Pull power management fixes from Rafael Wysocki:
"These fix several issues in the intel_pstate driver and one issue in
the schedutil cpufreq governor, clean up that governor a bit and hook
up existing code for disabling cpufreq to a new kernel command line
option.
Specifics:
- Three fixes for intel_pstate problems related to the passive mode
(in which it acts as a regular cpufreq scaling driver), two for the
handling of global P-state limits and one for the handling of the
cpu_frequency tracepoint in that mode (Rafael Wysocki).
- Three fixes for the handling of P-state limits in intel_pstate in
the active mode (Rafael Wysocki).
- Introduction of a new cpufreq.off=1 kernel command line argument
that will disable cpufreq entirely if passed to the kernel and is
simply hooked up to the existing code used by Xen (Len Brown).
- Fix for the schedutil cpufreq governor to prevent it from using
stale raw frequency values in configurations with mutiple CPUs
sharing one policy object and a cleanup for it reducing its
overhead slightly (Viresh Kumar)"

In qed_ll2_start_ooo() the ll2_info variable is uninitialized and then
passed to qed_ll2_acquire_connection() where it is copied into a new
memory space.
This shouldn't cause any issue as long as non of the copied memory is
every read.
But the potential for a bug being introduced by reading this memory
is real.

ACPI support has been added to ARM IOMMU driver in 4.10 kernel
and that has resulted in VNIC interfaces throwing translation
faults when kernel is booted with ACPI as driver was not using
DMA API. This patch fixes the issue by using DMA API which inturn
will create translation tables when IOMMU is enabled.
Also VNIC doesn't have a seperate receive buffer ring per receive
queue, so there is no 1:1 descriptor index matching between CQE_RX
and the index in buffer ring from where a buffer has been used for
DMA'ing. Unlike other NICs, here it's not possible to maintain dma
address to virt address mappings within the driver. This leaves us
no other choice but to use IOMMU's IOVA address conversion API to
get buffer's virtual address which can be given to network stack
for processing.

Improve UDP TX performance by:
* reducing the ring size from 2K to 512
* replacing the numerous streaming DMA allocations for info buffers and
gather lists with one large consistent DMA allocation per ring
BQL is not effective here. We reduced the ring size because there is heavy
overhead with dma_map_single every so often. With iommu=on, dma_map_single
in PF Tx data path was taking longer time (~700usec) for every ~250
packets. Debugged intel_iommu code, and found that PF driver is utilizing
too many static IO virtual address mapping entries (for gather list entries
and info buffers): about 100K entries for two PF's each using 8 rings.
Also, finding an empty entry (in rbtree of device domain's iova mapping in
kernel) during Tx path becomes a bottleneck every so often; the loop to
find the empty entry goes through over 40K iterations; this is too costly
and was the major overhead. Overhead is low when this loop quits quickly.

Neil Brown pointed out a potential deadlock in raid 10 code with
bio_split/chain. The raid1 code could have the same issue, but recent
barrier rework makes it less likely to happen. The deadlock happens in
below sequence:
1. generic_make_request(bio), this will set current->bio_list
2. raid10_make_request will split bio to bio1 and bio2
3. __make_request(bio1), wait_barrer, add underlayer disk bio to
current->bio_list
4. __make_request(bio2), wait_barrer
If raise_barrier happens between 3 & 4, since wait_barrier runs at 3,
raise_barrier waits for IO completion from 3. And since raise_barrier
sets barrier, 4 waits for raise_barrier. But IO from 3 can't be
dispatched because raid10_make_request() doesn't finished yet.
The solution is to adjust the IO ordering. Quotes from Neil:
"
It is much safer to:
if (need to split) {
split = bio_split(bio, ...)
bio_chain(...)
make_request_fn(split);
generic_make_request(bio);
} else
make_request_fn(mddev, bio);
This way we first process the initial section of the bio (in 'split')
which will queue some requests to the underlying devices. These
requests will be queued in generic_make_request.
Then we queue the remainder of the bio, which will be added to the end
of the generic_make_request queue.
Then we return.
generic_make_request() will pop the lower-level device requests off the
queue and handle them first. Then it will process the remainder
of the original bio once the first section has been fully processed.
"
Note, this only happens in read path. In write path, the bio is flushed to
underlaying disks either by blk flush (from schedule) or offladed to raid1/10d.
It's queued in current->bio_list.

