Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver update for 4.14-rc1.
Lots of different stuff in here, it's been an active development cycle
for some reason. Highlights are:
- updated binder driver, this brings binder up to date with what
shipped in the Android O release, plus some more changes that
happened since then that are in the Android development trees.
- coresight updates and fixes
- mux driver file renames to be a bit "nicer"
- intel_th driver updates
- normal set of hyper-v updates and changes
- small fpga subsystem and driver updates
- lots of const code changes all over the driver trees
- extcon driver updates
- fmc driver subsystem upadates
- w1 subsystem minor reworks and new features and drivers added
- spmi driver updates
Plus a smattering of other minor driver updates and fixes.
All of these have been in linux-next with no reported issues for a
while"

added in 40304b2a15 ("bpf: BPF support for sock_ops") were added to

ends up triggering this warning when build tools/perf/:

So that we can build on older systems where otherwise we would end up
with:
CC /tmp/build/perf/trace/beauty/ioctl.o
trace/beauty/ioctl.c: In function 'ioctl__scnprintf_tty_cmd':
trace/beauty/ioctl.c:25:17: error: 'TIOCGEXCL' undeclared (first use in this function)
trace/beauty/ioctl.c:25:17: note: each undeclared identifier is reported only once for each function it appears in
trace/beauty/ioctl.c:25:2: error: array index in initializer not of integer type
trace/beauty/ioctl.c:25:2: error: (near initialization for 'ioctl_tty_cmd')
This way we can build a tool on an older system and it will still be
capable of processing perf.data files generated on newer systems.

It is often useful to know the branch types while analyzing branch data.
For example, a call is very different from a conditional branch.
Currently we have to look it up in binary while the binary may later not
be available and even the binary is available but user has to take some
time. It is very useful for user to check it directly in perf report.
Perf already has support for disassembling the branch instruction to get
the x86 branch type.
To keep consistent on kernel and userspace and make the classification
more common, the patch adds the common branch type classification
in perf_event.h.
The patch only defines a minimum but most common set of branch types.
PERF_BR_UNKNOWN : unknown
PERF_BR_COND ：conditional
PERF_BR_UNCOND : unconditional
PERF_BR_IND : indirect
PERF_BR_CALL : function call
PERF_BR_IND_CALL : indirect function call
PERF_BR_RET : function return
PERF_BR_SYSCALL : syscall
PERF_BR_SYSRET : syscall return
PERF_BR_COND_CALL : conditional function call
PERF_BR_COND_RET : conditional function return
The patch also adds a new field type (4 bits) in perf_branch_entry
to record the branch type.
Since the disassembling of branch instruction needs some overhead,
a new PERF_SAMPLE_BRANCH_TYPE_SAVE is introduced to indicate if it
needs to disassemble the branch instruction and record the branch
type.
Change log:
v10: Not changed.
v9: Not changed.
v8: Change PERF_BR_NONE to PERF_BR_UNKNOWN.
No other change.
v7: Just keep the most common branch types.
Others are removed.
v6: Not changed.
v5: Not changed. The v5 patch series just change the userspace.
v4: Comparing to previous version, the major changes are:
1. Remove the PERF_BR_JCC_FWD/PERF_BR_JCC_BWD, they will be
computed later in userspace.
2. Remove the "cross" field in perf_branch_entry. The cross page
computing will be done later in userspace.

To get the changes in the commit c75b1d9421 ("fs: add fcntl()
interface for setting/getting write life time hints").
Silencing this perf build warning:
Warning: include/uapi/linux/fcntl.h differs from kernel
We already beautify the fcntl cmd argument, so an upcoming cset will
update the 'cmd' strarray to cover these new commands.
The hints are in the 3rd arg, a pointer, so not yet supported in 'perf
trace', for that we need to copy it somehow, probably using eBPF, a new
attempt at doing that is planned.

This work adds a helper that can be used to adjust net room of an
skb. The helper is generic and can be further extended in future.
Main use case is for having a programmatic way to add/remove room to
v4/v6 header options along with cls_bpf on egress and ingress hook
of the data path. It reuses most of the infrastructure that we added
for the bpf_skb_change_type() helper which can be used in nat64
translations. Similarly, the helper only takes care of adjusting the
room so that related data is populated and csum adapted out of the
BPF program using it.
