      Input: elants_i2c - do not clobber interrupt trigger on x86 · 4c83c071
      Dmitry Torokhov 提交于
      This is similar to commit a4b0a58b ("Input: elan_i2c - do not
      clobber interrupt trigger on x86")
      
      On x86 we historically used falling edge interrupts in the driver
      because that's how first Chrome devices were configured. They also
      did not use ACPI to enumerate I2C devices (because back then there
      was no kernel support for that), so trigger was hard-coded in the
      driver. However the controller behavior is much more reliable if
      we use level triggers, and that is how we configured ARM devices,
      and how want to configure newer x86 devices as well. All newer
      x86 boxes have their I2C devices enumerated in ACPI.
      
      Let's see if platform code (ACPI, DT) described interrupt and
      specified particular trigger type, and if so, let's use it instead
      of always clobbering trigger with IRQF_TRIGGER_FALLING. We will
      still use this trigger type as a fallback if platform code left
      interrupt trigger unconfigured.

      Revert "x86/mm: Stop calling leave_mm() in idle code" · 67535736
      Andy Lutomirski 提交于
      This reverts commit 43858b4f.
      
      The reason I removed the leave_mm() calls in question is because the
      heuristic wasn't needed after that patch.  With the original version
      of my PCID series, we never flushed a "lazy cpu" (i.e. a CPU running
      kernel thread) due a flush on the loaded mm.
      
      Unfortunately, that caused architectural issues, so now I've
      reinstated these flushes on non-PCID systems in:
      
          commit b956575b ("x86/mm: Flush more aggressively in lazy TLB mode").
      
      That, in turn, gives us a power management and occasionally
      performance regression as compared to old kernels: a process that
      goes into a deep idle state on a given CPU and gets its mm flushed
      due to activity on a different CPU will wake the idle CPU.
      
      Reinstate the old ugly heuristic: if a CPU goes into ACPI C3 or an
      intel_idle state that is likely to cause a TLB flush gets its mm
      switched to init_mm before going idle.
      
      FWIW, this heuristic is lousy.  Whether we should change CR3 before
      idle isn't a good hint except insofar as the performance hit is a bit
      lower if the TLB is getting flushed by the idle code anyway.  What we
      really want to know is whether we anticipate being idle long enough
      that the mm is likely to be flushed before we wake up.  This is more a
      matter of the expected latency than the idle state that gets chosen.
      This heuristic also completely fails on systems that don't know
      whether the TLB will be flushed (e.g. AMD systems?).  OTOH it may be a
      bit obsolete anyway -- PCID systems don't presently benefit from this
      heuristic at all.
      
      We also shouldn't do this callback from innermost bit of the idle code
      due to the RCU nastiness it causes.  All the information need is
      available before rcu_idle_enter() needs to happen.

      Input: sparse-keymap - send sync event for KE_SW/KE_VSW · 6f29c244
      Stefan Brüns 提交于
      Sync events are sent by sparse_keymap_report_entry for normal KEY_*
      events, and are generated by several drivers after generating
      SW_* events, so sparse_keymap_report_entry should do the same.
      
      Without the sync, events are accumulated in the kernel.
      
      Currently, no driver uses sparse-keymap for SW_* events, but
      it is required for the intel-vbtn platform driver to generate
      SW_TABLET_MODE events.

      Input: cyttsp4 - avoid overflows when calculating memory sizes · a2c714e8
      Vince Kim 提交于
      There are several places to perform subtraction to calculate buffer
      size such as:
      
      si->si_ofs.cydata_size = si->si_ofs.test_ofs - si->si_ofs.cydata_ofs;
      ...
      p = krealloc(si->si_ptrs.cydata, si->si_ofs.cydata_size, GFP_KERNEL);
      
      Actually, data types of above variables during subtraction are size_t, so
      it is unsigned. That means if second operand(si->si_ofs.cydata_ofs) is
      greater than the first operand(si->si_ofs.test_ofs), then resulting
      si->si_ofs.cydata_size could result in an unsigned integer wrap which is
      not desirable.
      
      The proper way to correct this problem is to perform a test of both
      operands to avoid having unsigned wrap.

      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      Greg Kroah-Hartman 提交于
      Many source files in the tree are missing licensing information, which
      makes it harder for compliance tools to determine the correct license.
      
