d7b8943cf4 staging: pi433: rf69.c: Replace macros READ_REG and WRITE_REG with smarter functions
To increase the readability of the register accesses, the abstraction
of the helpers was increased from simple read and write to set bit,
clear bit and read modify write bit.

Annotation: This patch contains a lot of long lines and camel case
var names. These long lines and camel case vars weren't introduced
by this patch, but were long and camel cased before.

a05db75cfa staging: ccree: fix AEAD func naming convention
The aead files was using a func naming convention which was inconsistent
(ssi vs. cc), included a useless prefix (ssi_aead) and often used
too long function names producing monster func names such as
ssi_aead_gcm_setup_ghash_desc() that made the call site code hard
to read.

Make the code more readable by switching to a simpler, consistent naming
conventionfor all the function defined in the file.

b7ad7ef742 remove task and stack pointer printout from oops dump
Geert Uytterhoeven reported a NFS oops, and pointed out that some of the
numbers were hashed and useless.

We could just turn them from '%p' into '%px', but those numbers are
really just legacy, and useless even when not hashed.

So just remove them entirely.

8ee5ad1d4c arch/tile: mark as orphaned
The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox.  The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.

Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases.  In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.

Daniel Borkmann says:

====================
pull-request: bpf 2017-12-02

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a compilation warning in xdp redirect tracepoint due to
   missing bpf.h include that pulls in struct bpf_map, from Xie.

2) Limit the maximum number of attachable BPF progs for a given
   perf event as long as uabi is not frozen yet. The hard upper
   limit is now 64 and therefore the same as with BPF multi-prog
   for cgroups. Also add related error checking for the sample
   BPF loader when enabling and attaching to the perf event, from
   Yonghong.

3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log
   case, so that the test case can always pass and not fail in
   some environments due to too low default limit, also from
   Yonghong.

4) Fix up a missing license header comment for kernel/bpf/offload.c,
   from Jakub.

5) Several fixes for bpftool, among others a crash on incorrect
   arguments when json output is used, error message handling
   fixes on unknown options and proper destruction of json writer
   for some exit cases, all from Quentin.

First patch needs to be backported to kernels >= 3.18,

eeea10b83a tcp: add tcp_v4_fill_cb()/tcp_v4_restore_cb()
James Morris reported kernel stack corruption bug [1] while
running the SELinux testsuite, and bisected to a recent
commit bffa72cf7f ("net: sk_buff rbnode reorg")

We believe this commit is fine, but exposes an older bug.

SELinux code runs from tcp_filter() and might send an ICMP,
expecting IP options to be found in skb->cb[] using regular IPCB placement.

We need to defer TCP mangling of skb->cb[] after tcp_filter() calls.

This patch adds tcp_v4_fill_cb()/tcp_v4_restore_cb() in a very
similar way we added them for IPv6.

     devices.

 Major new features
 * at91-sama5d2-adc
   - DMA support including bindings + a fix for an issue with acking the
     interrupt to prevent false overrun reports.
 * ina2xx
   - allow control of shunt voltage PGA and bus voltage range to give better
     accuracy in some cases.
 * stm32-adc
   - support differential channels (precursor patch reworked how channel names
     were created to enable this).
 
 Cleanups / minor fixes / features
 * core
   - mark a deliberate switch fallthrough.
   - macro to populate struct iio_map array elements.
 * docs
   - typo fix.
 * MAINTAINERS
   - add some missing entries for IIO ABI files.
