       "These are mostly fixes and cleanups and removal of the no longer
        needed at32ap-cpufreq driver.
      
        Specifics:
      
         - Drop the at32ap-cpufreq driver which is useless after the removal
           of the corresponding arch (Corentin LABBE).
      
         - Fix a regression from the 4.14 cycle in the APM idle driver by
           making it initialize the polling state properly (Rafael Wysocki).
      
         - Fix a crash on failing system suspend due to a missing check in the
           cpufreq core (Bo Yan).
      
         - Make the intel_pstate driver initialize the hardware-managed
           P-state control (HWP) feature on CPU0 upon resume from system
           suspend if HWP had been enabled before the system was suspended
           (Chen Yu).
      
         - Fix up the SCPI cpufreq driver after recent changes (Sudeep Holla,
           Wei Yongjun).
      
         - Avoid pointer subtractions during frequency table walks in cpufreq
           (Dominik Brodowski).
      
         - Avoid the check for ProcFeedback in ST/CZ in the cpufreq driver for
           AMD processors and add a MODULE_ALIAS for cpufreq on ARM IMX (Akshu
           Agrawal, Nicolas Chauvet).
      
         - Fix the prototype of swsusp_arch_resume() on x86 (Arnd Bergmann).
      
         - Fix up the parsing of power domains DT data (Ulf Hansson)"

        Spectre v1 mitigation:

         - masking of the syscall number to restrict speculation through the
           syscall table

         - removing the current PSCI GET_VERSION firmware call mitigation as
           vendors are deploying new SMCCC-capable firmware

           and interrupts while in user mode
      
        Meltdown v3 mitigation update:
      
          - Cavium Thunder X is unaffected but a hardware erratum gets in the
            way. The kernel now starts with the page tables mapped as global
            and switches to non-global if kpti needs to be enabled.

      svcrdma: Fix Read chunk round-up · 175e0310
      Chuck Lever authored
      A single NFSv4 WRITE compound can often have three operations:
      PUTFH, WRITE, then GETATTR.
      
      When the WRITE payload is sent in a Read chunk, the client places
      the GETATTR in the inline part of the RPC/RDMA message, just after
      the WRITE operation (sans payload). The position value in the Read
      chunk enables the receiver to insert the Read chunk at the correct
      place in the received XDR stream; that is between the WRITE and
      GETATTR.
      
      According to RFC 8166, an NFS/RDMA client does not have to add XDR
      round-up to the Read chunk that carries the WRITE payload. The
      receiver adds XDR round-up padding if it is absent and the
      receiver's XDR decoder requires it to be present.
      
      Commit 193bcb7b ("svcrdma: Populate tail iovec when receiving")
      attempted to add support for receiving such a compound so that just
      the WRITE payload appears in rq_arg's page list, and the trailing
      GETATTR is placed in rq_arg's tail iovec. (TCP just strings the
      whole compound into the head iovec and page list, without regard
      to the alignment of the WRITE payload).
      
      The server transport logic also had to accommodate the optional XDR
      round-up of the Read chunk, which it did simply by lengthening the
      tail iovec when round-up was needed. This approach is adequate for
      the NFSv2 and NFSv3 WRITE decoders.
      
      Unfortunately it is not sufficient for nfsd4_decode_write. When the
      Read chunk length is a couple of bytes less than PAGE_SIZE, the
      computation at the end of nfsd4_decode_write allows argp->pagelen to
      go negative, which breaks the logic in read_buf that looks for the
      tail iovec.
      
      The result is that a WRITE operation whose payload length is just
      less than a multiple of a page succeeds, but the subsequent GETATTR
      in the same compound fails with NFS4ERR_OP_ILLEGAL because the XDR
      decoder can't find it. Clients ignore the error, but they must
      update their attribute cache via a separate round trip.
      
      As nfsd4_decode_write appears to expect the payload itself to always
      have appropriate XDR round-up, have svc_rdma_build_normal_read_chunk
      add the Read chunk XDR round-up to the page_len rather than
      lengthening the tail iovec.

