels 0/2 which are shared between PCI USB hosts and
USBHS/USBSS devices. It also controls internal USBHS phy.

xhci: Final patches for 3.13
Hi Greg,
Here's my pull request for usb-next and 3.13. My xHCI tree is closed
after this point, since I won't be able to run my full tests while I'm in
Scotland. After Kernel Summit, I'll be on vacation with access to email
from Oct 26th to Nov 6th.
Here's what's in this request:
- Patches to fix USB 2.0 Link PM issues that cause USB 3.0 devices to not
enumerate or misbehave when plugged into a USB 2.0 port. Those are
marked for stable.
- A msec vs jiffies bug fix by xiao jin, which results in fairly harmless
behavior, and thus isn't marked for stable.
- Xenia's patches to refactor the xHCI command handling code, which makes
it much more readable and consistent.
- Misc cleanup patches, one by Sachin Kamat and three from Dan Williams.
Here's what's not in this request:
- Dan's two patches to allow the xHCI host to use the "Windows" or "new"
enumeration scheme. I did not have time to test those, and I want to
run them with as many USB devices as I can get a hold of. That will
have to wait for 3.14.
- Xenia's patches to remove xhci_readl in favor of readl. I'll queue
those for 3.14 after I test them.
- The xHCI streams update, UAS fixes, and usbfs streams support. I'm not
comfortable with changes and fixes to that patchset coming in this late.
I would rather wait for 3.14 and be really sure the streams support is
stable before we add new userspace API and remove CONFIG_BROKEN from the
uas driver.
- Julius' patch to clear the port reset bit on hub resume that came in
a couple days ago. It looks harmless, but I would rather take the time
to test and queue it for usb-linus and the stable trees once 3.13-rc1
is out.

How it's supposed to work:
--------------------------
USB 2.0 Link PM is a lower power state that some newer USB 2.0 devices
support. USB 3.0 devices certified by the USB-IF are required to
support it if they are plugged into a USB 2.0 only port, or a USB 2.0
cable is used. USB 2.0 Link PM requires both a USB device and a host
controller that supports USB 2.0 hardware-enabled LPM.
USB 2.0 Link PM is designed to be enabled once by software, and the host
hardware handles transitions to the L1 state automatically. The premise
of USB 2.0 Link PM is to be able to put the device into a lower power
link state when the bus is idle or the device NAKs USB IN transfers for
a specified amount of time.
...but hardware is broken:
--------------------------
It turns out many USB 3.0 devices claim to support USB 2.0 Link PM (by
setting the LPM bit in their USB 2.0 BOS descriptor), but they don't
actually implement it correctly. This manifests as the USB device
refusing to respond to transfers when it is plugged into a USB 2.0 only
port under the Haswell-ULT/Lynx Point LP xHCI host.
These devices pass the xHCI driver's simple test to enable USB 2.0 Link
PM, wait for the port to enter L1, and then bring it back into L0. They
only start to break when L1 entry is interleaved with transfers.
Some devices then fail to respond to the next control transfer (usually
a Set Configuration). This results in devices never enumerating.
Other mass storage devices (such as a later model Western Digital My
Passport USB 3.0 hard drive) respond fine to going into L1 between
control transfers. They ACK the entry, come out of L1 when the host
needs to send a control transfer, and respond properly to those control
transfers. However, when the first READ10 SCSI command is sent, the
device NAKs the data phase while it's reading from the spinning disk.
Eventually, the host requests to put the link into L1, and the device
ACKs that request. Then it never responds to the data phase of the
READ10 command. This results in not being able to read from the drive.
Some mass storage devices (like the Corsair Survivor USB 3.0 flash
drive) are well behaved. They ACK the entry into L1 during control
transfers, and when SCSI commands start coming in, they NAK the requests
to go into L1, because they need to be at full power.
Not all USB 3.0 devices advertise USB 2.0 link PM support. My Point
Grey USB 3.0 webcam advertises itself as a USB 2.1 device, but doesn't
have a USB 2.0 BOS descriptor, so we don't enable USB 2.0 Link PM. I
suspect that means the device isn't certified.
What do we do about it?
-----------------------
There's really no good way for the kernel to test these devices.
Therefore, the kernel needs to disable USB 2.0 Link PM by default, and
distros will have to enable it by writing 1 to the sysfs file
/sys/bus/usb/devices/../power/usb2_hardware_lpm. Rip out the xHCI Link
PM test, since it's not sufficient to detect these buggy devices, and
don't automatically enable LPM after the device is addressed.
This patch should be backported to kernels as old as 3.11, that
contain the commit a558ccdcc71c7770c5e80c926a31cfe8a3892a09 "usb: xhci:
add USB2 Link power management BESL support". Without this fix, some
USB 3.0 devices will not enumerate or work properly under USB 2.0 ports
on Haswell-ULT systems.

