      pipe: fix empty pipe check in pipe_write() · 0dd1e377
      Jan Stancek authored
      LTP pipeio_1 test is hanging with v5.5-rc2-385-gb8e382a1,
      with read side observing empty pipe and sleeping and write
      side running out of space and then sleeping as well. In this
      scenario there are 5 writers and 1 reader.
      
      Problem is that after pipe_write() reacquires pipe lock, it
      re-checks for empty pipe with potentially stale 'head' and
      doesn't wake up read side anymore. pipe->tail can advance
      beyond 'head', because there are multiple writers.
      
      Use pipe->head for empty pipe check after reacquiring lock
      to observe current state.
      
      Testing: With patch, LTP pipeio_1 ran successfully in loop for 1 hour.
               Without patch it hanged within a minute.
      
      Fixes: 1b6b26ae ("pipe: fix and clarify pipe write wakeup logic")

      Pull io_uring fixes from Jens Axboe:
       "Here's a set of fixes that should go into 5.5-rc3 for io_uring.
      
        This is bigger than I'd like it to be, mainly because we're fixing the
        case where an application reuses sqe data right after issue. This
        really must work, or it's confusing. With 5.5 we're flagging us as
        submit stable for the actual data, this must also be the case for
        SQEs.
      
        Honestly, I'd really like to add another series on top of this, since
        it cleans it up considerable and prevents any SQE reuse by design. I
        posted that here:
      
          https://lore.kernel.org/io-uring/20191220174742.7449-1-axboe@kernel.dk/T/#u
      
        and may still send it your way early next week once it's been looked
        at and had some more soak time (does pass all regression tests). With
        that series, we've unified the prep+issue handling, and only the prep
        phase even has access to the SQE.
      
        Anyway, outside of that, fixes in here for a few other issues that
        have been hit in testing or production"

      Linus Torvalds authored
      Pull pin control fixes from Linus Walleij:
       "Sorry that this fixes pull request took a while. Too much christmas
        business going on.
      
        This contains a few really important Intel fixes and some odd fixes:
      
         - A host of fixes for the Intel baytrail and cherryview: properly
           serialize all register accesses and add the irqchip with the
           gpiochip as we need to, fix some pin lists and initialize the
           hardware in the right order.
      
         - Fix the Aspeed G6 LPC configuration.
      
         - Handle a possible NULL pointer exception in the core.
      
         - Fix the Kconfig dependencies for the Equilibrium driver"

      GPIO stuff on APUv4 seems to be the same as on APUv2, so we just
      need to match on DMI data.

      The CONNECT X300 uses the PMC clock for on-board components and gets
      stuck during boot if the clock is disabled. Therefore, add this
      device to the critical systems list.
      Tested on CONNECT X300.

      platform/x86: hp-wmi: Make buffer for HPWMI_FEATURE2_QUERY 128 bytes · 133b2ace
      Hans de Goede authored
      At least on the HP Envy x360 15-cp0xxx model the WMI interface
      for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes,
      otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS):
      
      Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5
      
      We do not care about the contents of the buffer, we just want to know
      if the HPWMI_FEATURE2_QUERY command is supported.
      
      This commits bumps the buffer size, fixing the error.

      platform/mellanox: fix the mlx-bootctl sysfs · 77dcc95e
      Liming Sun authored
      This is a follow-up commit for the sysfs attributes to change
      from DRIVER_ATTR to DEVICE_ATTR according to some initial comments.
      In such case, it's better to point the sysfs path to the device
      itself instead of the driver. The ABI document is also updated.

      xen/grant-table: remove multiple BUG_ON on gnttab_interface · d6bd6cf9
      Aditya Pakki authored
      gnttab_request_version() always sets the gnttab_interface variable
      and the assertions to check for empty gnttab_interface is unnecessary.
      The patch eliminates multiple such assertions.
