      Revert "Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation" · 87916634
      Lyude Paul authored
      This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.
      
      Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
      works perfectly fine on the X1 Extreme Gen 2 except for one thing I
      didn't notice because I usually use the trackpoint: clicking with the
      touchpad. Somehow this is broken, in fact we don't even seem to indicate
      BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
      see any RMI4 events coming from the touchpad when I press down on it.
      This only seems to work for PS/2 mode.
      
      Since that means we have a regression, and PS/2 mode seems to work fine
      for the time being - revert this for now. We'll have to do a more
      thorough investigation on this.

      afs: Fix large file support · b485275f
      Marc Dionne authored
      By default s_maxbytes is set to MAX_NON_LFS, which limits the usable
      file size to 2GB, enforced by the vfs.
      
      Commit b9b1f8d5 ("AFS: write support fixes") added support for the
      64-bit fetch and store server operations, but did not change this value.
      As a result, attempts to write past the 2G mark result in EFBIG errors:
      
       $ dd if=/dev/zero of=foo bs=1M count=1 seek=2048
       dd: error writing 'foo': File too large
      
      Set s_maxbytes to MAX_LFS_FILESIZE.

      afs: Fix possible assert with callbacks from yfs servers · cd340703
      Marc Dionne authored
      Servers sending callback breaks to the YFS_CM_SERVICE service may
      send up to YFSCBMAX (1024) fids in a single RPC.  Anything over
      AFSCBMAX (50) will cause the assert in afs_break_callbacks to trigger.
      
      Remove the assert, as the count has already been checked against
      the appropriate max values in afs_deliver_cb_callback and
      afs_deliver_yfs_cb_callback.

      r8152: avoid to call napi_disable twice · 5b1d9c17
      Hayes Wang authored
      Call napi_disable() twice would cause dead lock. There are three situations
      may result in the issue.
      
      1. rtl8152_pre_reset() and set_carrier() are run at the same time.
      2. Call rtl8152_set_tunable() after rtl8152_close().
      3. Call rtl8152_set_ringparam() after rtl8152_close().
      
      For #1, use the same solution as commit 84811412 ("r8152: Re-order
      napi_disable in rtl8152_close"). For #2 and #3, add checking the flag
      of IFF_UP and using napi_disable/napi_enable during mutex.

      udp: drop skb extensions before marking skb stateless · 677bf08c
      Florian Westphal authored
      Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free
      assumes all skb head state has been dropped already.
      
      This will leak the extension memory in case the skb has extensions other
      than the ipsec secpath, e.g. bridge nf data.
      
      To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have
      extensions or if the extension space can be free'd.
      
      Fixes: 895b5c9f ("netfilter: drop bridge nf reset from nf_reset")

      net: rtnetlink: prevent underflows in do_setvfinfo() · ff08ddba
      Dan Carpenter authored
      The "ivm->vf" variable is a u32, but the problem is that a number of
      drivers cast it to an int and then forget to check for negatives.  An
      example of this is in the cxgb4 driver.

         - Two stability regression fixes for Raven
      
        i915:
         - Fix kernel oops on dumb_create ioctl on no crtc situation
         - Fix bad ugly colored flash on VLV/CHV related to gamma LUT update
         - Fix unity of the frequencies reported on PMU
         - Fix kernel oops on set_page_dirty using better locks around it
         - Protect the request pointer with RCU to prevent it being freed
           while we might need still
         - Make pool objects read-only
         - Restore physical addresses for fb_map to avoid corrupted page

      mm/ksm.c: don't WARN if page is still mapped in remove_stable_node() · 9a63236f
      Andrey Ryabinin authored
      It's possible to hit the WARN_ON_ONCE(page_mapped(page)) in
      remove_stable_node() when it races with __mmput() and squeezes in
      between ksm_exit() and exit_mmap().
      
        WARNING: CPU: 0 PID: 3295 at mm/ksm.c:888 remove_stable_node+0x10c/0x150

      Remove the warning as there is nothing scary going on.