Do not overwrite the multi-byte fields of usb_wa_descriptor with their
cpu format values after reading the descriptor. Leave the values as
__le16 and swap on use. This is more consistent with other uses of USB

Host controller drivers use the NS_TO_US macro to convert transaction
times, which are computed in nanoseconds, to microseconds for
scheduling. Periodic scheduling requires worst-case estimates, but
the macro does its conversion using round-to-nearest. This patch
changes it to use round-up, giving a correct worst-case value.

usb_wait_anchor_empty_timeout() should wait till the completion handler
has run. Both the zd1211rw driver and the uas driver (in its task mgmt) depend
on the completion handler having completed when usb_wait_anchor_empty_timeout()
returns, as they read state set by the completion handler after an
usb_wait_anchor_empty_timeout() call.
But __usb_hcd_giveback_urb() calls usb_unanchor_urb before calling the
completion handler. This is necessary as the completion handler may
re-submit and re-anchor the urb. But this introduces a race where the state
these drivers want to read has not been set yet by the completion handler
(this race is easily triggered with the uas task mgmt code).
I've considered adding an anchor_count to struct urb, which would be
incremented on anchor and decremented on unanchor, and then only actually
do the anchor / unanchor on 0 -> 1 and 1 -> 0 transtions, combined with
moving the unanchor call in hcd_giveback_urb to after calling the completion
handler. But this will only work if urb's are only re-anchored to the same
anchor as they were anchored to before the completion handler ran.
And at least one driver re-anchors to another anchor from the completion
handler (rtlwifi).
So I have come up with this patch instead, which adds the ability to
suspend wakeups of usb_wait_anchor_empty_timeout() waiters to the usb_anchor
functionality, and uses this in __usb_hcd_giveback_urb() to delay wake-ups
until the completion handler has run.

And do so in a way which ensures that any fields added in the future will
also get properly zero-ed.

omap_get_control_dev() is being deprecated as it doesn't support
multiple instances. As control device is present only from OMAP4
onwards which supports DT only, we use phandles to get the

Also get rid of "ti,has-mailbox" property as it is redundant and
we can determine that from whether "ctrl-module" property is present
or not. Get rid of has_mailbox from musb_hdrc_platform_data as well.

Add support for new device types and in the process rid of "ti,type"
device tree property. The correct type of device will be determined
from the compatible string instead.
Introduce a compatible string for each device type. At the moment
we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2.
Update DT binding information to reflect these changes.
Also get rid of omap_control_usb3_phy_power(). Just one function
i.e. omap_control_usb_phy_power() will now take care of all PHY types.

Used the generic PHY framework API to create the PHY. For powering on
and powering off the PHY, power_on and power_off ops are used. Once the
MUSB OMAP glue is adapted to the new framework, the suspend and resume
ops of usb phy library will be removed. Also twl4030-usb driver is moved
to drivers/phy/.
However using the old usb phy library cannot be completely removed
because otg is intertwined with phy and moving to the new
framework completely will break otg. Once we have a separate otg state machine,
we can get rid of the usb phy library.

