Both Dell Latitude machines were tested with new fan autodetection code and they
are working fine. We already have DMI_MATCH data for generic Latitude machines
which match also E6440 and E6540 models. So we do not need to maintain DMI data
for those specific machines anymore.

This patch adds new function i8k_get_fan_nominal_speed() for doing SMM call
which will return nominal fan RPM for specified fan speed. It returns nominal
RPM value at which fan operate when speed (0, 1, 2, 3) is set. It looks like
RPM value is not accurate, but still provides very useful information.
New function i8k_get_fan_nominal_speed() is used for determinate if fan
multiplier is 1 or 30. If function for maximal fan value success and returned
RPM value too high (above 30000) then fan multiplier is set to 1. Otherwise
multiplier is not changed and default value 30 is used.

Setting negative fan multiplier or maximal fan speed does make any sense and

Instead of returning a previous value if the SMM code returns
an error when trying to read a temperature, retry once.
If that fails again, return -ENODATA. Also return -ENODATA if an
attempt is made to read the GPU temperature but the GPU is
currently turned off.
Drop the I8K_TEMPERATURE_BUG definition and handle the related bug
unconditionally.

Detect presense of sensor by calling type function instead trying to read
temperature value. Type function is working also for sensors which are temporary
turned off (e.g on GPU which is turned off). Dell DOS binary NBSVC.MDM is doing
similar checks, so we should do that too.

We support memory hot-add in the Hyper-V balloon driver by hot adding an appropriately
sized and aligned region and controlling the on-lining of pages within that region
based on the pages that the host wants us to online. We do this because the
granularity and alignment requirements in Linux are different from what Windows
expects. The state to manage the onlining of pages needs to be correctly
protected. Fix this bug.

Make adjustments in computing the balloon floor. The current computation
of the balloon floor was not appropriate for virtual machines with more than
10 GB of assigned memory - we would get into situations where the host would
agressively balloon down the guest and leave the guest in an unusable state.
This patch fixes the issue by raising the floor.

Add security hooks to the binder and implement the hooks for SELinux.
The security hooks enable security modules such as SELinux to implement
controls over binder IPC. The security hooks include support for
controlling what process can become the binder context manager
(binder_set_context_mgr), controlling the ability of a process
to invoke a binder transaction/IPC to another process (binder_transaction),
controlling the ability of a process to transfer a binder reference to
another process (binder_transfer_binder), and controlling the ability
of a process to transfer an open file to another process (binder_transfer_file).
These hooks have been included in the Android kernel trees since Android 4.3.
(Updated to reflect upstream relocation and changes to the binder driver,
changes to the LSM audit data structures, coding style cleanups, and
to add inline documentation for the hooks).

The old implementation of sun9i_a80_get_pll4_factors() has several issues,
it checks against 256 / 512 in various places where it should use 255 / 511,
it does the wrong thing for low frequencies which are an even multiple of
6 MHz, e.g. if you ask it for 72 MHz it will result in 144 Mhz, and it does
not take into account that n must be at least 12. Moreover it is quite hard
to read / follow it.
This commit rewrites it to be correct in all cases, and makes it much easier
to follow the code / to read.

which is listed along with 04E6:000B in the Windows INF file for the
Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)".
The already-present quirk for 04E6:000B has USB_SC_SCSI/USB_PR_BULK, not
USB_SC_DEVICE/USB_PR_DEVICE. Change the 04E6:000F quirk to match that,

This device needs to be continuously clocked to provide wake up support,
previously, if STANDBY target were chosen the device were
enable_irq_wake()-prepared and clock still active and if MEM target were
chosen the device were also enable_irq_wake()-prepared but not clocked
anymore, which is wrong.
Now, if STANDBY target is chosen the device is still clocked with wake
up support enabled, which were the previous default and if MEM target is
chosen the device is declocked with wake up support disabled.