      By default all files without license information are under the default
      license of the kernel, which is GPL version 2.
      
      Update the files which contain no license information with the 'GPL-2.0'
      SPDX license identifier.  The SPDX identifier is a legally binding
      shorthand, which can be used instead of the full boiler plate text.
      
      This patch is based on work done by Thomas Gleixner and Kate Stewart and
      Philippe Ombredanne.
      
      How this work was done:
      
      Patches were generated and checked against linux-4.14-rc6 for a subset of
      the use cases:
       - file had no licensing information it it.
       - file was a */uapi/* one with no licensing information in it,
       - file was a */uapi/* one with existing licensing information,
      
      Further patches will be generated in subsequent months to fix up cases
      where non-standard license headers were used, and references to license
      had to be inferred by heuristics based on keywords.
      
      The analysis to determine which SPDX License Identifier to be applied to
      a file was done in a spreadsheet of side by side results from of the
      output of two independent scanners (ScanCode & Windriver) producing SPDX
      tag:value files created by Philippe Ombredanne.  Philippe prepared the
      base worksheet, and did an initial spot review of a few 1000 files.
      
      The 4.13 kernel was the starting point of the analysis with 60,537 files
      assessed.  Kate Stewart did a file by file comparison of the scanner
      results in the spreadsheet to determine which SPDX license identifier(s)
      to be applied to the file. She confirmed any determination that was not
      immediately clear with lawyers working with the Linux Foundation.
      
      Criteria used to select files for SPDX license identifier tagging was:
       - Files considered eligible had to be source code files.
       - Make and config files were included as candidates if they contained >5
         lines of source
       - File already had some variant of a license header in it (even if <5
         lines).
      
      All documentation files were explicitly excluded.
      
      The following heuristics were used to determine which SPDX license
      identifiers to apply.
      
       - when both scanners couldn't find any license traces, file was
         considered to have no license information in it, and the top level
         COPYING file license applied.
      
         For non */uapi/* files that summary was:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|-------
         GPL-2.0                                              11139
      
         and resulted in the first patch in this series.
      
         If that file was a */uapi/* path one, it was "GPL-2.0 WITH
         Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|-------
         GPL-2.0 WITH Linux-syscall-note                        930
      
         and resulted in the second patch in this series.
      
       - if a file had some form of licensing information in it, and was one
         of the */uapi/* ones, it was denoted with the Linux-syscall-note if
         any GPL family license was found in the file or had no licensing in
         it (per prior point).  Results summary:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|------
         GPL-2.0 WITH Linux-syscall-note                       270
         GPL-2.0+ WITH Linux-syscall-note                      169
         ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
         ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
         LGPL-2.1+ WITH Linux-syscall-note                      15
         GPL-1.0+ WITH Linux-syscall-note                       14
         ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
         LGPL-2.0+ WITH Linux-syscall-note                       4
         LGPL-2.1 WITH Linux-syscall-note                        3
         ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
         ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1
      
         and that resulted in the third patch in this series.
      
       - when the two scanners agreed on the detected license(s), that became
         the concluded license(s).
      
       - when there was disagreement between the two scanners (one detected a
         license but the other didn't, or they both detected different
         licenses) a manual inspection of the file occurred.
      
       - In most cases a manual inspection of the information in the file
         resulted in a clear resolution of the license that should apply (and
         which scanner probably needed to revisit its heuristics).
      
       - When it was not immediately clear, the license identifier was
         confirmed with lawyers working with the Linux Foundation.
      
       - If there was any question as to the appropriate license identifier,
         the file was flagged for further research and to be revisited later
         in time.
      
      In total, over 70 hours of logged manual review was done on the
      spreadsheet to determine the SPDX license identifiers to apply to the
      source files by Kate, Philippe, Thomas and, in some cases, confirmation
      by lawyers working with the Linux Foundation.
      
      Kate also obtained a third independent scan of the 4.13 code base from
      FOSSology, and compared selected files where the other two scanners
      disagreed against that SPDX file, to see if there was new insights.  The
      Windriver scanner is based on an older version of FOSSology in part, so
      they are related.
      