The PHY framework provides a set of APIs for the PHY drivers to
create/destroy a PHY and APIs for the PHY users to obtain a reference to the
PHY with or without using phandle. For dt-boot, the PHY drivers should
also register *PHY provider* with the framework.
PHY drivers should create the PHY by passing id and ops like init, exit,
power_on and power_off. This framework is also pm runtime enabled.
The documentation for the generic PHY framework is added in
Documentation/phy.txt and the documentation for dt binding can be found at
Documentation/devicetree/bindings/phy/phy-bindings.txt

The following patch is required to resolve remote wake issues with
certain devices.
Issue description:
If the remote wake is issued from the device in a specific timing
condition while the system is entering sleep state then it may cause
system to auto wake on subsequent sleep cycle.
Root cause:
Host controller rebroadcasts the Resume signal > 100 µseconds after
receiving the original resume event from the device. For proper
function, some devices may require the rebroadcast of resume event
within the USB spec of 100µS.
Workaroud:
1. Filter the AMD platforms with Yangtze chipset, then judge of all the usb
devices are mouse or not. And get out the port id which attached a mouse
with Pixart controller.
2. Then reset the port which attached issue device during system resume
from S3.
[Q] Why the special devices are only mice? Would high speed devices
such as 3G modem or USB Bluetooth adapter trigger this issue?
- Current this sensitivity is only confined to devices that use Pixart
controllers. This controller is designed for use with LS mouse
devices only. We have not observed any other devices failing. There
may be a small risk for other devices also but this patch (reset
device in resume phase) will cover the cases if required.
[Q] Shouldn’t the resume signal be sent within 100 us for every
device?
- The Host controller may not send the resume signal within 100us,
this our host controller specification change. This is why we
require the patch to prevent side effects on certain known devices.
[Q] Why would clicking mouse INTENSELY to wake the system up trigger
this issue?
- This behavior is specific to the devices that use Pixart controller.
It is timing dependent on when the resume event is triggered during
the sleep state.
[Q] Is it a host controller issue or mouse?
- It is the host controller behavior during resume that triggers the
device incorrect behavior on the next resume.
This patch sets USB_QUIRK_RESET_RESUME flag for these Pixart-based mice
when they attached to platforms with AMD Yangtze chipset.

Now that URBs can be completed inside tasklets, we need a way of
determining whether a completion handler for a given endpoint is
currently running. Otherwise it's not possible to maintain the API
guarantee about keeping isochronous streams synchronous when an
underrun occurs.
This patch adds a field and a routine to check whether a completion
handler for a periodic endpoint is running. At the moment no
analogous routine appears to be necessary for async endpoints, but one
can always be added.

Right now skb->data is passed to rx_hook() even if the skb
has not been linearised and without giving rx_hook() a way
to linearise it.
Change the rx_hook() interface and make it accept the skb
and the offset to the UDP payload as arguments. rx_hook() is
also renamed to rx_skb_hook() to ensure that out of the tree
users notice the API change.
In this way any rx_skb_hook() implementation can perform all
the needed operations to properly (and safely) access the
skb data.

Negative message lengths make no sense -- so don't do negative queue
lenghts or identifier counts. Prevent them from getting negative.
Also change the underlying data types to be unsigned to avoid hairy
surprises with sign extensions in cases where those variables get
evaluated in unsigned expressions with bigger data types, e.g size_t.
In case a user still wants to have "unlimited" sizes she could just use
INT_MAX instead.

