      hpfs: implement the show_options method · 037369b8
      Mikulas Patocka authored
      The HPFS filesystem used generic_show_options to produce string that is
      displayed in /proc/mounts.  However, there is a problem that the options
      may disappear after remount.  If we mount the filesystem with option1
      and then remount it with option2, /proc/mounts should show both option1
      and option2, however it only shows option2 because the whole option
      string is replaced with replace_mount_options in hpfs_remount_fs.
      
      To fix this bug, implement the hpfs_show_options function that prints
      options that are currently selected.

      affs: fix remount failure when there are no options changed · 01d6e087
      Mikulas Patocka authored
      Commit c8f33d0b ("affs: kstrdup() memory handling") checks if the
      kstrdup function returns NULL due to out-of-memory condition.
      
      However, if we are remounting a filesystem with no change to
      filesystem-specific options, the parameter data is NULL.  In this case,
      kstrdup returns NULL (because it was passed NULL parameter), although no
      out of memory condition exists.  The mount syscall then fails with
      ENOMEM.
      
      This patch fixes the bug.  We fail with ENOMEM only if data is non-NULL.
      
      The patch also changes the call to replace_mount_options - if we didn't
      pass any filesystem-specific options, we don't call
      replace_mount_options (thus we don't erase existing reported options).

      Pull more MIPS updates from Ralf Baechle:
       "This is the secondnd batch of MIPS patches for 4.7. Summary:
      
        CPS:
         - Copy EVA configuration when starting secondary VPs.
      
        EIC:
         - Clear Status IPL.
      
        Lasat:
         - Fix a few off by one bugs.
      
        lib:
         - Mark intrinsics notrace.  Not only are the intrinsics
           uninteresting, it would cause infinite recursion.
      
        MAINTAINERS:
         - Add file patterns for MIPS BRCM device tree bindings.
         - Add file patterns for mips device tree bindings.
      
        MT7628:
         - Fix MT7628 pinmux typos.
         - wled_an pinmux gpio.
         - EPHY LEDs pinmux support.
      
        Pistachio:
         - Enable KASLR
      
        VDSO:
         - Build microMIPS VDSO for microMIPS kernels.
         - Fix aliasing warning by building with `-fno-strict-aliasing' for
           debugging but also tracing them might result in recursion.
      
        Misc:
         - Add missing FROZEN hotplug notifier transitions.
         - Fix clk binding example for varioius PIC32 devices.
         - Fix cpu interrupt controller node-names in the DT files.
         - Fix XPA CPU feature separation.
         - Fix write_gc0_* macros when writing zero.
         - Add inline asm encoding helpers.
         - Add missing VZ accessor microMIPS encodings.
         - Fix little endian microMIPS MSA encodings.
         - Add 64-bit HTW fields and fix its configuration.
         - Fix sigreturn via VDSO on microMIPS kernel.
         - Lots of typo fixes.
         - Add definitions of SegCtl registers and use them"
