      usb: core: hub: Disable autosuspend for Cypress CY7C65632 · a7d8d1c7
      Andrew Lunn authored
      The Cypress CY7C65632 appears to have an issue with auto suspend and
      detecting devices, not too dissimilar to the SMSC 5534B hub. It is
      easiest to reproduce by connecting multiple mass storage devices to
      the hub at the same time. On a Lenovo Yoga, around 1 in 3 attempts
      result in the devices not being detected. It is however possible to
      make them appear using lsusb -v.
      
      Disabling autosuspend for this hub resolves the issue.

      i.MX8MM cannot detect certain CDP USB HUBs. usbmisc_imx.c driver is not
      following CDP timing requirements defined by USB BC 1.2 specification
      and section 3.2.4 Detection Timing CDP.
      
      During Primary Detection the i.MX device should turn on VDP_SRC and
      IDM_SINK for a minimum of 40ms (TVDPSRC_ON). After a time of TVDPSRC_ON,
      the i.MX is allowed to check the status of the D- line. Current
      implementation is waiting between 1ms and 2ms, and certain BC 1.2
      complaint USB HUBs cannot be detected. Increase delay to 40ms allowing
      enough time for primary detection.
      
      During secondary detection the i.MX is required to disable VDP_SRC and
      IDM_SNK, and enable VDM_SRC and IDP_SINK for at least 40ms (TVDMSRC_ON).
      
      Current implementation is not disabling VDP_SRC and IDM_SNK, introduce
      disable sequence in imx7d_charger_secondary_detection() function.
      
      VDM_SRC and IDP_SINK should be enabled for at least 40ms (TVDMSRC_ON).
      Increase delay allowing enough time for detection.

      usb: dwc3: core: fix kernel panic when do reboot · 4bf584a0
      Peter Chen authored
      When do system reboot, it calls dwc3_shutdown and the whole debugfs
      for dwc3 has removed first, when the gadget tries to do deinit, and
      remove debugfs for its endpoints, it meets NULL pointer dereference
      issue when call debugfs_lookup. Fix it by removing the whole dwc3
      debugfs later than dwc3_drd_exit.

      mm: relocate 'write_protect_seq' in struct mm_struct · 2e302543
      Feng Tang authored
      0day robot reported a 9.2% regression for will-it-scale mmap1 test
      case[1], caused by commit 57efa1fe ("mm/gup: prevent gup_fast from
      racing with COW during fork").
      
      Further debug shows the regression is due to that commit changes the
      offset of hot fields 'mmap_lock' inside structure 'mm_struct', thus some
      cache alignment changes.
      
      From the perf data, the contention for 'mmap_lock' is very severe and
      takes around 95% cpu cycles, and it is a rw_semaphore
      
              struct rw_semaphore {
                      atomic_long_t count;	/* 8 bytes */
                      atomic_long_t owner;	/* 8 bytes */
                      struct optimistic_spin_queue osq; /* spinner MCS lock */
                      ...
      
      Before commit 57efa1fe
      
       adds the 'write_protect_seq', it happens to
      have a very optimal cache alignment layout, as Linus explained:
      
       "and before the addition of the 'write_protect_seq' field, the
        mmap_sem was at offset 120 in 'struct mm_struct'.
      
        Which meant that count and owner were in two different cachelines,
        and then when you have contention and spend time in
        rwsem_down_write_slowpath(), this is probably *exactly* the kind
        of layout you want.
      
        Because first the rwsem_write_trylock() will do a cmpxchg on the
        first cacheline (for the optimistic fast-path), and then in the
        case of contention, rwsem_down_write_slowpath() will just access
        the second cacheline.
      
        Which is probably just optimal for a load that spends a lot of
        time contended - new waiters touch that first cacheline, and then
        they queue themselves up on the second cacheline."
      
      After the commit, the rw_semaphore is at offset 128, which means the
      'count' and 'owner' fields are now in the same cacheline, and causes
      more cache bouncing.
      