this_cpu_sub() is implemented as negation and addition.
This patch casts the adjustment to the counter type before negation to
sign extend the adjustment. This helps in cases where the counter type
is wider than an unsigned adjustment. An alternative to this patch is
to declare such operations unsupported, but it seemed useful to avoid
surprises.
This patch specifically helps the following example:
unsigned int delta = 1
preempt_disable()
this_cpu_write(long_counter, 0)
this_cpu_sub(long_counter, delta)
preempt_enable()
Before this change long_counter on a 64 bit machine ends with value
0xffffffff, rather than 0xffffffffffffffff. This is because
this_cpu_sub(pcp, delta) boils down to this_cpu_add(pcp, -delta),
which is basically:
long_counter = 0 + 0xffffffff
Also apply the same cast to:
__this_cpu_sub()
__this_cpu_sub_return()
this_cpu_sub_return()
All percpu_test.ko passes, especially the following cases which
previously failed:
l -= ui_one;
__this_cpu_sub(long_counter, ui_one);
CHECK(l, long_counter, -1);
l -= ui_one;
this_cpu_sub(long_counter, ui_one);
CHECK(l, long_counter, -1);
CHECK(l, long_counter, 0xffffffffffffffff);
ul -= ui_one;
__this_cpu_sub(ulong_counter, ui_one);
CHECK(ul, ulong_counter, -1);
CHECK(ul, ulong_counter, 0xffffffffffffffff);
ul = this_cpu_sub_return(ulong_counter, ui_one);
CHECK(ul, ulong_counter, 2);
ul = __this_cpu_sub_return(ulong_counter, ui_one);
CHECK(ul, ulong_counter, 1);

Pull networking fixes from David Miller:
"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.
22) Fix PHY reset and other issues in dm9000 driver, from Nikita
Kiryanov and Michael Abbott.
23) When hardware can do SCTP crc32 checksums, we accidently don't
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.
32) Fix identification of fragmented frames in ipv4/ipv6 UDP
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.

We cap bitrate at YAM_MAXBITRATE in yam_ioctl(), but it could also be
negative. I don't know the impact of using a negative bitrate but let's
prevent it.

Commit 3fa4d734 (usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv)
changed the conditional around the declaration of usb_nop_xceiv_register
from
#if defined(CONFIG_NOP_USB_XCEIV) ||
(defined(CONFIG_NOP_USB_XCEIV_MODULE) && defined(MODULE))
to
#if IS_ENABLED(CONFIG_NOP_USB_XCEIV)
While that looks the same, it is semantically different. The first expression
is true if CONFIG_NOP_USB_XCEIV is built as module and if the including
code is built as module. The second expression is true if code depending on
CONFIG_NOP_USB_XCEIV if built as module or into the kernel.
As a result, the arm:allmodconfig build fails with
arch/arm/mach-omap2/built-in.o: In function `omap3_evm_init':
arch/arm/mach-omap2/board-omap3evm.c:703: undefined reference to
`usb_nop_xceiv_register'
Fix the problem by reverting to the old conditional.

Some USB drive enclosures do not correctly report an
overflow condition if they hold a drive with a capacity
over 2TB and are confronted with a READ_CAPACITY_10.
They answer with their capacity modulo 2TB.
The generic layer cannot cope with that. It must be told
to use READ_CAPACITY_16 from the beginning.

Commit 3812c8c8f395 ("mm: memcg: do not trap chargers with full
callstack on OOM") assumed that only a few places that can trigger a
memcg OOM situation do not return VM_FAULT_OOM, like optional page cache
readahead. But there are many more and it's impractical to annotate
them all.
First of all, we don't want to invoke the OOM killer when the failed
allocation is gracefully handled, so defer the actual kill to the end of
the fault handling as well. This simplifies the code quite a bit for
added bonus.
Second, since a failed allocation might not be the abrupt end of the
fault, the memcg OOM handler needs to be re-entrant until the fault
finishes for subsequent allocation attempts. If an allocation is
attempted after the task already OOMed, allow it to bypass the limit so
that it can quickly finish the fault and invoke the OOM killer.

Pull device tree fixes and reverts from Grant Likely:
"One bug fix and three reverts. The reverts back out the slightly
controversial feeding the entire device tree into the random pool and
the reserved-memory binding which isn't fully baked yet. Expect the
reserved-memory patches at least to resurface for v3.13.
The bug fixes removes a scary but harmless warning on SPARC that was
introduced in the v3.12 merge window. v3.13 will contain a proper fix
that makes the new code work on SPARC.
On the plus side, the diffstat looks *awesome*. I love removing lines
of code"

This reverts commit 9d8eab7af79cb4ce2de5de39f82c455b1f796963. There is
still no consensus on the bindings for the reserved memory and various
drawbacks of the proposed solution has been shown, so the best now is to
revert it completely and start again from scratch later.