      Thomas did random spot checks in about 500 files from the spreadsheets
      for the uapi headers and agreed with SPDX license identifier in the
      files he inspected. For the non-uapi files Thomas did random spot checks
      in about 15000 files.
      
      In initial set of patches against 4.14-rc6, 3 files were found to have
      copy/paste license identifier errors, and have been fixed to reflect the
      correct identifier.
      
      Additionally Philippe spent 10 hours this week doing a detailed manual
      inspection and review of the 12,461 patched files from the initial patch
      version early this week with:
       - a full scancode scan run, collecting the matched texts, detected
         license ids and scores
       - reviewing anything where there was a license detected (about 500+
         files) to ensure that the applied SPDX license was correct
       - reviewing anything where there was no detection but the patch license
         was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
         SPDX license was correct
      
      This produced a worksheet with 20 files needing minor correction.  This
      worksheet was then exported into 3 different .csv files for the
      different types of files to be modified.
      
      These .csv files were then reviewed by Greg.  Thomas wrote a script to
      parse the csv files and add the proper SPDX tag to the file, in the
      format that the file expected.  This script was further refined by Greg
      based on the output to detect more types of files automatically and to
      distinguish between header and source .c files (which need different
      comment types.)  Finally Greg ran the script using the .csv files to
      generate the patches.

      drm/i915: Check incoming alignment for unfenced buffers (on i915gm) · bb5cf338
      Chris Wilson 提交于
      In case the object has changed tiling between calls to execbuf, we need
      to check if the existing offset inside the GTT matches the new tiling
      constraint. We even need to do this for "unfenced" tiled objects, where
      the 3D commands use an implied fence and so the object still needs to
      match the physical fence restrictions on alignment (only required for
      gen2 and early gen3).
      
      In commit 2889caa9 ("drm/i915: Eliminate lots of iterations over
      the execobjects array"), the idea was to remove the second guessing and
      only set the NEEDS_MAP flag when required. However, the entire check
      for an unusable offset for fencing was removed and not just the
      secondary check. I.e.
      
      	/* avoid costly ping-pong once a batch bo ended up non-mappable */
              if (entry->flags & __EXEC_OBJECT_NEEDS_MAP &&

      ide:ide-cd: fix kernel panic resulting from missing scsi_req_init · 79d73346
      Hongxu Jia 提交于
      Since we split the scsi_request out of struct request, while the
      standard prep_rq_fn builds 10 byte cmds, it missed to invoke
      scsi_req_init() to initialize certain fields of a scsi_request
      structure (.__cmd[], .cmd, .cmd_len and .sense_len but no other
      members of struct scsi_request).
      
      An example panic on virtual machines (qemu/virtualbox) to boot
      from IDE cdrom:

      mmc: dw_mmc: Fix the DTO timeout calculation · 9d9491a7
      Douglas Anderson 提交于
      Just like the CTO timeout calculation introduced recently, the DTO
      timeout calculation was incorrect.  It used "bus_hz" but, as far as I
      can tell, it's supposed to use the card clock.  Let's account for the
      div value, which is documented as 2x the value stored in the register,
      or 1 if the register is 0.
      
      NOTE: This was likely not terribly important until commit 16a34574
      ("mmc: dw_mmc: remove the quirks flags") landed because "DIV" is
      documented on Rockchip SoCs (the ones that used to define the quirk)
      to always be 0 or 1.  ...and, in fact, it's documented to only be 1
      with EMMC in 8-bit DDR52 mode.  Thus before the quirk was applied to
      everyone it was mostly OK to ignore the DIV value.
      
      I haven't personally observed any problems that are fixed by this
      patch but I also haven't tested this anywhere with a DIV other an 0.
      AKA: this problem was found simply by code inspection and I have no
      failing test cases that are fixed by it.  Presumably this could fix
      real bugs for someone out there, though.

      mlxsw: reg: Add high and low temperature thresholds · 62b0e924
      Ido Schimmel 提交于
      The ASIC has the ability to generate events whenever a sensor indicates
      the temperature goes above or below its high or low thresholds,
      respectively.
      
      In new firmware versions the firmware enforces a minimum of 5
      degrees Celsius difference between both thresholds. Make the driver
      conform to this requirement.
      
      Note that this is required even when the events are disabled, as in
      certain systems interrupts are generated via GPIO based on these
      thresholds.
