821ff38d19 ext4: keep uniform naming convention for io & io_end variables
Let's keep uniform naming convention for ext4_submit_io (io)
& ext4_end_io_t (io_end) structures, to avoid any confusion.
No functionality change in this patch.

044393a7b3 ARM: dts: mmp3: add Dell Wyse 3020 machine
This is a Dell Wyse thin client, variously referred to as "Ariel",
"3020" or "Tx0D" where "x" stands for the software it was shipped with.
I somewhat arbitrarily chose "ariel".

There are bits missing, because the drivers are not in and bindings are not
settled yet:

* Things missing from mmp3.dtsi:
  HSIC controller and its PHY (only the internal Ethernet is connected
  here, the hub with external USB2 ports is connected to the U2O controller
  that works well), Vivante GC2000 GPU

* &twsi1/regulator@19
  Marvell 88pm867 power regulator

* &twsi3/vga-dvi-encoder@76
  Chrontel CH7033B-BF VGA & DVI encoder

* &twsi3/sound-codec@30
  Sound chip, probably a Marvell 88ce156

* &twsi4/embedded-controller@58
  ENE KB3930QF Embedded Controller, also seems to be connected to &ssp4.
  Might not need a driver -- about the only useful thing it can do is to
  reboot the machine when tickled via some GPIO lines.

Also there seems to be something at &twsi1 address 0x50.

a9d21d1517 Actions Semi ARM64 changes for v5.5:
Most of the basic infrastructure is completed for the ARM64 S900 SoC.
 It can now boot a distro from eMMC/uSD with mainline kernel. Below are
 the changes for this cycle (only S900):
 
 - Added MMC controller support for S900 SoC. There are 4 controllers in
   this SoC, each capable of accessing MMC cards as well as SDIO.
 - Added onboard eMMC and uSD support for 96Boards Bubblegum96 board based
   on S900. Since the MMC driver is not capable of supporting SDIO currently,
   it is not enabled for now. And with the absence of PMIC support, fixed
   regulators are used to model the power supply.

e13a2fe642 tools/bpf: Turn on llvm alu32 attribute by default
LLVM alu32 was introduced in LLVM7:

  https://reviews.llvm.org/rL325987
  https://reviews.llvm.org/rL325989

Experiments showed that in general performance is better with alu32
enabled:

  https://lwn.net/Articles/775316/

This patch turns on alu32 with no-flavor test_progs which is tested
most often. The flavor test at no_alu32/test_progs can be used to
test without alu32 enabled. The Makefile check for whether LLVM
supports '-mattr=+alu32 -mcpu=v3' is removed as LLVM7 should be
available for recent distributions and also latest LLVM is preferred
to run BPF selftests.

Note that jmp32 is checked by -mcpu=probe and will be enabled if the
host kernel supports it.

2. If the lower netdevice is not a VLAN netdevice, consider tc mapping

88652bf8ce Merge branch 'r8169-remove-fiddling-with-the-pcie-max-read-request-size'
Heiner Kallweit says:

====================
The attempt to improve performance by changing the PCIe max read request
size was added in the vendor driver more than 10 years back and copied
to r8169 driver. In the vendor driver this has been removed long ago.
Obviously it had no effect, also in my tests I didn't see any
difference. Typically the max payload size is less than 512 bytes
anyway, and the PCI core takes care that the maximum supported value
is set. So let's remove fiddling with PCIe max read request size from
r8169 too. This change allows to simplify the driver in the subsequent
three patches of this series.

After further debugging it turns out that we walk kallsyms while in parallel
we tear down a BPF program which contains subprograms that have been JITed
though the program itself has not been fully exposed and is eventually bailing
out with error.

The bpf_prog_kallsyms_del_subprogs() in bpf_prog_load()'s error path removes
the symbols, however, bpf_prog_free() tears down the JIT memory too early via
scheduled work. Instead, it needs to properly respect RCU grace period as the
kallsyms walk for BPF is under RCU.

Fix it by refactoring __bpf_prog_put()'s tear down and reuse it in our error
path where we defer final destruction when we have subprogs in the program.

Fixes: 7d1982b4e3 ("bpf: fix panic in prog load calls cleanup")
Fixes: 1c2a088a66 ("bpf: x64: add JIT support for multi-function programs")

Ido Schimmel says:

====================
Vadim says:

This patch set extends the size of QSFP EEPROM for the cable types
SSF-8436 and SFF-8636 from 256 bytes to 640 bytes. This allows ethtool
to show correct information for these cable types (more details below).

