Hans de Goede 8afb46804d i2c: designware: Cleanup bus lock handling
Now that most of the special Bay- / Cherry-Trail bus lock handling has
been moved to the iosf_mbi code we can simplify the remaining code a bit.

Hans de Goede 3c670dba86 ACPI / PMIC: xpower: Block P-Unit I2C access during read-modify-write
intel_xpower_pmic_update_power() does a read-modify-write of the output
control register. The i2c-designware code blocks the P-Unit I2C access
during the read and write by taking the P-Unit's PMIC bus semaphore.
But between the read and the write that semaphore is released and the
P-Unit could make changes to the register which we then end up overwriting.

This commit makes intel_xpower_pmic_update_power() take the semaphore
itself so that it is held over the entire read-modify-write, avoiding this
race.

Hans de Goede e09db3d241 x86: baytrail/cherrytrail: Rework and move P-Unit PMIC bus semaphore code
On some BYT/CHT systems the SoC's P-Unit shares the I2C bus with the
kernel. The P-Unit has a semaphore for the PMIC bus which we can take to
block it from accessing the shared bus while the kernel wants to access it.

Currently we have the I2C-controller driver acquiring and releasing the
semaphore around each I2C transfer. There are 2 problems with this:

1) PMIC accesses often come in the form of a read-modify-write on one of
the PMIC registers, we currently release the P-Unit's PMIC bus semaphore
between the read and the write. If the P-Unit modifies the register during
this window?, then we end up overwriting the P-Unit's changes.
I believe that this is mostly an academic problem, but I'm not sure.

2) To safely access the shared I2C bus, we need to do 3 things:
a) Notify the GPU driver that we are starting a window in which it may not
access the P-Unit, since the P-Unit seems to ignore the semaphore for
explicit power-level requests made by the GPU driver
b) Make a pm_qos request to force all CPU cores out of C6/C7 since entering
C6/C7 while we hold the semaphore hangs the SoC
c) Finally take the P-Unit's PMIC bus semaphore
All 3 these steps together are somewhat expensive, so ideally if we have
a bunch of i2c transfers grouped together we only do this once for the
entire group.

Taking the read-modify-write on a PMIC register as example then ideally we
would only do all 3 steps once at the beginning and undo all 3 steps once
at the end.

For this we need to be able to take the semaphore from within e.g. the PMIC
opregion driver, yet we do not want to remove the taking of the semaphore
from the I2C-controller driver, as that is still necessary to protect many
other code-paths leading to accessing the shared I2C bus.

This means that we first have the PMIC driver acquire the semaphore and
then have the I2C controller driver trying to acquire it again.

To make this possible this commit does the following:

1) Move the semaphore code from being private to the I2C controller driver
into the generic iosf_mbi code, which already has other code to deal with
the shared bus so that it can be accessed outside of the I2C bus driver.

2) Rework the code so that it can be called multiple times nested, while
still blocking I2C accesses while e.g. the GPU driver has indicated the
P-Unit needs the bus through a iosf_mbi_punit_acquire() call.

Merge tag 'libnvdimm-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:

 - Improve the efficiency and performance of reading nvdimm-namespace
   labels. Reduce the amount of label data read at driver load time by a
   few orders of magnitude. Reduce heavyweight call-outs to
   platform-firmware routines.

 - Handle media errors located in the 'struct page' array stored on a
   persistent memory namespace. Let the kernel clear these errors rather
   than an awkward userspace workaround.

 - Fix Address Range Scrub (ARS) completion tracking. Correct occasions
   where the kernel indicates completion of ARS before submission.

 - Fix asynchronous device registration reference counting.

 - Add support for reporting an nvdimm dirty-shutdown-count via sysfs.

 - Fix various small libnvdimm core and uapi issues.

Linus Torvalds d6edff78fe f2fs-for-4.20-rc1
In this round, we've added 1) superblock checksum feature, 2) implemented new
 mount option which we can disable/enable checkpoint to provide atomic updates of
 entire filesystem, 3) refactored quota operations to enhance its consistency
 along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward
 recovery flow to resurrect any fsync'ed inode metadata.
 
