        We've been hitting an early enospc problem on production machines that
        Omar tracked down to an old int->u64 mistake. I waited a bit on this
        pull to make sure it was really the problem from production, but it's
        on ~2100 hosts now and I think we're good.
      
        Omar also noticed a commit in the queue would make new early ENOSPC
        problems. I pulled that out for now, which is why the top three
        commits are younger than the rest.
      
        Otherwise these are all fixes, some explaining very old bugs that
        we've been poking at for a while"

      excessive checks in ufs_write_failed() and ufs_evict_inode() · babef37d
      Al Viro authored
      As it is, short copy in write() to append-only file will fail
      to truncate the excessive allocated blocks.  As the matter of
      fact, all checks in ufs_truncate_blocks() are either redundant
      or wrong for that caller.  As for the only other caller
      (ufs_evict_inode()), we only need the file type checks there.

      Btrfs: fix delalloc accounting leak caused by u32 overflow · 70e7af24
      Omar Sandoval authored
      btrfs_calc_trans_metadata_size() does an unsigned 32-bit multiplication,
      which can overflow if num_items >= 4 GB / (nodesize * BTRFS_MAX_LEVEL * 2).
      For a nodesize of 16kB, this overflow happens at 16k items. Usually,
      num_items is a small constant passed to btrfs_start_transaction(), but
      we also use btrfs_calc_trans_metadata_size() for metadata reservations
      for extent items in btrfs_delalloc_{reserve,release}_metadata().
      
      In drop_outstanding_extents(), num_items is calculated as
      inode->reserved_extents - inode->outstanding_extents. The difference
      between these two counters is usually small, but if many delalloc
      extents are reserved and then the outstanding extents are merged in
      btrfs_merge_extent_hook(), the difference can become large enough to
      overflow in btrfs_calc_trans_metadata_size().
      
      The overflow manifests itself as a leak of a multiple of 4 GB in
      delalloc_block_rsv and the metadata bytes_may_use counter. This in turn
      can cause early ENOSPC errors. Additionally, these WARN_ONs in
      extent-tree.c will be hit when unmounting:
      
          WARN_ON(fs_info->delalloc_block_rsv.size > 0);
          WARN_ON(fs_info->delalloc_block_rsv.reserved > 0);
          WARN_ON(space_info->bytes_pinned > 0 ||
                  space_info->bytes_reserved > 0 ||
                  space_info->bytes_may_use > 0);
      
      Fix it by casting nodesize to a u64 so that
      btrfs_calc_trans_metadata_size() does a full 64-bit multiplication.
      While we're here, do the same in btrfs_calc_trunc_metadata_size(); this
      can't overflow with any existing uses, but it's better to be safe here
      than have another hard-to-debug problem later on.

      Before this, we use 'filled' mode here, ie. if all range has been
      filled with EXTENT_DEFRAG bits, get to clear it, but if the defrag
      range joins the adjacent delalloc range, then we'll have EXTENT_DEFRAG
      bits in extent_state until releasing this inode's pages, and that
      prevents extent_data from being freed.
      
      This clears the bit if any was found within the ordered extent.

      In verify_dir_item, it wants to printk name_len of dir_item but
      printk data_len acutally.
      
      Fix it by calling btrfs_dir_name_len instead of btrfs_dir_data_len.

      Input: synaptics-rmi4 - register F03 port as pass-through serio · a0897d5f
      Dmitry Torokhov authored
      The 5th generation Thinkpad X1 Carbons use Synaptics touchpads accessible
      over SMBus/RMI, combined with ALPS or Elantech trackpoint devices instead
      of classic IBM/Lenovo trackpoints. Unfortunately there is no way for ALPS
      driver to detect whether it is dealing with touchpad + trackpoint
      combination or just a trackpoint, so we end up with a "phantom" dualpoint
      ALPS device in addition to real touchpad and trackpoint.
      
      Given that we do not have any special advanced handling for ALPS or
      Elantech trackpoints (unlike IBM trackpoints that have separate driver and
      a host of options) we are better off keeping the trackpoints in PS/2
      emulation mode. We achieve that by setting serio type to SERIO_PS_PSTHRU,
      which will limit number of protocols psmouse driver will try. In addition
      to getting rid of the "phantom" touchpads, this will also speed up probing
      of F03 pass-through port.

      efi: Fix boot panic because of invalid BGRT image address · 792ef14d

      Maniaxx reported a kernel boot crash in the EFI code, which I emulated
      by using same invalid phys addr in code:

         secondary_startup_64+0x9f/0x9f
      
      There is also a similar bug filed in bugzilla.kernel.org:
      
        https://bugzilla.kernel.org/show_bug.cgi?id=195633
      
      The crash is caused by this commit:
      
        7b0a9114 efi/x86: Move the EFI BGRT init code to early init code
      
      The root cause is the firmware on those machines provides invalid BGRT
      image addresses.
      
      In a kernel before above commit BGRT initializes late and uses ioremap()
      to map the image address. Ioremap validates the address, if it is not a
      valid physical address ioremap() just fails and returns. However in current
      kernel EFI BGRT initializes early and uses early_memremap() which does not
      validate the image address, and kernel panic happens.
      
      According to ACPI spec the BGRT image address should fall into
      EFI_BOOT_SERVICES_DATA, see the section 5.2.22.4 of below document:
      
        http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf
      
      Fix this issue by validating the image address in efi_bgrt_init(). If the
      image address does not fall into any EFI_BOOT_SERVICES_DATA areas we just
      bail out with a warning message.