Patch #1 adds a macro that computes the EEPROM page number from the
provided offset specified in the request.

Patch #2 teaches the driver to access the information stored in the
upper pages of the QSFP memory map.

Details and examples:

SFF-8436 specification defines pages 0, 1, 2 and 3. Page 0 contains
lower memory page offsets (from 0x00 to 0x7f) and upper page offsets
(from 0x80 to 0xfe). Upper pages 1, 2 and 3 are optional and can be
empty.

Page 1 is provided if upper page 0 byte 0xc3 bit 6 is set.
Page 2 is provided if upper page 0 byte 0xc3 bit 7 is set.
Page 3 is provided if lower page 0 byte 0x02 bit 2 is cleared.
Offset 0xc3 for the upper page is provided as 0x43 = 0xc3 - 0x80.

As a result of exposing 256 bytes only, ethtool shows wrong information
for pages 1, 2 and 3. In the below hex dump from ethtool for a cable
compliant to SFF-8636 specification, it can be seen that EEPROM of this
device contains optical diagnostic page (lower page 0 byte 0x02 bit 2 is
cleared), but it is not exposed, as the length defined for this type is
256 bytes.

After changing the length returned by get_module_info() callback from
256 bytes to 640 bytes, the upper pages 1, 2 and 3 are exposed by
ethtool. In the below hex dump from the same cable it can be seen that
the optical diagnostic page (page 3, from offset 0x0200) has non-zero
data.

ASoC: soc-pcm: fixup dpcm_prune_paths() loop continue
dpcm_prune_paths() is checking widget at 2 parts.

If we focus to (A) part, continue at (a) is for (1) loop. But,
if we focus to (B) part, continue at (b) is for (2) loop, not for (1).
This is bug.
This patch fixup this issue.

a9018adfde RDMA/uverbs: Prevent potential underflow
The issue is in drivers/infiniband/core/uverbs_std_types_cq.c in the
UVERBS_HANDLER(UVERBS_METHOD_CQ_CREATE) function.  We check that:

        if (attr.comp_vector >= attrs->ufile->device->num_comp_vectors) {

But we don't check if "attr.comp_vector" is negative.  It could
potentially lead to an array underflow.  My concern would be where
cq->vector is used in the create_cq() function from the cxgb4 driver.

And really "attr.comp_vector" is appears as a u32 to user space so that's
the right type to use.

a45bfb5a50 mlxsw: core: Extend QSFP EEPROM size for ethtool
Extend the size of QSFP EEPROM for the cable types SSF8436 and SFF8636
from 256 to 640 bytes in order to expose all the EEPROM pages by
ethtool.

For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes
of data for ethtool's get_module_eeprom() callback. This is because the
driver uses the below defines to specify SFF module length in ethtool's
get_module_info() callback:
'ETH_MODULE_SFF_8636_LEN' and 'ETH_MODULE_SFF_8436_LEN' (both are 256).

As a result of exposing 256 bytes only, ethtool shows wrong "zero" info
for pages 1, 2, 3.

The patch changes the length returned by callback for get_module_info()
to the values from the next defines: 'ETH_MODULE_SFF_8636_MAX_LEN' and
'ETH_MODULE_SFF_8436_MAX_LEN' (both are 640) to allow exposing of upper
page 1, 2 and 3.

a2aca4d7f0 Merge branch 'mlx5-rd-sgl' into rdma.git for-next
From Yamin Friedman:

====================
This series from Yamin implements long standing "TODO" existed in rw.c. It
allows the driver to specify a cut-over point where it is faster to build
a lkey MR rather than do a large SGL for RDMA READ operations.

mlx5 HW gets a notable performane boost by switching to MRs.
====================

Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies

* branch 'mlx5-rd-sgl': (3 commits)
  RDMA/mlx5: Add capability for max sge to get optimized performance
  RDMA/rw: Support threshold for registration vs scattering to local pages
  net/mlx5: Expose optimal performance scatter entries capability

366090564b RDMA/mlx5: Add capability for max sge to get optimized performance
Allows the IB device to provide a value of maximum scatter gather entries
per RDMA READ.

In certain cases it may be preferable for a device to perform UMR memory
registration rather than have many scatter entries in a single RDMA READ.
This provides a significant performance increase in devices capable of
using different memory registration schemes based on the number of scatter
gather entries. This general capability allows each device vendor to fine
tune when it is better to use memory registration.
