A common way of multiplexing buttons on a single input in cheap devices is
to use a resistor ladder on an ADC. This driver supports that configuration

Input: mc13783_ts - remove deprecated create_singletheread_workqueue
The workqueue "workqueue" has a single workitem(&priv->work) and hence
doesn't require ordering. Also, it is not being used on a memory reclaim
path. Hence, the singlethreaded workqueue has been replaced with the use
of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Workitem is sync cancelled in mc13783_ts_remove() to ensure that there
are no workitems pending when the driver is disconnected.

Input: vmmouse - remove port reservation
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.
This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port
on its own.
The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs. It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

Input: xpad - fix oops when attaching an unknown Xbox One gamepad
Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.
This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.
This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.

Input: xpad - prevent spurious input from wired Xbox 360 controllers
After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.
Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.
Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.
The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03

arm64: bpf: jit JMP_JSET_{X,K}
Original implementation commit
e54bcde3d69d ("arm64: eBPF JIT compiler")
had the relevant code paths, but due to an oversight always fail jiting.
As a result, we had been falling back to BPF interpreter whenever a BPF
program has JMP_JSET_{X,K} instructions.
With this fix, we confirm that the corresponding tests in lib/test_bpf
continue to pass, and also jited.

net/route: enforce hoplimit max value
Currently, when creating or updating a route, no check is performed
in both ipv4 and ipv6 code to the hoplimit value.
The caller can i.e. set hoplimit to 256, and when such route will
be used, packets will be sent with hoplimit/ttl equal to 0.
This commit adds checks for the RTAX_HOPLIMIT value, in both ipv4
ipv6 route code, substituting any value greater than 255 with 255.
This is consistent with what is currently done for ADVMSS and MTU
in the ipv4 code.

nf_conntrack: avoid kernel pointer value leak in slab name
The slab name ends up being visible in the directory structure under
/sys, and even if you don't have access rights to the file you can see
the filenames.
Just use a 64-bit counter instead of the pointer to the 'net' structure
to generate a unique name.
This code will go away in 4.7 when the conntrack code moves to a single
kmemcache, but this is the backportable simple solution to avoiding
leaking kernel pointers to user space.
