      Pull ARM SoC fixes from Arnd Bergmann:
 "Here are the latest bug fixes for ARM SoCs, mostly addressing recent
  regressions.  Changes are across several platforms, so I'm listing
  every change separately here.

  Regressions since 4.5:

   - A correction of the psci firmware DT binding, to prevent users from
     relying on unintended semantics

   - Actually getting the newly merged clock driver for some OMAP
     platforms to work

   - A revert of patches for the Qualcomm BAM, these need to be reworked
     for 4.7 to avoid breaking boards other than the one they were
     intended for

   - A correction for the I2C device nodes on the Socionext Uniphier
     platform

   - i.MX SDHCI was broken for non-DT platforms due to a change with the
     setting of the DMA mask

   - A revert of a patch that accidentally added a nonexisting clock on
     the Rensas "Porter" board

   - A couple of OMAP fixes that are all related to suspend after the
     power domain changes for dra7

   - On Mediatek, revert part of the power domain initialization changes
     that broke mt8173-evb

  Fixes for older bugs:

   - Workaround for an "external abort" in the omap34xx suspend/resume
     code.

   - The USB1/eSATA should not be listed as an excon device on
     am57xx-beagle-x15 (broken since v4.0)

   - A v4.5 regression in the TI AM33xx and AM43XX DT specifying
     incorrect DMA request lines for the GPMC

   - The jiffies calibration on Renesas platforms was incorrect for some
     modern CPU cores.

   - A hardware errata woraround for clockdomains on TI DRA7"

      devpts: more pty driver interface cleanups · 8ead9dd5
      由 Linus Torvalds 提交于 
      This is more prep-work for the upcoming pty changes.  Still just code
cleanup with no actual semantic changes.

This removes a bunch pointless complexity by just having the slave pty
side remember the dentry associated with the devpts slave rather than
the inode.  That allows us to remove all the "look up the dentry" code
for when we want to remove it again.

Together with moving the tty pointer from "inode->i_private" to
"dentry->d_fsdata" and getting rid of pointless inode locking, this
removes about 30 lines of code.  Not only is the end result smaller,
it's simpler and easier to understand.

The old code, for example, depended on the d_find_alias() to not just
find the dentry, but also to check that it is still hashed, which in
turn validated the tty pointer in the inode.

That is a _very_ roundabout way to say "invalidate the cached tty
pointer when the dentry is removed".

The new code just does

	dentry->d_fsdata = NULL;

in devpts_pty_kill() instead, invalidating the tty pointer rather more
directly and obviously.  Don't do something complex and subtle when the
obvious straightforward approach will do.

The rest of the patch (ie apart from code deletion and the above tty
pointer clearing) is just switching the calling convention to pass the
dentry or file pointer around instead of the inode.

      bpf: fix double-fdput in replace_map_fd_with_map_ptr() · 8358b02b
      由 Jann Horn 提交于 
      When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode
references a non-map file descriptor as a map file descriptor, the error
handling code called fdput() twice instead of once (in __bpf_map_get() and
in replace_map_fd_with_map_ptr()). If the file descriptor table of the
current task is shared, this causes f_count to be decremented too much,
allowing the struct file to be freed while it is still in use
(use-after-free). This can be exploited to gain root privileges by an
unprivileged user.

This bug was introduced in
commit 0246e64d ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only
exploitable since
commit 1be7f75d ("bpf: enable non-root eBPF programs") because
previously, CAP_SYS_ADMIN was required to reach the vulnerable code.

      sh_eth: use EDMR_SRST_GETHER in sh_eth_check_reset() · 97717edc
      由 Sergei Shtylyov 提交于 
      sh_eth_check_reset() uses a bare number where EDMR_SRST_GETHER would fit,
i.e. the receive/trasmit software reset bits that comprise EDMR_SRST_GETHER
read as 1  while the corresponding reset is in progress and thus, when both
are 0, the reset is complete.

====================
Mellanox 100G extending mlx5 ethtool support

Changes from V0:
	- Dropped: net/mlx5e: Disable link up on INIT HCA command
	  Due to Ido's and Or's requests we will submit this patch to net and will need it for -stable.
	- Rebased to: 11afbff8 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next")

This series is centralized around extending and improving mlx5 ethernet driver ethtool
support. We've done some code refactoring for ethtool statistics reporting, making it
more scalable and robust, now each reported ethtool counter belongs to a group and has
its own descriptor within that group, the descriptor holds the counter name and offset
in memory in that group memory block.

Added new counters:
	- Reporting more error and drop counter in ifconig/ip tool.
	- Per priority pause and traffic counter in ethtool.
	- link down events counter in ethtool.

Set features handling was also refactored a little bit to be more resilient and generic,
now setting more than one feature will not stop on the first failed one, but instead
it will try to continue setting others. We made it generic to make it simpler for adding
more features support, it is now done easily by only introducing a handler function of
the new supported netdev feature, and let the generic handler do the job.

New netdev features and ethtool support:
	- Netdev feature RXALL, set on/off FCS check offload.
	- Netdev feature HW_VLAN_CTAG_RX, set on/off rx-vlan stripping offload.
	- Ethtool interface identify.
	- Ethtool dump module EEPROM.
