The r592 driver relies on behavior of the DMA mapping API that is
normally observed but not guaranteed by the API. Instead it uses a
runtime check to fail transfers if the API ever behaves
When CONFIG_NEED_SG_DMA_LENGTH is not set, one of the checks turns into a
comparison of a variable with itself, which gcc-6.0 now warns about:
drivers/memstick/host/r592.c: In function 'r592_transfer_fifo_dma':
drivers/memstick/host/r592.c:302:31: error: self-comparison always evaluates to false [-Werror=tautological-compare]
(sg_dma_len(&dev->req->sg) < dev->req->sg.length)) {
^
The check itself is not a problem, so this patch just rephrases the
condition in a way that gcc does not consider an indication of a mistake.
We already know that dev->req->sg.length was initially R592_LFIFO_SIZE, so
we can compare it to that constant again.

This reverts commit e7223f18603374d235d8bb0398532323e5f318b9.
It causes problems when a ppdev tries to register before the parport
driver has been registered with the device model. That will trigger the
BUG_ON(!drv->bus->p);
at drivers/base/driver.c:153. The call chain is
kernel_init ->
kernel_init_freeable ->
do_one_initcall ->
ppdev_init ->
__parport_register_driver ->
driver_register *BOOM*

Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86
architectures plus some new device IDs and similar.
Specifics:
- Fix for an intel_pstate driver issue related to the handling of MSR
updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking fix
for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems from
hanging during initialization by disabling deep C-states mishandled
by the platform in the problematic configurations (Len Brown).
- Intel Xeon Phi Processor x200 support for intel_idle
(Dasaratharaman Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the fallback
C-state on x86 when they are set below its exit latency) and to
restore the previous behavior to fall back to C1 if the next timer
event is set far enough in the future that was changed in 4.4 which
led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space
resources on architectures where the IO space is memory mapped
(IA64 and ARM64) broken by the introduction of common ACPI
resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
- Fix for the ACPI backend of the generic device properties API to
make it parse non-device (data node only) children of an ACPI
device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven)"

Handle the Oscillator Failure ('OF') bit from Oscillator Status register

The autocalibration is separated in two bits to set in Oscillator
Control register (0x1c) :
- OSEL bit to select the oscillator type (XT or RC).
- ACAL bit to select the autocalibration type.
These functionnalities are exported in sysfs entries : "oscillator"
and "autocalibration". Respectively, the values are "xtal" for XT
oscillator and "rc" for RC oscillator and 0 to disable the
autocalibration cycle, 512 for a 512 seconds autocalibration cycle
and 1024 for a cycle of 1024 seconds.
Examples :
Set to XT Oscillator
echo xtal > /sys/class/rtc/rtc0/device/oscillator
Activate an autocalibration every 512 seconds
echo 512 > /sys/class/rtc/rtc0/device/autocalibration

The rv8803 has a 60µs window where it will not answer on the i2c bus.
It also means there will be no ack for the communication. Make sure
communication is tried multiple times when this happens (the i2c subsystem
mandates -ENXIO is that case but the number of retries is host specific).
The critical parts are the probe function and the alarm callback so make
sure we handle the failure there.

On these Lenovo laptops, a bogus passive trip point is reported,
which is 0 degree Celsius. Without commit 81ad4276b505, thermal zone
fails to set cooling devices to proper cooling state, which is a bug.
But with commit 81ad4276b505 applied, the processors are always

Some SKL-H configurations require "intel_idle.max_cstate=7" to boot.
While that is an effective workaround, it disables C10.
This patch detects the problematic configuration,
and disables C8 and C9, keeping C10 enabled.
Note that enabling SGX in BIOS SETUP can also prevent this issue,
if the system BIOS provides that option.

Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from

This removes the dependency on GPIOLIB for non faulty PHYs.
Indeed, without this patch, if GPIOLIB is not selected
devm_gpiod_get_optional() will return -ENOSYS and the driver probe
call will fail, regardless of the actual PHY hardware.
Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
only AT8030 presents the issues that commit 13a56b449325 ("net: phy:
at803x: Add support for hardware reset") attempts to work-around by
using a 'reset' GPIO line.
Hence, only AT8030 should depend on GPIOLIB operating properly.

The driver of course "knows" that the chip's reset signal is active low,
so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
all this will only work iff the GPIO is specified as active-high in the
device tree! I think both the driver and the device trees (if there are
any -- I was unable to find them) need to be fixed in this case...

GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
and hp_wmi_get_hw_state() to query its current hard and soft block state,
respectively.
In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
in an int value returned by firmware to get current block state: 0x200 <<
(r * 8) which with r being 3 for GPS results in overflow and mask of zero.
The same goes for hp_wmi_get_hw_state().
This effectively means that GPS rfkill on this WMI interface is considered
always both hard and soft blocked.
Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
this block to hardware firmware at least on my old nc6400 gets confused and
sets both hard and soft blocks on WiFi and BT.
This happens for example on hp-wmi module load.
Since due to overflow described above it is dubious that this ever worked
correctly and HP laptops with modems having GPS support seem to all have
been released well past year 2009 let's just remove GPS rfkill support via
pre-2009 WMI interface.

rfkill registration order in hp_wmi_rfkill_setup() is:
1) WiFi,
2) BT,
3) WWAN,
5) GPS.
Unregistration when cleaning up on error return should happen in reverse
order.
This means that: If BT rfkill fails to be allocated we possibly need to
first unregister WiFi rfkill before destroying it.
The same goes with (WWAN, BT) and (GPS, WWAN) pairs.
Also, if WWAN rfkill fails to register we need to (possibly) unregister BT
not the GPS one. And if GPS rfkill fails to register we need to unregister
WWAN not the BT one.
We never need to unregister GPS rfkill here since if GPS rfkill
registration succeeds this function returns without error so no cleanup is
necessary.

Similarly to Dell Vostro V131, Dell Inspiron M5110 also requires an
SMBIOS request to be issued in order for WMI events to be generated and
does not raise an i8042 interrupt when the Dell Instant Launch hotkey is
pressed. However, the event code for that hotkey on this machine is
0xe029, so add it to the legacy keymap.

On models on which an SMBIOS request needs to be issued in order for WMI
events to be generated, pressing the Dell Instant Launch hotkey does not
raise an i8042 interrupt - only a WMI event is generated (0xe025 on Dell
Vostro V131). As that WMI event is the only way the kernel will be
notified about pressing the Dell Instant Launch hotkey on such machines,
the relevant keymap entry has to be changed to a KE_KEY one. However,
the same WMI event should still be ignored on machines which do not
require an SMBIOS request for enabling WMI, so filter it conditionally
in dell_wmi_process_key().

On some laptop models (e.g. Dell Vostro V131), WMI events are not
generated until a specific SMBIOS request is issued to register an event
listener [1]. As there seems to be no ACPI method or SMBIOS request to
determine without possible side effects whether a given machine needs to
issue this SMBIOS request in order to receive WMI events, DMI matching
is used to whitelist the models which need it.

Some Lenovo ideapad models lack a physical rfkill switch.
On Lenovo models ideapad Y700 Touch-15ISK and ideapad Y700-15ISK,
ideapad-laptop would wrongly report all radios as blocked by
hardware which caused wireless network connections to fail.
Add these models without an rfkill switch to the no_hw_rfkill list.

Lifebook E734/E744/E754 has a radio toggle button which uses code 0x420.
Map it to KEY_RFKILL.

We want the size of the struct, not of a pointer to it. To be future
proof, just dereference the pointer to get the desired type.

The Kconfig currently controlling compilation of this code is:
drivers/platform/x86/Kconfig:config INTEL_SCU_IPC
drivers/platform/x86/Kconfig: bool "Intel SCU IPC Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_pci_driver() uses the same init level priority as
builtin_pci_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We don't replace module.h with init.h since the file already has that.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

During legacy suspend flow, IPC1 commands are being requested
from opregion driver. But the PMC_IPC1 command will timeout as example:
[ 281.444600] ipc_debug##: ipc_send_command: cmd=0x201ff,
[ 281.444648] wbuf[0]=0x4ea6
[ 281.444668] wbuf[1]=0x0
[ 281.444674] wbuf[2]=0x0
[ 281.444676] wbuf[3]=0x0
[ 284.446467] pmc-ipc-plat INT34D2:00: IPC timed out, TS=0x4, CMD=0x200ff
This is because before the opregion driver could send IPC1 commands,
the PMC_IPC irq is already suspended. Which makes the IPC command to
timeout.
Solution: register pmc_ipc irq as IRQF_NO_SUSPEND