 Enhancement:
  - add checksum to keep superblock contents more safe
  - add checkpoint=disable/enable to support A/B update of entire filesystem
  - use plug for readahead IO in readdir
  - add more IO counts to avoid block layer hacks
 
 Bug fix:
  - prevent data corruption issue for hardware encryption
  - fix IO hang issues when GC is heavily triggered
  - add missing up_read in __write_node_page
  - recover inode metadata during roll-forward recovery flow
  - fix null pointer dereference issue in wrongly configured discard map
 
 There are some more sanity checks and minor bug fixes as well.

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've added 1) superblock checksum feature, 2)
  implemented new mount option which we can disable/enable checkpoint to
  provide atomic updates of entire filesystem, 3) refactored quota
  operations to enhance its consistency along with checkpoint, 4) fixed
  subtle IO hang conditions and roll-forward recovery flow to resurrect
  any fsync'ed inode metadata.

  Enhancements:
   - add checksum to keep superblock contents more safe
   - add checkpoint=disable/enable to support A/B update of entire filesystem
   - use plug for readahead IO in readdir
   - add more IO counts to avoid block layer hacks

  Bug fixes:
   - prevent data corruption issue for hardware encryption
   - fix IO hang issues when GC is heavily triggered
   - add missing up_read in __write_node_page
   - recover inode metadata during roll-forward recovery flow
   - fix null pointer dereference issue in wrongly configured discard map

  There are some more sanity checks and minor bug fixes as well"

Pul xfs updates from Dave Chinner:
 "There's not a huge amount of change in this cycle - Darrick has been
  out of action for a couple of months (hence me sending the last few
  pull requests), so we decided a quiet cycle mainly focussed on bug
  fixes was a good idea. Darrick will take the helm again at the end of
  this merge window.

  FYI, I may be sending another update later in the cycle - there's a
  pending rework of the clone/dedupe_file_range code that fixes numerous
  bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
  reviewed and tested, Al and I just need to work out the details of the
  merge, so it may come from him rather than me.

  Summary:

   - only support filesystems with unwritten extents

   - add definition for statfs XFS magic number

   - remove unused parameters around reflink code

   - more debug for dangling delalloc extents

   - cancel COW extents on extent swap targets

Pull btrfs updates from David Sterba:
 "This is the first batch with fixes and some nice performance
  improvements.

  Preliminary results show eg. more files/sec in fsmark, better perf on
  multi-threaded workloads (filebench, dbench), fewer context switches
  and overall better memory allocation characteristics (multiple
  benchmarks).

  Apart from general performance, there's an improvement for qgroups +
  balance workload that's been troubling our users.

  Note for stable: there are 20+ patches tagged for stable, out of 90.
  Not all of them apply cleanly on all stable versions but the conflicts
  are mostly due to simple cleanups and resolving should be obvious. The
  fixes are otherwise independent.

  Performance improvements:

   - transition between blocking and spinning modes of path is gone,
     which originally resulted to more unnecessary wakeups and updates
     to the path locks, the effects are measurable and improve latency
     and scalability

   - qgroups: first batch of changes that should speedup balancing with
     qgroups on, skip quota accounting on unchanged subtrees, overall
     gain is about 30+% in runtime

   - use rb-tree with cached first node for several structures, small
     improvement to avoid pointer chasing

  Fixes:

   - trim
      - fix: some blockgroups could have been missed if their logical
        address was past the total filesystem size (ie. after a lot of
        balancing)
      - better error reporting, after processing blockgroups and whole
        device
      - fix: continue trimming block groups after an error is
        encountered
      - check for trim support of the device earlier and avoid some
        unnecessary work
      - less interaction with transaction commit that improves latency
        on slower storage (eg. image files over NFS)

   - fsync
      - fix warning when replaying log after fsync of a O_TMPFILE
      - fix wrong dentries after fsync of file that got its parent
        replaced

   - qgroups: fix rescan that might misc some dirty groups

   - don't clean dirty pages during buffered writes, this could lead to
     lost updates in some corner cases

   - some block groups could have been delayed in creation, if the
     allocation triggered another one

   - error handling improvements

  Cleanups:

   - removed unused struct members and variables

   - function return type cleanups

   - delayed refs code refactoring

   - protect against deadlock that could be caused by crafted image that
     tries to allocate from a tree that's locked already"

Linus Torvalds ba9f6f8954 Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman:
 "I have been slowly sorting out siginfo and this is the culmination of
  that work.