      Currently there are 3 "#ifdef CONFIG_XXX" before 'mmap_lock' which will
      affect its offset:
      
        CONFIG_MMU
        CONFIG_MEMBARRIER
        CONFIG_HAVE_ARCH_COMPAT_MMAP_BASES
      
      The layout above is on 64 bits system with 0day's default kernel config
      (similar to RHEL-8.3's config), in which all these 3 options are 'y'.
      And the layout can vary with different kernel configs.
      
      Relayouting a structure is usually a double-edged sword, as sometimes it
      can helps one case, but hurt other cases.  For this case, one solution
      is, as the newly added 'write_protect_seq' is a 4 bytes long seqcount_t
      (when CONFIG_DEBUG_LOCK_ALLOC=n), placing it into an existing 4 bytes
      hole in 'mm_struct' will not change other fields' alignment, while
      restoring the regression.

      block: loop: fix deadlock between open and remove · 990e7811
      Christoph Hellwig authored
      Commit c76f48eb
      
       ("block: take bd_mutex around delete_partitions in
      del_gendisk") adds disk->part0->bd_mutex in del_gendisk(), this way
      causes the following AB/BA deadlock between removing loop and opening
      loop:
      
       1) loop_control_ioctl(LOOP_CTL_REMOVE)
           -> mutex_lock(&loop_ctl_mutex)
           -> del_gendisk
               -> mutex_lock(&disk->part0->bd_mutex)
      
       2) blkdev_get_by_dev
           -> mutex_lock(&disk->part0->bd_mutex)
           -> lo_open
               -> mutex_lock(&loop_ctl_mutex)
      
      Add a new Lo_deleting state to remove the need for clearing
      ->private_data and thus holding loop_ctl_mutex in the ioctl
      LOOP_CTL_REMOVE path.

      x86, lto: Pass -stack-alignment only on LLD < 13.0.0 · 2398ce80
      Tor Vic authored
      
      
      Since LLVM commit 3787ee4, the '-stack-alignment' flag has been dropped
      [1], leading to the following error message when building a LTO kernel
      with Clang-13 and LLD-13:
      
          ld.lld: error: -plugin-opt=-: ld.lld: Unknown command line argument
          '-stack-alignment=8'.  Try 'ld.lld --help'
          ld.lld: Did you mean '--stackrealign=8'?
      
      It also appears that the '-code-model' flag is not necessary anymore
      starting with LLVM-9 [2].
      
      Drop '-code-model' and make '-stack-alignment' conditional on LLD < 13.0.0.
      
      These flags were necessary because these flags were not encoded in the
      IR properly, so the link would restart optimizations without them. Now
      there are properly encoded in the IR, and these flags exposing
      implementation details are no longer necessary.

      perf session: Correct buffer copying when peeking events · 197eecb6
      Leo Yan authored
      When peeking an event, it has a short path and a long path.  The short
      path uses the session pointer "one_mmap_addr" to directly fetch the
      event; and the long path needs to read out the event header and the
      following event data from file and fill into the buffer pointer passed
      through the argument "buf".
      
      The issue is in the long path that it copies the event header and event
      data into the same destination address which pointer "buf", this means
      the event header is overwritten.  We are just lucky to run into the
      short path in most cases, so we don't hit the issue in the long path.
      
      This patch adds the offset "hdr_sz" to the pointer "buf" when copying
      the event data, so that it can reserve the event header which can be
      used properly by its caller.

      Here are two fixes for the cp210x driver. The first fixes a regression
      with early revisions of the CP2102N which specifically broke some ESP32
      development boards. The second makes sure that the pin configuration is
      detected properly also for the CP2102N QFN20 package.
      
      Both have been in linux-next over night and with no reported issues.

      for now until it can be figured out properly.

      objtool: Only rewrite unconditional retpoline thunk calls · 2d49b721
      Peter Zijlstra authored
      It turns out that the compilers generate conditional branches to the
      retpoline thunks like:
      
        5d5:   0f 85 00 00 00 00       jne    5db <cpuidle_reflect+0x22>
      	5d7: R_X86_64_PLT32     __x86_indirect_thunk_r11-0x4
      
      while the rewrite can only handle JMP/CALL to the thunks. The result
      is the alternative wrecking the code. Make sure to skip writing the
      alternatives for conditional branches.