Upstream commit 98d74f9ceaef ("xhci: fix 10 second timeout on removal of
PCI hotpluggable xhci controllers") fixes a problem with hot pluggable PCI
xhci controllers which can result in excessive timeouts, to the point where
the system reports a deadlock.
The same problem is seen with hot pluggable xhci controllers using the
xhci-plat driver, such as the driver used for Type-C ports on rk3399.
Similar to hot-pluggable PCI controllers, the driver for this chip
removes the xhci controller from the system when the Type-C cable is
disconnected.
The solution for PCI devices works just as well for non-PCI devices
and avoids the problem.

After commit 7999eecb7e56 ("i2c: exynos5: fix arbitration lost handling"),
some I2C transactions are failing because the TRANSFER_DONE_AUTO field is
not set in the I2C_TRANS_STATUS register so the i2c->status value is left
to -EINVAL causing the i2c->msg_complete completion to never be signaled.
For example, when reading the time of an I2C rtc on an Exynos5800 machine:
$ cat /sys/class/rtc/rtc0/time
[ 25.924594] exynos5-hsi2c 12e10000.i2c: rx timeout
[ 65.028365] max77686-rtc max77802-rtc: Fail to read time reg(-22)
cat: /sys/class/rtc/rtc0/time: Invalid argument
The Exynos5422 manual states clearly that most I2C_TRANS_STATUS reg bits
(including TRANSFER_DONE_AUTO) are cleared after the register is read. So
reading has side effects and should only be done if HSI2C_INT_I2C was set.

Interrupt handling routine was calling req->base.complete() under
spinlock. In most cases this wasn't fatal but when combined with some
of the cipher modes (like LRW) this caused recursion - starting the new
encryption (s5p_aes_crypt()) while still holding the spinlock from
previous round (s5p_aes_complete()).
Beside that, the s5p_aes_interrupt() error handling path could execute
two completions in case of error for RX and TX blocks.
Rewrite the interrupt handling routine and the completion by:
1. Splitting the operations on scatterlist copies from
s5p_aes_complete() into separate s5p_sg_done(). This still should be
done under lock.
The s5p_aes_complete() now only calls req->base.complete() and it has
to be called outside of lock.
2. Moving the s5p_aes_complete() out of spinlock critical sections.
In interrupt service routine s5p_aes_interrupts(), it appeared in few
places, including error paths inside other functions called from ISR.
This code was not so obvious to read so simplify it by putting the
s5p_aes_complete() only within ISR level.

USB-serial fixes for v4.11-rc2
Here's a fix for a digi_acceleport regression in -rc1, and some fixes
for long-standing issues in three other drivers, including a
NULL-pointer dereference and a couple of information leaks that could be
triggered by a malicious device.

We get the following compile errors if EXTCON is enabled as a

so let's mark this as needing to follow the modular status of
the extcon framework.

This reverts commit d7bc1a7d41bf ("phy: Add USB3 PHY support for
Broadcom NSP SoC") as we already have driver for this PHY (shared by NS
and NSP). It was added in commit e5666281d9ea ("phy: bcm-ns-usb3: new
driver for USB 3.0 PHY on Northstar").
Instead of adding separated driver & duplicating code we should work on
improving existing (old) one. Thanks to work done by Broadcom we know
there is MDIO bus we weren't aware of & we know register names which
makes initialization more clear. This is very valuable info and we
should work on using it in existing driver afterwards.

A recent change claimed to fix an off-by-one error in the OOB-port
completion handler, but instead introduced such an error. This could
specifically led to modem-status changes going unnoticed, effectively
breaking TIOCMGET.
Note that the offending commit fixes a loop-condition underflow and is
marked for stable, but should not be backported without this fix.

Rename oc-delay-* to oc-delay-us and make it expect a time value.
Furthermore add -ms suffix to power-on-time. There changes were

Make sure to check for the required interrupt-in endpoint to avoid
dereferencing a NULL-pointer should a malicious device lack such an
endpoint.
Note that a fairly recent change purported to fix this issue, but added
an insufficient test on the number of endpoints only, a test which can
now be removed.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

In patch 2e2aa1bc7eff90ecm, USB suspend and wakeup control requests are
passed to SFR_OHCIICR register. If a processor does not have such a
register, this hub control request will be dropped.
If no such a SFR register is available, all USB suspend control requests
will now be processed using ohci_hub_control()
(like before patch 2e2aa1bc7eff90ecm.)
Tested on an Atmel AT91SAM9G20 with an on-board TI TUSB2046B hub chip
If the last USB device is unplugged from the USB hub, the hub goes into
sleep and will not wakeup when an USB devices is inserted.

If we have any residual freed atomic state from earlier commits, flush
the freed list after performing the current modeset. This prevents the
freed list from ever-growing if userspace manages to starve the kernel
threads (i.e. we are never able to run our free state worker and
eventually the system may even oom).