  The primary result is in several ways the signal infrastructure has
  been made less error prone. The code has been updated so that manually
  specifying SEND_SIG_FORCED is never necessary. The conversion to the
  new siginfo sending functions is now complete, which makes it
  difficult to send a signal without filling in the proper siginfo
  fields.

  At the tail end of the patchset comes the optimization of decreasing
  the size of struct siginfo in the kernel from 128 bytes to about 48
  bytes on 64bit. The fundamental observation that enables this is by
  definition none of the known ways to use struct siginfo uses the extra
  bytes.

  This comes at the cost of a small user space observable difference.
  For the rare case of siginfo being injected into the kernel only what
  can be copied into kernel_siginfo is delivered to the destination, the
  rest of the bytes are set to 0. For cases where the signal and the
  si_code are known this is safe, because we know those bytes are not
  used. For cases where the signal and si_code combination is unknown
  the bits that won't fit into struct kernel_siginfo are tested to
  verify they are zero, and the send fails if they are not.

  I made an extensive search through userspace code and I could not find
  anything that would break because of the above change. If it turns out
  I did break something it will take just the revert of a single change
  to restore kernel_siginfo to the same size as userspace siginfo.

  Testing did reveal dependencies on preferring the signo passed to
  sigqueueinfo over si->signo, so bit the bullet and added the
  complexity necessary to handle that case.

  Testing also revealed bad things can happen if a negative signal
  number is passed into the system calls. Something no sane application
  will do but something a malicious program or a fuzzer might do. So I
  have fixed the code that performs the bounds checks to ensure negative
  signal numbers are handled"

Linus Torvalds a978a5b8d8 net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST
The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.

But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

As a result, a "make allmodconfig" complains

  WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS
    Depends on [n]: ARCH_QCOM && NET [=y]
    Selected by [m]:
    - ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM || COMPILE_TEST [=y])

Fix the config-time warning by making QCOM_QMI_HELPERS available when
COMPILE_TEST, since the result seems to build fine.

Eric Dumazet 3f80e08f40 tcp: add tcp_reset_xmit_timer() helper
With EDT model, SRTT no longer is inflated by pacing delays.

This means that RTO and some other xmit timers might be setup
incorrectly. This is particularly visible with either :

- Very small enforced pacing rates (SO_MAX_PACING_RATE)
- Reduced rto (from the default 200 ms)

This can lead to TCP flows aborts in the worst case,
or spurious retransmits in other cases.

For example, this session gets far more throughput
than the requested 80kbit :

$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

540000 262144 262144    104.00      2.66

With the fix :

$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

540000 262144 262144    104.00      0.12

EDT allows for better control of rtx timers, since TCP has
a better idea of the earliest departure time of each skb
in the rtx queue. We only have to eventually add to the
timer the difference of the EDT time with current time.

Ivan Vecera 5ef79151c2 Revert "be2net: remove desc field from be_eq_obj"
The mentioned commit needs to be reverted because we cannot pass
string allocated on stack to request_irq(). This function stores
uses this pointer for later use (e.g. /proc/interrupts) so we need
to keep this string persistently.

Karsten Graul 89ab066d42 Revert "net: simplify sock_poll_wait"
This reverts commit dd979b4df8.

This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an
internal TCP socket for the initial handshake with the remote peer.
Whenever the SMC connection can not be established this TCP socket is
used as a fallback. All socket operations on the SMC socket are then
forwarded to the TCP socket. In case of poll, the file->private_data
pointer references the SMC socket because the TCP socket has no file
assigned. This causes tcp_poll to wait on the wrong socket.

Masahisa Kojima 8d5b0bf611 net: socionext: Reset tx queue in ndo_stop
We observed that packets and bytes count are not reset
when user performs interface down. Eventually, tx queue is
exhausted and packets will not be sent out.
To avoid this problem, resets tx queue in ndo_stop.
