compat_sys_x86_waitpid() is not needed, as it takes the same parameters
(int, *int, int) as the native syscall.

It is trivial to directly call _do_fork() instead of the sys_clone()
syscall in compat_sys_x86_clone().
This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see

sys_futex() is a wrapper to do_futex() which does not modify any
values here:
- uaddr, val and val3 are kept the same
- op is masked with FUTEX_CMD_MASK, but is always set to FUTEX_WAKE.
Therefore, val2 is always 0.
- as utime is set to NULL, *timeout is NULL

do_kexec_load() can be called directly by compat_sys_kexec() as long as
the same parameters checks are completed which are currently handled
(also) by sys_kexec(). Therefore, move those to kexec_load_check(),
call that newly introduced helper function from both sys_kexec() and
compat_sys_kexec(), and duplicate the remaining code from sys_kexec()
in compat_sys_kexec().

A similar but not fully equivalent code path is already open-coded
three times (in sys_rt_sigpending and in the two compat stubs), so
do it a fourth time here.

All call sites of sys_wait4() set *rusage to NULL. Therefore, there is
no need for the copy_to_user() handling of *rusage, and we can use
kernel_wait4() directly.

Pull perf updates from Ingo Molnar:
"The main kernel side changes were:
- Modernize the kprobe and uprobe creation/destruction tooling ABIs:
The existing text based APIs (kprobe_events and uprobe_events in
tracefs), are naive, limited ABIs in that they require user-space
to clean up after themselves, which is both difficult and fragile
if the tool is buggy or exits unexpectedly. In other words they are
not really suited for modern, robust tooling.
So introduce a modern, file descriptor based ABI that does not have
these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
PMUs and extend the perf_event_open() syscall to create events with
a kprobe/uprobe attached to them. These [k,u]probe are associated
with this file descriptor, so they are not available in tracefs.
(Song Liu)
- Intel Cannon Lake CPU support (Harry Pan)
- Intel PT cleanups (Alexander Shishkin)
- Improve the performance of pinned/flexible event groups by using RB
trees (Alexey Budankov)
- Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
of hardware breakpoints, which new ABI variant massively speeds up
existing tooling that uses hardware breakpoints to instrument (and
debug) memory usage.
(Milind Chabbi, Jiri Olsa)
- Various Intel PEBS handling fixes and improvements, and other Intel
PMU improvements (Kan Liang)
- Various perf core improvements and optimizations (Peter Zijlstra)
- ... misc cleanups, fixes and updates.
There's over 200 tooling commits, here's an (imperfect) list of
highlights:
- 'perf annotate' improvements:
* Recognize and handle jumps to other functions as calls, which
improves the navigation along jumps and back. (Arnaldo Carvalho
de Melo)
* Add the 'P' hotkey in TUI annotation to dump annotation output
into a file, to ease e-mail reporting of annotation details.
(Arnaldo Carvalho de Melo)
* Add an IPC/cycles column to the TUI (Jin Yao)
* Improve s390 assembly annotation (Thomas Richter)
* Refactor the output formatting logic to better separate it into
interactive and non-interactive features and add the --stdio2
output variant to demonstrate this. (Arnaldo Carvalho de Melo)
- 'perf script' improvements:
* Add Python 3 support (Jaroslav Škarvada)
* Add --show-round-event (Jiri Olsa)
- 'perf c2c' improvements:
* Add NUMA analysis support (Jiri Olsa)
- 'perf trace' improvements:
* Improve PowerPC support (Ravi Bangoria)
- 'perf inject' improvements:
* Integrate ARM CoreSight traces (Robert Walker)
- 'perf stat' improvements:
* Add the --interval-count option (yuzhoujian)
* Add the --timeout option (yuzhoujian)

- Vendor events improvements :
* Add IBM s390 vendor events (Thomas Richter)

Kulkarni)

- Intel PT tooling improvements (Adrian Hunter)

