      net: smsc911x: back out silently on probe deferrals · ab4e4c07
      Linus Walleij authored
      When trying to get a regulator we may get deferred and we see
      this noise:
      
      smsc911x 1b800000.ethernet-ebi2 (unnamed net_device) (uninitialized):
         couldn't get regulators -517
      
      Then the driver continues anyway. Which means that the regulator
      may not be properly retrieved and reference counted, and may be
      switched off in case noone else is using it.
      
      Fix this by returning silently on deferred probe and let the
      system work it out.

      ibmveth: set correct gso_size and gso_type · 7b596738
      Thomas Falcon authored
      This patch is based on an earlier one submitted
      by Jon Maxwell with the following commit message:
      
      "We recently encountered a bug where a few customers using ibmveth on the
      same LPAR hit an issue where a TCP session hung when large receive was
      enabled. Closer analysis revealed that the session was stuck because the
      one side was advertising a zero window repeatedly.
      
      We narrowed this down to the fact the ibmveth driver did not set gso_size
      which is translated by TCP into the MSS later up the stack. The MSS is
      used to calculate the TCP window size and as that was abnormally large,
      it was calculating a zero window, even although the sockets receive buffer
      was completely empty."
      
      We rely on the Virtual I/O Server partition in a pseries
      environment to provide the MSS through the TCP header checksum
      field. The stipulation is that users should not disable checksum
      offloading if rx packet aggregation is enabled through VIOS.
      
      Some firmware offerings provide the MSS in the RX buffer.
      This is signalled by a bit in the RX queue descriptor.

      libata-scsi: disable SCT Write Same for the moment · e185934f
      Nicolai Stange authored
      SCT Write Same support had been introduced with
      commit 7b203094 ("libata: Add support for SCT Write Same")
      
      Some problems, namely excessive userspace segfaults, had been reported at
      
        http://lkml.kernel.org/r/20160908192736.GA4356@gmail.com
      
      This lead to commit 0ce1b18c ("libata: Some drives failing on
      SCT Write Same") which strived to disable SCT Write Same on !ZAC devices.
      Due to the way this was done and to the logic in sd_config_write_same(),
      this didn't work for those devices that have
      ->max_ws_blocks > SD_MAX_WS10_BLOCKS: for these, ->no_write_same and
      ->max_write_same_sectors would still be non-zero,
      but ->ws10 == ->ws16 == 0. This would cause sd_setup_write_same_cmnd() to
      demultiplex REQ_OP_WRITE_SAME requests to WRITE_SAME, and these in turn
      aren't supported by libata-scsi:
      
        EXT4-fs (dm-1): Delayed block allocation failed for inode 2625094 at
                        logical offset 2032 with max blocks 2 with error 121
        EXT4-fs (dm-1): This should not happen!! Data will be lost
      
      121 == EREMOTEIO is what scsi_io_completion() asserts in case of
      invalid opcodes.
      
      Back to the original problem of userspace segfaults: this can be tracked
      down to ata_format_sct_write_same() overwriting the input page. Sometimes,
      this page is ZERO_PAGE(0) which ceases to be filled with zeros from that
      point on. Since ZERO_PAGE(0) is used for userspace .bss mappings, code of
      the following is doomed:
      
        static char *a = NULL; /* .bss */
        ...
        if (a)
          *a = 'a';
      
      This problem is not solved by disabling SCT Write Same for !ZAC devices
      only.
      
      It can certainly be fixed, but the final release is quite close -- so
      disable SCT Write Same for all ATA devices rather than introducing some
      SCT key buffer allocation schemes at this point.

      ARM: dts: imx7d: fix LCDIF clock assignment · 4b707fa0
      Stefan Agner authored
      The eLCDIF IP of the i.MX 7 SoC knows multiple clocks and lists them
      separately:
      
      Clock      Clock Root              Description
      apb_clk    MAIN_AXI_CLK_ROOT       AXI clock
      pix_clk    LCDIF_PIXEL_CLK_ROOT    Pixel clock
      ipg_clk_s  MAIN_AXI_CLK_ROOT       Peripheral access clock
      
      All of them are switched by a single gate, which is part of the
      IMX7D_LCDIF_PIXEL_ROOT_CLK clock. Hence using that clock also for
      the AXI bus clock (clock-name "axi") makes sure the gate gets
      enabled when accessing registers.
      
      There seem to be no separate AXI display clock, and the clock is
      optional. Hence remove the dummy clock.
      
      This fixes kernel freezes when starting the X-Server (which
      disables/re-enables the display controller).
