Input: xpad - support some quirky Xbox One pads
There are several quirky Xbox One pads that depend on initialization
packets that the Microsoft pads don't require. To deal with these,
I've added a mechanism for issuing device-specific initialization
packets using a VID/PID-based quirks list.
For the initial set of init quirks, I have added quirk handling from
Valve's Steam Link xpad driver[0] and the 360Controller project[1] for
macOS to enable some new pads to work properly.
This should enable full functionality on the following quirky pads:
0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional)
0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional)
0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional)

"Al Viro reported that - in case of read faults - our copy_from_user()
implementation may claim to have copied more bytes than it actually

pa_memcpy() function with a pure assembler implementation.
While fixing the memcpy bug we noticed some other issues with our
get_user() and put_user() functions, e.g. nested faults may return
wrong data. This is now fixed by a common fixup handler for
get_user/put_user in the exception handler which additionally makes
generated code smaller and faster.
The third patch is a trivial one-line fix for a patch which went in
during 4.11-rc and which avoids stalled CPU warnings after power
shutdown (for parisc machines which can't plug power off themselves).
Due to the rewrite of pa_memcpy() into assembly this patch got bigger

Input: bma150 - remove support for bma150
This essentially reverts commit
baf28d91e7b1 ("Input: bma150 - avoid
binding to bma180 if IIO bma180 driver present") and commit
ef3714fdbc8d
("Input: bma150 - extend chip detection for bma180")
Rationale: initially (2012) the GTA04 device using a bma180 chip simply
referenced the bma150 platform driver in its board file [1] which happened
to work in all scenarios that were tested.
When conversion to DT started (2014), we needed to make the driver be still
recognised. Hence we introduced the compatibility to the bma180 chip in
Linux 3.15-rc5 [2] without further checks if it is really 100% compatible.
This worked flawlessly for years with the GTA04 device.
Recently (2016), Hans de Goede pointed out that the chips are not as
similar as they appeared and the driver works with the bma180 for the GTA04
only by good luck. He proposed to remove the bma180 support completely [3],
but we still did need it until we have a replacement. Thus, a conditional
compile was added.
We have now developed a generic iio-input-bridge which works with any 2 or
3 axis iio based accelerometer. It has been tested on GTA04 and Pyra and
works as expected. Therefore we can remove the bma180 support from this
driver completely. User-space API compatibility can be restored by using
the iio-input-bridge.
Maybe it is time to convert the bma150 driver to iio as well and retire the
accelerometer input drivers completely but this is a different story and
task.

bus notifiers use device type to distinguish between adapters and clients.
Previously we only had i2c_adapter_type exported, which made code wanting
to work with i2c_client devices test for type not equal to adapter type.
This unfortunately is not safe if we ever add another type to the bus,
so let's export i2c_client_type as well.

tty: pl011: fix earlycon work-around for QDF2400 erratum 44
The work-around for the Qualcomm Datacenter Technologies QDF2400
erratum 44 sets the "qdf2400_e44_present" global variable if the
work-around is needed. However, this check does not happen until after
earlycon is initialized, which means the work-around is not
used, and the console hangs as soon as it displays one character.

drivers/rapidio/devices/tsi721.c: make module parameter variable name unique
kbuild test robot reported a non-static variable name collision between
a staging driver and a RapidIO driver, with a generic variable name of
'dbg_level'.
Both drivers should be changed so that they don't use this generic
public variable name. This patch fixes the RapidIO driver but does not
change the user interface (name) for the module parameter.

mm/hugetlb.c: don't call region_abort if region_chg fails
Changes to hugetlbfs reservation maps is a two step process. The first
step is a call to region_chg to determine what needs to be changed, and
prepare that change. This should be followed by a call to call to
region_add to commit the change, or region_abort to abort the change.
The error path in hugetlb_reserve_pages called region_abort after a
failed call to region_chg. As a result, the adds_in_progress counter in
the reservation map is off by 1. This is caught by a VM_BUG_ON in
resv_map_release when the reservation map is freed.

kasan: report only the first error by default
Disable kasan after the first report. There are several reasons for
this:
- Single bug quite often has multiple invalid memory accesses causing
storm in the dmesg.
- Write OOB access might corrupt metadata so the next report will print
bogus alloc/free stacktraces.
- Reports after the first easily could be not bugs by itself but just
side effects of the first one.
Given that multiple reports usually only do harm, it makes sense to
disable kasan after the first one. If user wants to see all the
reports, the boot-time parameter kasan_multi_shot must be used.

hugetlbfs: initialize shared policy as part of inode allocation

mpol_free_shared_policy is unconditionally called as part of