      NFSD: hide unused svcxdr_dupstr() · 2285ae76
      Arnd Bergmann authored
      There is now only one caller left for svcxdr_dupstr() and this is inside
      of an #ifdef, so we can get a warning when the option is disabled:
      
      fs/nfsd/nfs4xdr.c:241:1: error: 'svcxdr_dupstr' defined but not used [-Werror=unused-function]
      
      This changes the remaining caller to use a nicer IS_ENABLED() check,
      which lets the compiler drop the unused code silently.

      nfsd: store stat times in fill_pre_wcc() instead of inode times · 39ca1bf6
      Amir Goldstein authored
      The time values in stat and inode may differ for overlayfs and stat time
      values are the correct ones to use. This is also consistent with the fact
      that fill_post_wcc() also stores stat time values.
      
      This means introducing a stat call that could fail, where previously we
      were just copying values out of the inode.  To be conservative about
      changing behavior, we fall back to copying values out of the inode in
      the error case.  It might be better just to clear fh_pre_saved (though
      note the BUG_ON in set_change_info).

      nfsd: encode stat->mtime for getattr instead of inode->i_mtime · 76c47948
      Amir Goldstein authored
      The values of stat->mtime and inode->i_mtime may differ for overlayfs
      and stat->mtime is the correct value to use when encoding getattr.
      This is also consistent with the fact that other attr times are also
      encoded from stat values.
      
      Both callers of lease_get_mtime() already have the value of stat->mtime,
      so the only needed change is that lease_get_mtime() will not overwrite
      this value with inode->i_mtime in case the inode does not have an
      exclusive lease.

      nfsd: return RESOURCE not GARBAGE_ARGS on too many ops · 0078117c
      J. Bruce Fields authored
      A client that sends more than a hundred ops in a single compound
      currently gets an rpc-level GARBAGE_ARGS error.
      
      It would be more helpful to return NFS4ERR_RESOURCE, since that gives
      the client a better idea how to recover (for example by splitting up the
      compound into smaller compounds).
      
      This is all a bit academic since we've never actually seen a reason for
      clients to send such long compounds, but we may as well fix it.
      
      While we're there, just use NFSD4_MAX_OPS_PER_COMPOUND == 16, the
      constant we already use in the 4.1 case, instead of hard-coding 100.
      Chances anyone actually uses even 16 ops per compound are small enough
      that I think there's a neglible risk or any regression.
      
      This fixes pynfs test COMP6.

        There's a few important fixes in here, mainly a fix for I/O on a
        number of devices caused by some of the component rework and a fix for
        a potential issue if more than one component in a link provides

      Merge tag 'riscv-for-linus-4.16-merge_window' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux
      
      Pull RISC-V updates from Palmer Dabbelt:
       "This contains the fixes we'd like to target for the 4.16 merge window.
        It's not as much as I was originally hoping to do but between glibc,
        the chip, and FOSDEM there just wasn't enough time to get everything
        put together. As such, this merge window is essentially just going to
        be small changes. This includes mostly cleanups:
      
         - A build fix failure to the audit test cases.
      
           RISC-V doesn't have renameat because the generic syscall ABI moved
           to renameat2 by the time of our port. The syscall audit test cases
           don't understand this, so I added a trivial fix. This went through
           mailing list review during the 4.15 merge window, but nobody has
           picked it up so I think it's best to just do this here.
      
         - The removal of our command-line argument processing code. The
           "mem_end" stuff was broken and the rest duplicated generic device
           tree code. The generic code was already being called.
      
         - Some unused/redundant code has been removed, including
           __ARCH_HAVE_MMU, current_pgdir, and the initialization of
           init_mm.pgd.
      
         - SUM is disabled upon taking a trap, which means that user memory is
           protected during traps taking inside copy_{to,from}_user().
      
         - The sptbr CSR has been renamed to satp in C code. We haven't
           changed the assembly code in order to maintain compatibility with
           binutils 2.29, which doesn't understand the new name.
      
        Additionally, we're adding some new features:
      
         - Basic ftrace support, thanks to Alan Kao!
      
         - Support for ZONE_DMA32.
      
           This is necessary for all the normal reasons, but also to deal with
           a deficiency in the Xilinx PCIe controller we're using on our
           FPGA-based systems. While the ZONE_DMA32 addition should be
           sufficient for most uses, it doesn't complete the fix for the
           Xilinx controller.
      
         - TLB shootdowns now only target the harts where they're necessary,
           instead of applying to all harts in the system.
      
        These patches have all been sitting on our linux-next branch for a
        while now. Due to time constraints this is all I feel comfortable
        submitting during the 4.16 merge window, hopefully we'll do better
        next time!"
      
      [ Note to self: "harts" is RISC-V speak for "hardware threads".  I had
        to look that up.    - Linus ]
