96e0b2ba00 mmc: tmio: enhance illegal sequence handling
An illegal sequence command error may occur if there is a stopbit or
cmd_index error as well as a CRC error. The correct course of action
is to re-enable IRQs

An illegal sequence data error may occur if there is a CRC or stopbit
error,  or underrun. In this case set data->error correctly.

This is in preparation for enabling tuning support which relies on
differentiating between illegal sequence and other errors.

Therefore a new flag has been created that will allow 32-bit reads/writes

not supported).

8e8b3f514c mmc: core: use enum mmc_blk_status properly
There were several instances of code using the
enum mmc_blk_status by arbitrarily converting it to an int and
throwing it around to different functions. This makes the code
hard to understand to may give rise to strange errors.

Especially the function prototype mmc_start_req() had to be
modified to take a pointer to an enum mmc_blk_status and the
function pointer .err_check() inside struct mmc_async_req
needed to return an enum mmc_blk_status.

In every case: instead of assigning the block layer error code
to an int, use the enum, also change the signature of all
functions actually passing this enum to use the enum.

To make it possible to use the enum everywhere applicable, move
it to <linux/mmc/core.h> so that all code actually using it can
also see it.

An interesting case was encountered in the MMC test code which
did not return a enum mmc_blk_status at all in the .err_check
function supposed to check whether asynchronous requests worked
or not: instead it returned a normal -ERROR or even the test
frameworks internal error codes.

The test code would also pass on enum mmc_blk_status codes as
error codes inside the test code instead of converting them
to the local RESULT_* codes.

I have tried to fix all instances properly and run some tests
on the result.

49adc0cacb mmc: mmci: refactor ST Micro busy detection
The ST Micro-specific busy detection was made after the assumption
that only this variant supports busy detection. So when doing busy
detection, the host immediately tries to use some ST-specific
register bits.

Since the qualcomm variant also supports some busy detection
schemes, encapsulate the variant flags better in the variant struct
and prepare to add more variants by just providing some bitmasks
to the logic.

Put the entire busy detection logic within an if()-clause in the
mmci_cmd_irq() function so the code is only executed when busy
detection is enabled, and so that it is kept in (almost) one
place, and add comments describing what is going on so the
code can be understood.

Tested on the Ux500 by introducing some prints in the busy
detection path and noticing how the IRQ is enabled, used and
disabled successfully.

c2c24819b2 mmc: core: Don't power off the card when starting the host
The MMC_CAP2_NO_PRESCAN_POWERUP was invented to avoid running the power up
sequence, mmc_power_up(), during ->probe() of the mmc host driver, but
instead defer this to the mmc detect work. This is especially useful for
those hosts that suffers from a long initialization time, as this time
would otherwise add up to the total boot time.

However, due to the introduction of runtime PM of mmc host devices in the
mmc core, this behaviour changed a bit. More precisely, it caused the mmc
core to runtime resume the host device during ->probe() of the host driver.
In cases like the rtsx_usb_sdmmc, runtime resuming the device may be costly
and thus affecting the total boot time.

To improve this behaviour when using MMC_CAP2_NO_PRESCAN_POWERUP, let's
postpone also calling mmc_power_off() when starting the host. This change
allows the mmc core to avoid runtime resuming the device, as it don't need
to claim the host for that execution path.

70562644f4 mmc: core: Don't use ->card_busy() and CMD13 in combination when polling
When polling for busy after sending a MMC_SWITCH command, both the optional
->card_busy() callback and CMD13 are being used in conjunction.

This doesn't make sense. Instead it's more reasonable to rely solely on the
->card_busy() callback when it exists. Let's change that and instead use
the CMD13 as a fall-back. In this way we avoid sending CMD13, unless it's
really needed.

Within this context, let's also take the opportunity to make some
additional clean-ups and clarifications to the related code.

VMMC is an optional regulator, which means that mmc_regulator_get_supply
will only return an error in case of a deferred probe, but not when the
regulator is not set in the DT.

However, the sunxi driver assumes that VMMC is always there, and doesn't
check the value of the regulator pointer before using it, which obviously
leads to a (close to) null pointer dereference.

Add proper checks to prevent that.

30e2b7cfc5 Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams:

 - Fix a crash that occurs at driver initialization if the memory region
   is already busy (request_mem_region() fails).

 - Fix a vma validation check that mistakenly allows a private device-
   dax mapping to be established. Device-dax explicitly forbids private
   mappings so it can guarantee a given fault granularity and backing
   memory type.

 Both of these fixes have soaked in -next and are tagged for -stable.

e8f967c3d8 mvpp2: use correct size for memset
gcc-7 detects a short memset in mvpp2, introduced in the original
merge of the driver:

drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_cls_init':
drivers/net/ethernet/marvell/mvpp2.c:3296:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size]

The result seems to be that we write uninitialized data into the
flow table registers, although we did not get any warning about
that uninitialized data usage.

Using sizeof() lets us initialize then entire array instead.

97db8afa2a net: ethernet: mvneta: Remove IFF_UNICAST_FLT which is not implemented
The mvneta driver advertises it supports IFF_UNICAST_FLT. However, it
actually does not. The hardware probably does support it, but there is
no code to configure the filter. As a quick and simple fix, remove the
flag. This will cause the core to fall back to promiscuous mode.

beb53e4b23 ACPI fixes for v4.9-rc7
- Revert the recent commit that caused the ACPI _PTS method to
    be executed in the power-off/reboot code path (as per the
    specification) in an attempt to improve things on some systems
    (apparently expecting _PTS to be executed in that code path),
    but broke power-off/reboot on at least one other machine (Rafael
    Wysocki).
 
  - Fix kernel builds with the new WDAT watchdog driver enabled in
    some configurations by explicitly selecting WATCHDOG_CORE when
    enabling the WDAT watchdog driver (Mika Westerberg).

Merge tag 'acpi-4.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
 "Two ACPI fixes for 4.9-rc7.

  One of them reverts a recent ACPI commit that attempted to improve
  reboot/power-off on some systems, but introduced problems elsewhere,
  and the other one fixes kernel builds with the new WDAT watchdog
  driver enabled in some configurations.

  Specifics:

   - Revert the recent commit that caused the ACPI _PTS method to be
     executed in the power-off/reboot code path (as per the
     specification) in an attempt to improve things on some systems
     (apparently expecting _PTS to be executed in that code path), but

89119f0835 Revert "i2c: designware: do not disable adapter after transfer"
This reverts commit 0317e6c0f1.

Srinivas reported recently touchscreen and touchpad stopped working in
Haswell based machine in Linux 4.9-rc series with timeout errors from
i2c_designware:

[   16.508013] i2c_designware INT33C3:00: controller timed out
[   16.508302] i2c_hid i2c-MSFT0001:02: failed to change power setting.
[   17.532016] i2c_designware INT33C3:00: controller timed out
[   18.556022] i2c_designware INT33C3:00: controller timed out
[   18.556315] i2c_hid i2c-ATML1000:00: failed to retrieve report from device.

I managed to reproduce similar errors on another Haswell based machine
where touchscreen initialization fails maybe in every 1/5 - 1/2 boots.
Since root cause for these errors is not clear yet and debugging is
ongoing it's better to revert this commit as we are near to release.
