Pull char/misc driver updates from Greg KH:
"Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level hardware
bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of the
crazy out-of-tree drivers that have been floating around for years,
combined with some really hacky userspace implementations. This is
only for GNSS receivers, but you have to start somewhere, and this
is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and
existing drivers.
All of these have been in linux-next for a while with no reported
issues"

As Ian pointed out, adding a '-' to the fallthrough seems to meet
the regex requirements at level 3 of the warning, at least when
the comment fits into a single line.
So, replace by a single line the comments that were broken into

The vivid driver uses a complex logic to save one kalloc/kfree
allocation. That non-trivial way of allocating data causes
smatch to warn:
drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'
drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'
I also needed to read the code several times in order to understand
what it was desired there. It turns that the logic was right,
although confusing to read.
As it is doing allocations on a non-standard way, let's add some
documentation while shutting up the false positive.

smatch warns that the RC query code could go past the array size:
drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1757 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130
drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1758 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130
The driver logic gets the length of the IR RX buffer with:
ret = rtl28xxu_rd_reg(d, IR_RX_BC, &buf[0]);
...
len = buf[0];
In thesis, this could range between 0 and 255 [1].
While this should never happen in practice, due to hardware limits,
smatch is right when it complains about that, as there's nothing at
the logic that would prevent it. So, if for whatever reason, buf[0]
gets filled by rtl28xx read functions with a value bigger than 128,
it will go past the array.
So, add an explicit check.
[1] I've no idea why smatch thinks that the maximum value is 130.
I double-checked the code several times. Was unable to find any
reason for assuming 130. Perhaps smatch is not properly parsing
u8 here?

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-08-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add cgroup local storage for BPF programs, which provides a fast
accessible memory for storing various per-cgroup data like number
of transmitted packets, etc, from Roman.
2) Support bpf_get_socket_cookie() BPF helper in several more program
types that have a full socket available, from Andrey.
3) Significantly improve the performance of perf events which are
reported from BPF offload. Also convert a couple of BPF AF_XDP
samples overto use libbpf, both from Jakub.
4) seg6local LWT provides the End.DT6 action, which allows to
decapsulate an outer IPv6 header containing a Segment Routing Header.
Adds this action now to the seg6local BPF interface, from Mathieu.
5) Do not mark dst register as unbounded in MOV64 instruction when
both src and dst register are the same, from Arthur.
6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier
instructions on arm64 for the AF_XDP sample code, from Brian.
7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts
over from Python 2 to Python 3, from Jeremy.
8) Enable BTF build flags to the BPF sample code Makefile, from Taeung.
9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee.
10) Several improvements to the README.rst from the BPF documentation
to make it more consistent with RST format, from Tobin.
11) Replace all occurrences of strerror() by calls to strerror_r()
in libbpf and fix a FORTIFY_SOURCE build error along with it,
from Thomas.
12) Fix a bug in bpftool's get_btf() function to correctly propagate
an error via PTR_ERR(), from Yue.

VSPD and VSP-DL devices can provide extended display lists supporting
extended command display list objects.
These extended commands require their own dma memory areas for a header
and body specific to the command type.
Implement a command pool to allocate all necessary memory in a single
DMA allocation to reduce pressure on the TLB, and provide convenient
re-usable command objects for the entities to utilise.

The kernel provides a __packed definition to abstract away from the
compiler specific attributes tag.
Convert all packed structures in VSP1 to use it.
The GCC documentation [0] describes this attribute as "the structure or
union is placed to minimize the memory required".
The Keil compiler documentation at [1] warns that the use of this
attribute can cause a performance penalty in the event that the compiler
can not deduce the allignment of each field.
Careful examination of the object code generated both with and without
this attribute shows that these structures are accessed identically and
are not affected by any performance penalty. The structures are
correctly aligned and padded to match the needs of the hardware already.
This patch does not serve to make a decision as to the use of the
attribute, but purely to clean up the code to use the kernel defined
abstraction as per [2].
