This patch fixes a few compiler warning in the efi code for unused
variable, discarding const qualifier and wrong pointer type:
drivers/firmware/efi/fdt.c|66 col 22| warning: unused variable ‘name’ [-Wunused-variable]
drivers/firmware/efi/efi.c|368 col 3| warning: passing argument 3 of ‘of_get_flat_dt_prop’ from incompatible pointer type [enabled by default]
drivers/firmware/efi/efi.c|368 col 8| warning: assignment discards ‘const’ qualifier from pointer target type [enabled by default]

In ISOC transfers, when free_slot points to the last TRB (i.e. Link
TRB), and all queued requests meet Missed Interval Isoc error, busy_slot
points to trb0.
busy_slot->trb0
trb1
...
free_slot->trb31(Link TRB)
After end transfer and receiving the XferNotReady event, trb_left is
caculated as 1 which is wrong, and no TRB will be primed to the
endpoint.
The root cause is free_slot is not increased the same way as busy_slot.
When busy_slot is increased by one, it checks if points to a link TRB
after increasement, but free_slot checks it before increasement.
free_slot should behave the same as busy_slot to make the trb_left
caculation correct.

When setting the rate of a clock, by default the clock framework will
change the parent of the clock to the most suitable one in
__clk_mux_determine_rate() (most suitable by looking at the clock rate).
This is a rather dangerous default, and causes problems on AM43x when
using display and ethernet. There are multiple ways to select the clock
muxes on AM43x, and some of those clock paths have the same source
clocks for display and ethernet. When changing the clock rate for the
display subsystem, the clock framework decides to change the display mux
from the dedicated display PLL to a shared PLL which is used by the
ethernet, and then changes the rate of the shared PLL, breaking the
ethernet.
As I don't think there ever is a case where we want the clock framework
to automatically change the parent clock of a clock mux, this patch sets
the CLK_SET_RATE_NO_REPARENT for all ti,mux-clocks.

With commit aed3f9d498b ("staging: comedi: addi_apci_1564:
absorb apci1564_reset()"), the apci 1564 driver has gained
a dependency on the addi watchdog module, which is not reflected
correctly in Kconfig, and that can lead to link errors
when the watchdog is disabled.
This adds an explicit 'select', like it is done in the other
addi apci drivers that need it.

Commit bd0fa9bb455d introduced a failure path to cpufreq_update_policy() if
cpufreq_driver->get(cpu) returns NULL. However, it jumps to the 'no_policy'
label, which exits without unlocking any of the locks the function acquired
earlier. This causes later calls into cpufreq to hang.
Fix this by creating a new 'unlock' label and jumping to that instead.

Jonathan writes:
First set of IIO fixes for the 3.16 cycle.
A mixed bag of fixes, many of which feel just to late for 3.15.
* hid sensors - some devices need a feature report request in order to
change power state. This isn't part of the spec, but has been observed
on several devices and does no harm to others.
* mpl3115 has had two errors in the buffer description fixed. The presure is
signed, not unsigned and the temperature has 12 bits rather than 16.
These could lead to incorrect interpretation of the data in userspace.
* tsl2x7x - the high byte of the proximity thresholds should be written along
with the low byte (which was). This could lead to interesting results
with large thresholds.
* twl4030 - a flag to specify processed values were required was not set
when initializing a reading. As such values returned were in an unknown
state. Fixed by simply initializing it appropriately.
* IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig
build errors.
* ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework
already performs one. As such for big endian systems, the bytes would be
in the wrong order in the magnetic field measurements reported.
* mxs-lradc - the controllable voltage dividers were not enabled / disabled for
later channels than the first one during conversion.
* at91_adc error handling returned -ENOMEM in a u8. Return value of
at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and
also original values to be returned.
* mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for
NULL to detect an error.

The commit 96c50caa5148 (net: fec: Enable IP header hardware checksum)
enable HW IP header checksum for IPV4 and IPV6, which causes IPV6 TCP/UDP
cannot work. (The issue is reported by Russell King)
For FEC IP header checksum function: Insert IP header checksum. This "IINS"
bit is written by the user. If set, IP accelerator calculates the IP header
checksum and overwrites the IINS corresponding header field with the calculated
value. The checksum field must be cleared by user, otherwise the checksum
always is 0xFFFF.
So the previous patch clear IP header checksum field regardless of IP frame
type.
In fact, IP HW detect the packet as IPV6 type, even if the "IINS" bit is set,
the IP accelerator is not triggered to calculates IPV6 header checksum because
IPV6 frame format don't have checksum.
So this results in the IPV6 frame being corrupted.
The patch just add software detect the current packet type, if it is IPV6
frame, it don't clear IP header checksum field.

Commit 9262c19d14c4 "usb: disable port power control if not supported in
wHubCharacteristics" gated enabling runtime pm for usb_port devices on
whether the parent hub supports power control, which causes a
regression. The port must still be allowed to carry out runtime pm
callbacks and receive a -EAGAIN or -EBUSY result. Otherwise the
usb_port device will transition to the pm error state and trigger the
same for the child usb_device.
Prior to the offending commit usb_hub_create_port_device() arranged for
runtime pm to be disabled is dev_pm_qos_expose_flags() failed. Instead,
force the default state of PM_QOS_FLAG_NO_POWER_OFF flag to be set prior
to enabling runtime pm. If that policy can not be set then fail
registration.

Commit d8521afe3586 "usb: assign default peer ports for root hubs"
delayed marking a hub valid (set hdev->maxchild) until it had been fully
configured and to enable the publishing of valid hubs to be serialized
by usb_port_peer_mutex.
However, xhci_update_hub_device() in some cases depends on
hdev->maxchild already being set. Do the minimal fix and move it after
the setting of hdev->maxchild.

This reverts commit ddb09754e6c7239e302c7b675df9bbd415f8de5d.
Linus objected to this originally, I can see why it might be needed, but
given that no one spoke up defending this patch, I'm going to revert it.
If you have hardware that requires this change, please speak up in the
future and defend the patch.

The ptp_pch driver is for a companion chip to the Intel Atom E600
series processors. These are 32-bit x86 processors so the driver is
only needed on X86_32.

pci_wait_for_pending() uses word access, so we shouldn't be passing
an offset that is only byte aligned. Use the control register offset
instead, shifting the mask to match.
Fixes: d0b4cc4e3270 ("PCI: Wrong register used to check pending traffic")
Fixes: 157e876ffe0b ("PCI: Add pci_wait_for_pending() (refactor pci_wait_for_pending_transaction())

There was a mistake in the actual rounding portion this previous patch:
f0fe3cd7e12d (intel_pstate: Correct rounding in busy calculation) such that
the rounding was asymetric and incorrect.
Severity: Not very serious, but can increase target pstate by one extra value.
For real world work flows the issue should self correct (but I have no proof).
It is the equivalent of different PID gains for positive and negative numbers.
Examples:
-3.000000 used to round to -4, rounds to -3 with this patch.
-3.503906 used to round to -5, rounds to -4 with this patch.