Pull locking updates from Ingo Molnar:
"The main changes in the locking subsystem in this cycle were:
- Add the Linux Kernel Memory Consistency Model (LKMM) subsystem,
which is an an array of tools in tools/memory-model/ that formally
describe the Linux memory coherency model (a.k.a.
Documentation/memory-barriers.txt), and also produce 'litmus tests'
in form of kernel code which can be directly executed and tested.
Here's a high level background article about an earlier version of
this work on LWN.net:
https://lwn.net/Articles/718628/
The design principles:
"There is reason to believe that Documentation/memory-barriers.txt
could use some help, and a major purpose of this patch is to
provide that help in the form of a design-time tool that can
produce all valid executions of a small fragment of concurrent
Linux-kernel code, which is called a "litmus test". This tool's
functionality is roughly similar to a full state-space search.
Please note that this is a design-time tool, not useful for
regression testing. However, we hope that the underlying
Linux-kernel memory model will be incorporated into other tools
capable of analyzing large bodies of code for regression-testing
purposes."
[...]
"A second tool is klitmus7, which converts litmus tests to
loadable kernel modules for direct testing. As with herd7, the
klitmus7 code is freely available from
http://diy.inria.fr/sources/index.html
(and via "git" at https://github.com/herd/herdtools7)"

net: mvneta: improve suspend/resume
This series tries to optimize the mvneta's suspend/resume
implementation by only taking necessary actions.
Since v2:
- keep rtnl lock when calling mvneta_start_dev() and mvneta_stop_dev()
Thank Russell for pointing this out
Since v1:
- unify ret check
- try best to keep the suspend/resume behavior
- split txq deinit into sw/hw parts as well
- adjust mvneta_stop_dev() location
I didn't add Thomas's Ack tag to patch1, because in v2, I add new code
to split the txq deinit into two parts.

Current suspend/resume implementation reuses the mvneta_open() and
mvneta_close(), but it could be optimized to take only necessary
actions during suspend/resume.
One obvious problem of current implementation is: after hundreds of
system suspend/resume cycles, the resume of mvneta could fail due to
fragmented dma coherent memory. After this patch, the non-necessary
memory alloc/free is optimized out.

This is to prepare the suspend/resume improvement in next patch. The
SW parts can be optimized out during resume.
As for rxq handling during suspend, we'd like to drop packets by
calling mvneta_rxq_drop_pkts() which is both SW and HW operation,
so we don't split rxq deinit.

A malicious user could force the directory pointer to be in an invalid
spot by using seekdir(2). Use the mechanism we already have to notice
if the directory has changed since the last time we called
ext4_readdir() to force a revalidation of the pointer.

====================
net: bgmac: Couple of sparse warnings
This patch series fixes a couple of warnings reported by sparse, should not
cause any functional problems since bgmac is typically used on LE platforms
anyway.

bgmac_dma_tx_ring_free() assigns the ctl1 word which is a litle endian
32-bit word without using proper accessors, fix this, and because a
length cannot be negative, use unsigned int while at it.

All the members: base, idm_base and nicpm_base should be annotated with
__iomem since they are pointers to register space. This fixes a bunch of
sparse reported warnings.

On RDMA errors, transport should disconnect the RDMA CM connection. This
will notify the upper layer, and it will attempt transport reconnect.

During transport reconnect, other processes may have registered memory
and blocked on transport. This creates a deadlock situation because the
transport resources can't be freed, and reconnect is blocked.
Fix this by returning to upper layer on timeout. Before returning,
transport status is set to reconnecting so other processes will release
memory registration resources.
Upper layer will retry the reconnect. This is not in fast I/O path so
setting the timeout to 5 seconds.

Change the following message (which can occur on reconnect) from
a warning to an FYI message. It is confusing to users.
[58360.523634] CIFS VFS: Free previous auth_key.response = 00000000a91cdc84
By default this message won't show up on reconnect unless the user bumps
up the log level to include FYI messages.

STATUS_FS_DRIVER_REQUIRED is expected when DFS is not turned
on on the server. Do not log it on DFS referral response.
It clutters the dmesg log unnecessarily at mount time.

We can not use the standard sg_set_buf() fucntion since when
CONFIG_DEBUG_SG=y this adds a check that will BUG_ON for cifs.ko
when we pass it an object from the stack.
Create a new wrapper smb2_sg_set_buf() which avoids doing that particular check
and use it for smb3 encryption instead.
