Some Lenovo ideapad models do not have hardware rfkill switches, but
trying to read the rfkill switches through the ideapad-laptop module.
It caused to always reported blocking breaking wifi.
Fix it by adding those models to no_hw_rfkill_list.

Like other Lenovo models the IdeaPad V510-15IKB does not have an hw
rfkill switch. This results in hard-blocked radios after boot, resulting
in always blocked radios rendering them unusable.
Add the IdeaPad V510-15IKB to the no_hw_rfkill DMI list and allows using
the built-in radios.

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris:
- a major update for AppArmor. From JJ:
* several bug fixes and cleanups
* the patch to add symlink support to securityfs that was floated
on the list earlier and the apparmorfs changes that make use of
securityfs symlinks
* it introduces the domain labeling base code that Ubuntu has been
carrying for several years, with several cleanups applied. And it
converts the current mediation over to using the domain labeling
base, which brings domain stacking support with it. This finally
will bring the base upstream code in line with Ubuntu and provide
a base to upstream the new feature work that Ubuntu carries.
* This does _not_ contain any of the newer apparmor mediation
features/controls (mount, signals, network, keys, ...) that
Ubuntu is currently carrying, all of which will be RFC'd on top
of this.
- Notable also is the Infiniband work in SELinux, and the new file:map
permission. From Paul:
"While we're down to 21 patches for v4.13 (it was 31 for v4.12),
the diffstat jumps up tremendously with over 2k of line changes.
Almost all of these changes are the SELinux/IB work done by
Daniel Jurgens; some other noteworthy changes include a NFS v4.2
labeling fix, a new file:map permission, and reporting of policy
capabilities on policy load"
There's also now genfscon labeling support for tracefs, which was
lost in v4.1 with the separation from debugfs.
- Smack incorporates a safer socket check in file_receive, and adds a
cap_capable call in privilege check.
- TPM as usual has a bunch of fixes and enhancements.
- Multiple calls to security_add_hooks() can now be made for the same
LSM, to allow LSMs to have hook declarations across multiple files.
- IMA now supports different "ima_appraise=" modes (eg. log, fix) from
the boot command line.

It is observed reading the register from HW takes a bit long,
for example in my box, the following difference of 'perf report
--no-children fio ...' can be seen when running I/O:
1) V4.12 without patch
+ 9.28% fio [mtip32xx] [k] mtip_irq_handler
+ 8.48% fio [mtip32xx] [k] mtip_init_cmd_header
2) V4.12 with the following patch
+ 9.14% fio [mtip32xx] [k] mtip_irq_handler
......
+ 1.14% fio [mtip32xx] [k] mtip_init_cmd_header
IOPS can be increased by ~5% with this patch too.

The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).
There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.
Implement driver support for device-tree property meant to advertise
the wrong strapping.

ABI 4.x introduced the chained metadata format and made it the
only one possible. There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath. In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities. The default was left to non-chained.
In case of fallback traffic, there is no capability telling the
driver there may be chained metadata. With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.
This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway. New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

The legacy MAC address lookup doesn't work well with breakout
cables. We are probably better off picking random addresses
than the wrong ones in the theoretical scenario where management
FW didn't tell us what the port config is.

For historical reasons we enumerate the vNICs in order. This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.
What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.
Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:
pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2
Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

The Prefix CCW is not mandatory and raw I/O can also be issued without
it. Check whether the Prefix CCW is supported and if not use the
combination of Define Extent and Locate Record Extended instead.
While at it, sort the variable declarations, replace the gotos with
early exits, and remove an error check at the end which is irrelevant.
Also, remove the XRC check as it is not relevant for raw I/O.

We already have define_extent() that prepares necessary data for the
Define Extent CCW. The exact same thing is done in prefix_LRE().
Remove the duplicate code and move commands that were only used in
combination with the Prefix command to define_extent(). One of these
commands needs the blocksize to be specified. Add the blksize parameter
to define_extent() to account for that.
In addition, the check_XRC() function can be made more generic. Do this
and remove the Prefix-specific check_XRC_on_prefix() function.
Furthermore, prefix_LRE() uses fill_LRE_data() to prepare Locate Record
Extended data. Rename the function to fit the scheme better and make it
usable outside of the Prefix context by adding the corresponding CCW
command.

Pull ACPI updates from Rafael Wysocki:
"These mostly update the ACPICA code in the kernel to upstream revision
20170531 which covers all of the new material from ACPI 6.2, including
new tables (WSMT, HMAT, PPTT), new subtables and definition changes
for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource
descriptor macros for pin control, support for new predefined methods
(_LSI, _LSR, _LSW, _HMA), fixes and cleanups.
On top of that, an additional ACPICA change from Kees (which also is
upstream already) switches all of the definitions of function pointer
structures in ACPICA to use designated initializers so as to make the
structure layout randomization GCC plugin work with it.
The rest is a few fixes and cleanups in the EC driver, an xpower PMIC
driver update, a new backlight blacklist entry, and update of the
tables configfs interface and a messages formatting cleanup.
Specifics:
- Update the ACPICA code in the kernel to upstream revision revision

