      This is introduced by commit a4a3ede2 ("mm: zero reserved and
      unavailable struct pages").
      
      The reason is some efi reserved boot ranges is not reported in E820 ram.
      In my case it is a bgrt buffer:
      
        efi: mem00: [Boot Data          |RUN|  |  |  |  |  |  |   |WB|WT|WC|UC] range=[0x00000000d2c41000-0x00000000d2c85fff] (0MB)
      
      Use "add_efi_memmap" can workaround the problem with another fix:
      
        http://lkml.kernel.org/r/20171130052327.GA3500@dhcp-128-65.nay.redhat.com
      
      In zero_resv_unavail it would be better to check pfn_valid first before
      zero the page struct.  This fixes the problem and potential other
      similar problems.  Also as Pavel Tatashin suggested checks pfn_valid at
      the beginning of the section.
      
      The range is backed by real memory.  The memory range is efi "Boot
      Service Data", that means after ExitBootServices() these ranges can be
      used as system ram.  But some of them need to be reserved, for example
      the bgrt image address in an acpi table, if the image memory is freed
      then kexec reboot will fail because kexec inherit same acpi table to
      initialize the driver.

       "Fixes this time include mostly device tree changes, as usual, the
        notable ones include:
      
         - A number of patches to fix most of the remaining DTC warnings that
           got introduced when DTC started warning about some obvious
           mistakes. We still have some remaining warnings that probably may
           have to wait until 4.16 to get fixed while we try to figure out
           what the correct contents should be.
      
         - On Allwinner A64, Ethernet PHYs need a fix after a mistake in
           coordination between patches merged through multiple branches.
      
         - Various fixes for PMICs on allwinner based boards
      
         - Two fixes for ethernet link detection on some Renesas machines
      
         - Two stability fixes for rockchip based boards
      
        Aside from device-tree, two other areas got fixes for older problems:
      
         - For TI Davinci DM365, a couple of fixes were needed to repair the
           MMC DMA engine support, apparently this has been broken for a
           while.
      
         - One important fix for all Allwinner chips with the PMIC driver as a
           loadable module"

      Merge tag 'sunxi-fixes-for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into fixes
      
      Pull "Allwinner fixes for 4.15" from Chen-Yu Tsai:
      
      First, one fix that adds proper regulator references for the EMAC
      external PHYs on A64 boards. The EMAC bindings were developed for 4.13,
      but reverted at the last minute. They were finalized and brought back
      for 4.15. However in the time between, regulator support for the A64
      boards was merged. When EMAC device tree changes were reintroduced,
      this was not taken into account.
      
      Second, a patch that adds OF based modalias uevent for RSB slave devices.
      This has been missing since the introduction of RSB, and recently with
      PMIC regulator support introduced for the A64, has been seen affecting
      distributions, which have the all-important PMIC mfd drivers built as
      modules, which then don't get loaded.
      
      Other minor cleanups include final conversion of raw indices to CCU
      binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the
      A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero
      Plus2, and adding a missing compatible for the PMIC on the TBS A711
      tablet.

      Pull "Renesas ARM Based SoC Fixes for v4.15" from Simon Horman:
      
      Vladimir Zapolskiy says:
      
      The present change is a bug fix for AVB link iteratively up/down.
      
      Steps to reproduce:
      - start AVB TX stream (Using aplay via MSE),
      - disconnect+reconnect the eth cable,
      - after a reconnection the eth connection goes iteratively up/down
        without user interaction,
      - this may heal after some seconds or even stay for minutes.
      
      As the documentation specifies, the "renesas,no-ether-link" option
      should be used when a board does not provide a proper AVB_LINK signal.
      There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS
      and ULCB starter kits since the AVB_LINK is correctly handled by HW.
      
