      s390/kasan: increase instrumented stack size to 64k · 9fed920e
      Vasily Gorbik authored
      Increase kasan instrumented kernel stack size from 32k to 64k. Other
      architectures seems to get away with just doubling kernel stack size under
      kasan, but on s390 this appears to be not enough due to bigger frame size.
      The particular pain point is kasan inlined checks (CONFIG_KASAN_INLINE
      vs CONFIG_KASAN_OUTLINE). With inlined checks one particular case hitting
      stack overflow is fs sync on xfs filesystem:

      s390/cpum_sf: Rework attribute definition for diagnostic sampling · c43e1c5a
      Thomas Richter authored
      Previously, the attribute entry for diagnostic sampling was added
      if authorized.  Otherwise, the array of struct attribute contains
      two NULL values.
      
      Change this logic and reserve space for the attribute for diagnostic
      sampling. If diagnostic sampling is authorized, add an entry in the
      respective position in the array of struct attribute.

      s390/mm: fix mis-accounting of pgtable_bytes · e12e4044
      Martin Schwidefsky authored
      In case a fork or a clone system fails in copy_process and the error
      handling does the mmput() at the bad_fork_cleanup_mm label, the
      following warning messages will appear on the console:
      
        BUG: non-zero pgtables_bytes on freeing mm: 16384
      
      The reason for that is the tricks we play with mm_inc_nr_puds() and
      mm_inc_nr_pmds() in init_new_context().
      
      A normal 64-bit process has 3 levels of page table, the p4d level and
      the pud level are folded. On process termination the free_pud_range()
      function in mm/memory.c will subtract 16KB from pgtable_bytes with a
      mm_dec_nr_puds() call, but there actually is not really a pud table.
      
      One issue with this is the fact that pgtable_bytes is usually off
      by a few kilobytes, but the more severe problem is that for a failed
      fork or clone the free_pgtables() function is not called. In this case
      there is no mm_dec_nr_puds() or mm_dec_nr_pmds() that go together with
      the mm_inc_nr_puds() and mm_inc_nr_pmds in init_new_context().
      The pgtable_bytes will be off by 16384 or 32768 bytes and we get the
      BUG message. The message itself is purely cosmetic, but annoying.
      
      To fix this override the mm_pmd_folded, mm_pud_folded and mm_p4d_folded
      function to check for the true size of the address space.

      mm: add mm_pxd_folded checks to pgtable_bytes accounting functions · 6d212db1
      Martin Schwidefsky authored
      The common mm code calls mm_dec_nr_pmds() and mm_dec_nr_puds()
      in free_pgtables() if the address range spans a full pud or pmd.
      If mm_dec_nr_puds/mm_dec_nr_pmds are non-empty due to configuration
      settings they blindly subtract the size of the pmd or pud table from
      pgtable_bytes even if the pud or pmd page table layer is folded.
      
      Add explicit mm_[pmd|pud]_folded checks to the four pgtable_bytes
      accounting functions mm_inc_nr_puds, mm_inc_nr_pmds, mm_dec_nr_puds
      and mm_dec_nr_pmds. As the check for folded page tables can be
      overwritten by the architecture, this allows to keep a correct
      pgtable_bytes value for platforms that use a dynamic number of
      page table levels.

      s390: avoid vmlinux segments overlap · 5a2e1853
      Vasily Gorbik authored
      Currently .vmlinux.info section of uncompressed vmlinux elf image is
      included into the data segment and load address specified as 0. That
      extends data segment to address 0 and makes "text" and "data" segments
      overlap.

         02     .notes
      
      Later when vmlinux.bin is produced from vmlinux, .vmlinux.info section
      is removed. But elf vmlinux file, even though it is not bootable anymore,
      used for debugging and loadable segments overlap should be avoided.
      
      Utilize special ":NONE" phdr specification to avoid adding .vmlinux.info
      into loadable data segment. Also set .vmlinux.info section type to INFO,
      which allows to get a not-loadable info CONTENTS section.
      
      Since minimal supported version of binutils 2.20 does not have
      --dump-section objcopy option, make .vmlinux.info section loadable during
      info.bin creation to get actual section contents.

         - On systems with F but without D the kernel will not show the F
           extension to userspace, as it isn't actually supported.
      
         - Support for futexes.
      
         - Removal of some unused code.
      
         - Cleanup of some menuconfig entries.
      