Pull power management updates from Rafael Wysocki:
"The big ticket items here are the rework of suspend-to-idle in order
to add proper support for power button wakeup from it on recent Dell
laptops and the rework of interfaces exporting the current CPU
frequency on x86.
In addition to that, support for a few new pieces of hardware is
added, the PCI/ACPI device wakeup infrastructure is simplified
significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
bus locking infrastructure.
Also, there are some functional improvements for intel_pstate, tools
updates and small fixes and cleanups all over.
Specifics:
- Rework suspend-to-idle to allow it to take wakeup events signaled
by the EC into account on ACPI-based platforms in order to properly
support power button wakeup from suspend-to-idle on recent Dell
laptops (Rafael Wysocki).
That includes the core suspend-to-idle code rework, support for the
Low Power S0 _DSM interface, and support for the ACPI INT0002
Virtual GPIO device from Hans de Goede (required for USB keyboard
wakeup from suspend-to-idle to work on some machines).
- Stop trying to export the current CPU frequency via /proc/cpuinfo
on x86 as that is inaccurate and confusing (Len Brown).
- Rework the way in which the current CPU frequency is exported by
the kernel (over the cpufreq sysfs interface) on x86 systems with
the APERF and MPERF registers by always using values read from
these registers, when available, to compute the current frequency
regardless of which cpufreq driver is in use (Len Brown).
- Rework the PCI/ACPI device wakeup infrastructure to remove the
questionable and artificial distinction between "devices that can
wake up the system from sleep states" and "devices that can
generate wakeup signals in the working state" from it, which allows
the code to be simplified quite a bit (Rafael Wysocki).
- Fix the wakeup IRQ framework by making it use SRCU instead of RCU
which doesn't allow sleeping in the read-side critical sections,
but which in turn is expected to be allowed by the IRQ bus locking
infrastructure (Thomas Gleixner).
- Modify some computations in the intel_pstate driver to avoid
rounding errors resulting from them (Srinivas Pandruvada).
- Reduce the overhead of the intel_pstate driver in the HWP
(hardware-managed P-states) mode and when the "performance" P-state
selection algorithm is in use by making it avoid registering
scheduler callbacks in those cases (Len Brown).
- Rework the energy_performance_preference sysfs knob in intel_pstate
by changing the values that correspond to different symbolic hint
names used by it (Len Brown).
- Make it possible to use more than one cpuidle driver at the same
time on ARM (Daniel Lezcano).
- Make it possible to prevent the cpuidle menu governor from using
the 0 state by disabling it via sysfs (Nicholas Piggin).
- Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1 on
AMD systems (Yazen Ghannam).
- Make the CPPC cpufreq driver take the lowest nonlinear performance
information into account (Prashanth Prakash).
- Add support for hi3660 to the cpufreq-dt driver, fix the imx6q
driver and clean up the sfi, exynos5440 and intel_pstate drivers
(Colin Ian King, Krzysztof Kozlowski, Octavian Purdila, Rafael
Wysocki, Tao Wang).
- Fix a few minor issues in the generic power domains (genpd)
framework and clean it up somewhat (Krzysztof Kozlowski, Mikko
Perttunen, Viresh Kumar).
- Fix a couple of minor issues in the operating performance points
(OPP) framework and clean it up somewhat (Viresh Kumar).
- Fix a CONFIG dependency in the hibernation core and clean it up
slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
- Add rk3228 support to the rockchip-io adaptive voltage scaling
(AVS) driver (David Wu).
- Fix an incorrect bit shift operation in the RAPL power capping
driver (Adam Lessnau).
- Add support for the EPP field in the HWP (hardware managed
P-states) control register, HWP.EPP, to the x86_energy_perf_policy
tool and update msr-index.h with HWP.EPP values (Len Brown).
- Fix some minor issues in the turbostat tool (Len Brown).
- Add support for AMD family 0x17 CPUs to the cpupower tool and fix a
minor issue in it (Sherry Hurwitz).
- Assorted cleanups, mostly related to the constification of some
data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
Kozlowski)"

In hotplug logic, it always indicates non-specific failure to
platform through _OST when handing ACPI hot-remove event failed. Then
platform terminates the hot-remove process but it can not identify
the reason.
Base on current hot-remove code, there have two situations that it
returns busy:
- OSPM try to offline an individual device, but the device offline
function returns "busy".
- When the ejection event is applied to an "not offlined yet"
container. OSPM sends a kobject change event to userspace and
returns "busy".
Both of them will returns -EBUSY to ACPI device hotplug function.
Then, the hotplug function indicates non-specific failure to platform
just like for any other error, e.g. -ENODEV or -EIO.
The benefit to the platform for identifying the OS "busy" state is
that it can use a different approach to handle the "busy" instead of
simply terminating the hot-remove operation for an unknown reason.
For example, the platform can wait for a while and then re-trigger
hot-remove.

APM X-Gene verion 1 and 2 have an 8250 UART with its register
aligned to 32-bit. In addition, the latest released BIOS
encodes the access field as 8-bit access instead 32-bit access.
This causes no console with ACPI boot as the console
will not match X-Gene UART port due to the lack of mmio32