      Choosing to keep or remove the "renesas,no-ether-link" option will
      have impact on the code flow in the following ways:
      - keeping this option enabled may lead to unexpected behavior since
        the RX & TX are enabled/disabled directly from adjust_link function
        without any HW interrogation,
      - removing this option, the RX & TX will only be enabled/disabled after
        HW interrogation. The HW check is made through the LMON pin in PSR
        register which specifies AVB_LINK signal value (0 - at low level;
        1 - at high level).
      
      In conclusion, the change is also a safety improvement because it
      removes the "renesas,no-ether-link" option leading to a proper way
      of detecting the link state based on HW interrogation and not on
      software heuristic.
      
      Note that DTS files for V3M Starter Kit, Draak and Eagle boards
      contain the same property, the files are untouched due to unavailable
      schematics to verify if the fix applies to these boards as well.

      afs: Fix unlink · 440fbc3a
      David Howells 提交于
      Repeating creation and deletion of a file on an afs mount will run the box
      out of memory, e.g.:
      
      	dd if=/dev/zero of=/afs/scratch/m0 bs=$((1024*1024)) count=512
      	rm /afs/scratch/m0
      
      The problem seems to be that it's not properly decrementing the nlink count
      so that the inode can be scrapped.
      
      Note that this doesn't fix local creation followed by remote deletion.
      That's harder to handle and will require a separate patch as we're not told
      that the file has been deleted - only that the directory has changed.

          error: uninitialized symbol 'remote_abort'.
      
      Smatch is right that "remote_abort" might be uninitialized when we pass
      it to afs_set_call_complete().  I don't know if that function uses the
      uninitialized variable.  Anyway, the comment for rxrpc_kernel_recv_data(),

      fscache: Fix the default for fscache_maybe_release_page() · 98801506
      David Howells 提交于
      Fix the default for fscache_maybe_release_page() for when the cookie isn't
      valid or the page isn't cached.  It mustn't return false as that indicates
      the page cannot yet be freed.
      
      The problem with the default is that if, say, there's no cache, but a
      network filesystem's pages are using up almost all the available memory, a
      system can OOM because the filesystem ->releasepage() op will not allow
      them to be released as fscache_maybe_release_page() incorrectly prevents
      it.
      
      This can be tested by writing a sequence of 512MiB files to an AFS mount.
      It does not affect NFS or CIFS because both of those wrap the call in a
      check of PG_fscache and it shouldn't bother Ceph as that only has
      PG_private set whilst writeback is in progress.  This might be an issue for
      9P, however.
      
      Note that the pages aren't entirely stuck.  Removing a file or unmounting
      will clear things because that uses ->invalidatepage() instead.

      capabilities: fix buffer overread on very short xattr · dc32b5c3

      If userspace attempted to set a "security.capability" xattr shorter than
      4 bytes (e.g. 'setfattr -n security.capability -v x file'), then
      cap_convert_nscap() read past the end of the buffer containing the xattr
      value because it accessed the ->magic_etc field without verifying that
      the xattr value is long enough to contain that field.
      
      Fix it by validating the xattr value size first.

      Pull irq fixes from Thomas Gleixner:
       "A rather large update after the kaisered maintainer finally found time
        to handle regression reports.
      
         - The larger part addresses a regression caused by the x86 vector
           management rework.
      
           The reservation based model does not work reliably for MSI
           interrupts, if they cannot be masked (yes, yet another hw
           engineering trainwreck). The reason is that the reservation mode
           assigns a dummy vector when the interrupt is allocated and switches
           to a real vector when the interrupt is requested.
      
           If the MSI entry cannot be masked then the initialization might
           raise an interrupt before the interrupt is requested, which ends up
           as spurious interrupt and causes device malfunction and worse. The
           fix is to exclude MSI interrupts which do not support masking from
           reservation mode and assign a real vector right away.
      
         - Extend the extra lockdep class setup for nested interrupts with a
           class for the recently added irq_desc::request_mutex so lockdep can
           differeniate and does not emit false positive warnings.
      
         - A ratelimit guard for the bad irq printout so in case a bad irq
           comes back immediately the system does not drown in dmesg spam"
