      net: smc91x: fix SMC accesses · 2fb04fdf
      Russell King authored
      Commit b70661c7 ("net: smc91x: use run-time configuration on all ARM
      machines") broke some ARM platforms through several mistakes.  Firstly,
      the access size must correspond to the following rule:
      
      (a) at least one of 16-bit or 8-bit access size must be supported
      (b) 32-bit accesses are optional, and may be enabled in addition to
          the above.
      
      Secondly, it provides no emulation of 16-bit accesses, instead blindly
      making 16-bit accesses even when the platform specifies that only 8-bit
      is supported.
      
      Reorganise smc91x.h so we can make use of the existing 16-bit access
      emulation already provided - if 16-bit accesses are supported, use
      16-bit accesses directly, otherwise if 8-bit accesses are supported,
      use the provided 16-bit access emulation.  If neither, BUG().  This
      exactly reflects the driver behaviour prior to the commit being fixed.
      
      Since the conversion incorrectly cut down the available access sizes on
      several platforms, we also need to go through every platform and fix up
      the overly-restrictive access size: Arnd assumed that if a platform can
      perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
      size needed to be specified - not so, all available access sizes must
      be specified.
      
      This likely fixes some performance regressions in doing this: if a
      platform does not support 8-bit accesses, 8-bit accesses have been
      emulated by performing a 16-bit read-modify-write access.
      
      Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
      accesses, which was broken by the original commit.

      net/mlx5e: Fix ethtool -g/G rx ring parameter report with striding RQ · cc8e9ebf
      Eran Ben Elisha authored
      The driver RQ has two possible configurations: striding RQ and
      non-striding RQ.  Until this patch, the driver always reported the
      number of hardware WQEs (ring descriptors). For non striding RQ
      configuration, this was OK since we have one WQE per pending packet
      For striding RQ, multiple packets can fit into one WQE. For better
      user experience we normalize the rx_pending parameter (size of wqe/mtu)
      as the average ring size in case of striding RQ.

      net/mlx5e: Limit UMR length to the device's limitation · fe4c988b
      Saeed Mahameed authored
      ConnectX-4 UMR (User Memory Region) MTT translation table offset in WQE
      is limited to U16_MAX, before this patch we ignored that limitation and
      requested the maximum possible UMR translation length that the netdev
      might need (MAX channels * MAX pages per channel).
      In case of a system with #cores > 32 and when linear WQE allocation fails,
      falling back to using UMR WQEs will cause the RQ (Receive Queue) to get
      stuck.
      
      Here we limit UMR length to min(U16_MAX, max required pages) (while
      considering the required alignments) on driver load, by default U16_MAX is
      sufficient since the default RX rings value guarantees that we are in
      range, dynamically (on set_ringparam/set_channels) we will check if the
      new required UMR length (num mtts) is still in range, if not, fail the
      request.

      powerpc: signals: Discard transaction state from signal frames · 78a3e888
      Cyril Bur authored
      Userspace can begin and suspend a transaction within the signal
      handler which means they might enter sys_rt_sigreturn() with the
      processor in suspended state.
      
      sys_rt_sigreturn() wants to restore process context (which may have
      been in a transaction before signal delivery). To do this it must
      restore TM SPRS. To achieve this, any transaction initiated within the
      signal frame must be discarded in order to be able to restore TM SPRs
      as TM SPRs can only be manipulated non-transactionally..

      It isn't clear exactly if there is really a use case for userspace
      returning with a suspended transaction, however, doing so doesn't (on
      its own) constitute a bad frame. As such, this patch simply discards
      the transactional state of the context calling the sigreturn and
      continues.

      powerpc/powernv : Drop reference added by kset_find_obj() · a9cbf0b2
      Mukesh Ojha authored
      In a situation, where Linux kernel gets notified about duplicate error log
      from OPAL, it is been observed that kernel fails to remove sysfs entries
      (/sys/firmware/opal/elog/0xXXXXXXXX) of such error logs. This is because,
      we currently search the error log/dump kobject in the kset list via
      'kset_find_obj()' routine. Which eventually increment the reference count
      by one, once it founds the kobject.
      
      So, unless we decrement the reference count by one after it found the kobject,
      we would not be able to release the kobject properly later.
      
      This patch adds the 'kobject_put()' which was missing earlier.

      tabort_syscall runs with RI=1, so a nested recoverable machine

      Mario Kleiner authored
      Due to assigning the 'replaced' value instead of or'ing it,
      if drm_atomic_crtc_set_property() gets called multiple times,
      the last call will define the color_mgmt_changed flag, so
      a non-updating call to a property can reset the flag and
      prevent actual hw state updates required by preceding
      property updates.
