Here are some USB fixes for 4.15-rc4.
There is the usual handful gadget/dwc2/dwc3 fixes as always, for
reported issues. But the most important things in here is the core fix
from Alan Stern to resolve a nasty security bug (my first attempt is
reverted, Alan's was much cleaner), as well as a number of usbip fixes
from Shuah Khan to resolve those reported security issues.
All of these have been in linux-next with no reported issues.

At least on x86_64, the kernel's BPF selftests seemed to have stopped

While pulling in tools/arch/*/include/uapi/asm/bpf_perf_event.h seems
to work fine, there's no automated fall-back logic right now that would
do the same out of tools/include/uapi/asm-generic/bpf_perf_event.h. The
usual convention today is to add a include/[uapi/]asm/ equivalent that
would pull in the correct arch header or generic one as fall-back, all
ifdef'ed based on compiler target definition. It's similarly done also
in other cases such as tools/include/asm/barrier.h, thus adapt the same
here.

There are no longer any usersapce uses of ACCESS_ONCE(), so we can
remove the definition from our userspace <linux/compiler.h>, which is
only used by tools in the kernel directory (i.e. it isn't a uapi
header).
This patch removes the ACCESS_ONCE() definition, and updates comments
which referred to it. At the same time, some inconsistent and redundant
whitespace is removed from comments.

When a client has a USB device attached over IP, the vhci_hcd driver is
locally leaking a socket pointer address via the
/sys/devices/platform/vhci_hcd/status file (world-readable) and in debug
output when "usbip --debug port" is run.
Fix it to not leak. The socket pointer address is not used at the moment
and it was made visible as a convenient way to find IP address from socket
pointer address by looking up /proc/net/{tcp,tcp6}.
As this opens a security hole, the fix replaces socket pointer address with
sockfd.

Here are some small misc driver fixes for 4.15-rc3 to resolve reported
issues. Specifically these are:
- binder fix for a memory leak
- vpd driver fixes for a number of reported problems
- hyperv driver fix for memory accesses where it shouldn't be.
All of these have been in linux-next for a while. There's also one more
MAINTAINERS file update that came in today to get the Android
developer's emails correct, which is also in this pull request, that was
not in linux-next, but should not be an issue.

The regs_query_register_offset() helper function converts
register name like "%r0" to an offset of a register in user_pt_regs
It is required by the BPF prologue generator.
The user_pt_regs structure was recently added to "asm/ptrace.h".
Hence, update tools/perf/check-headers.sh to keep the header file
in sync with kernel changes.

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.

Programs and documentation not managed by package manager are generally
installed under /usr/local/, instead of the user's home directory. In
particular, `man` is generally able to find manual pages under
`/usr/local/share/man`.
bpftool generally follows perf's example, and perf installs to home
directory. However bpftool requires root credentials, so it seems
sensible to follow the more common convention of installing files under
/usr/local instead. So, make /usr/local the default prefix for
installing the binary with `make install`, and the documentation with
`make doc-install`. Also, create /usr/local/sbin if it does not exist.
Note that the bash-completion file, however, is still installed under
/usr/share/bash-completion/completions, as the default setup for bash
does not attempt to load completion files under /usr/local/.

If `getopt_long()` meets an unknown option, it prints its own error
message to standard error output. While this does not strictly break
JSON output, it is the only case bpftool prints something to standard
error output if JSON output is required. All other errors are printed on
standard output as JSON objects, so that an external program does not
have to parse stderr.
This is changed by setting the global variable `opterr` to 0.
Furthermore, p_err() is used to reproduce the error message in a more
JSON-friendly way, so that users still get to know what the erroneous
option is.

Test case 21 (Number of exit events of a simple workload) fails on