         - Support for systems without a floating-point unit, and for building
           kernels that will never use the floating-point unit.
      
         - More fixes to the RV32I port, which regressed again. It's really
           time to get this into a regression test somewhere so I stop
           breaking it. Thanks to Zong for resurrecting it again!
      
         - Various fixes that resulted from a year old review of our original
           patch set that I finally got around to.
      
         - Various improvements to SMP support, largely based around having
           switched to logical hart numbering, as well as some interrupt
           improvements. This one is in the same patch set as above, thanks to
           Atish for sheparding everything though as my patch set was a bit of
           a mess.
      
        I'm pretty sure this is our largest patch set since the original
        kernel contribution, and it's certainly the one with the most
        contributors. While I don't have anything else I know I'm going to
        submit for the merge window, I would be somewhat surprised if I didn't

      sparc: Fix VDSO build with older binutils. · caf539cd
      David S. Miller authored
      Older versions of bintutils do not allow symbol math across different
      segments on sparc:
      
      ====================
      Assembler messages:
      99: Error: operation combines symbols in different segments
      ====================
      
      This is controlled by whether or not DIFF_EXPR_OK is defined in
      gas/config/tc-*.h and for sparc this was not the case until mid-2017.
      
      So we have to patch between %stick and %tick another way.
      
      Do what powerpc does and emit two versions of the relevant functions,
      one using %tick and one using %stick, and patch the symbols in the
      dynamic symbol table.
      
      Fixes: 2f6c9bf3 ("sparc: Improve VDSO instruction patching.")

        highlights:
      
        General:
        - Appropriate fall-through annotations everywhere
        - Some code cleanup in memalloc code, handling non-cacahed pages more

        - More HD-audio CA0132 codec improvement for supporting other Creative
          boards
        - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
          give move support of existing HD-audio devices with DSP
        - A few device-specific HD-audio quirks as usual
        - New quirk for RME CC devices and correction for B&W PX for USB-audio
        - FireWire: code refactoring including devres usages
      
        ASoC Core:
        - Continued componentization works; it's almost done!
        - A bunch of new for_each_foo macros
        - Cleanups and fixes in DAPM code
      
        ASoC Drivers:
        - MCLK support for several different devices, including CS42L51, STM32
          SAI, and MAX98373
        - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and

      Pull SCSI updates from James Bottomley:
       "This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
        qla2xxx, lpfc, libsas, hisi_sas.
      
        In addition there's a set of mostly small updates to the target
        subsystem a set of conversions to the generic DMA API, which do have
        some potential for issues in the older drivers but we'll handle those
        as case by case fixes.
      
        A new myrs driver for the DAC960/mylex raid controllers to replace the
        block based DAC960 which is also being removed by Jens in this merge
        window.
      
        Plus the usual slew of trivial changes"
      
      [ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
        wonder. There's also a "myrb" driver, where the 'b' stands for
        'block'. Truly, somebody has got mad naming skillz. - Linus ]

      Pull libnvdimm updates from Dan Williams:
      
       - Improve the efficiency and performance of reading nvdimm-namespace
         labels. Reduce the amount of label data read at driver load time by a
         few orders of magnitude. Reduce heavyweight call-outs to
         platform-firmware routines.
      
       - Handle media errors located in the 'struct page' array stored on a
         persistent memory namespace. Let the kernel clear these errors rather
         than an awkward userspace workaround.
      
       - Fix Address Range Scrub (ARS) completion tracking. Correct occasions
         where the kernel indicates completion of ARS before submission.
      
       - Fix asynchronous device registration reference counting.
      
       - Add support for reporting an nvdimm dirty-shutdown-count via sysfs.
      
       - Fix various small libnvdimm core and uapi issues.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added 1) superblock checksum feature, 2)
        implemented new mount option which we can disable/enable checkpoint to
        provide atomic updates of entire filesystem, 3) refactored quota
        operations to enhance its consistency along with checkpoint, 4) fixed
        subtle IO hang conditions and roll-forward recovery flow to resurrect
        any fsync'ed inode metadata.
      
        Enhancements:
         - add checksum to keep superblock contents more safe
         - add checkpoint=disable/enable to support A/B update of entire filesystem
         - use plug for readahead IO in readdir
         - add more IO counts to avoid block layer hacks
      
        Bug fixes:
         - prevent data corruption issue for hardware encryption
         - fix IO hang issues when GC is heavily triggered
         - add missing up_read in __write_node_page
