      mm: prevent balance_dirty_pages() from doing too much work · d7831a0b
      Richard Kennedy authored
      balance_dirty_pages can overreact and move all of the dirty pages to
      writeback unnecessarily.
      
      balance_dirty_pages makes its decision to throttle based on the number of
      dirty plus writeback pages that are over the calculated limit,so it will
      continue to move pages even when there are plenty of pages in writeback
      and less than the threshold still dirty.
      
      This allows it to overshoot its limits and move all the dirty pages to
      writeback while waiting for the drives to catch up and empty the writeback
      list.
      
      A simple fio test easily demonstrates this problem.
      
      fio --name=f1 --directory=/disk1 --size=2G -rw=write --name=f2 --directory=/disk2 --size=1G --rw=write --startdelay=10
      
      This is the simplest fix I could find, but I'm not entirely sure that it
      alone will be enough for all cases.  But it certainly is an improvement on
      my desktop machine writing to 2 disks.
      
      Do we need something more for machines with large arrays where
      bdi_threshold * number_of_drives is greater than the dirty_ratio ?

      The file opened in acct_on and freshly stored in the ns->bacct struct can
      be closed in acct_file_reopen by a concurrent call after we release
      acct_lock and before we call mntput(file->f_path.mnt).

      spi: bitbang bugfix in message setup · 529ba0d9
      David Brownell authored
      Bugfix to spi_bitbang infrastructure: make sure to always set transfer
      parameters on the first pass through the message's per-transfer loop.
      This can matter with drivers that replace the per-word or per-buffer
      transfer primitives, on busses with multiple SPI devices.
      
      Previously, this could have started messages using the settings left after
      previous messages.  The problem was observed when a high speed chip
      (m25p80 type flash) was running very slowly because a low speed device
      (avr8 microcontroller) had previously used the bus.  Similar faults could
      have driven the low speed device too fast, or used an unexpected word
      size.

      fbdev: add mutex for fb_mmap locking · 537a1bf0
      Krzysztof Helt authored
      Add a mutex to avoid a circular locking problem between the mm layer
      semaphore and fbdev ioctl mutex through the fb_mmap() call.
      
      Also, add mutex to all places where smem_start and smem_len fields change
      so the mutex inside the fb_mmap() is actually used.  Changing of these
      fields before calling the framebuffer_register() are not mutexed.
      
      This is 2.6.31 material.  It removes one lockdep (fb_mmap() and
      register_framebuffer()) but there is still another one (fb_release() and
      register_framebuffer()).  It also cleans up handling of the smem_start and
      smem_len fields used by mutexed section of the fb_mmap().

      spi: add spi_master flag word · 70d6027f
      David Brownell authored
      Add a new spi_master.flags word listing constraints relevant to that
      controller.  Define the first constraint bit: a half duplex restriction.
      Include that constraint in the OMAP1 MicroWire controller driver.
      
      Have the mmc_spi host be the first customer of this flag.  Its coding
      relies heavily on full duplex transfers, so it must fail when the
      underlying controller driver won't perform them.
      
      (The spi_write_then_read routine could use it too: use the
      temporarily-withdrawn full-duplex speedup unless this flag is set, in
      which case the existing code applies.  Similarly, any spi_master
      implementing only SPI_3WIRE should set the flag.)

      spi: new spi->mode bits · b55f627f
      David Brownell authored
      Add two new spi_device.mode bits to accomodate more protocol options, and
      pass them through to usermode drivers:
      
       * SPI_NO_CS ... a second 3-wire variant, where the chipselect
         line is removed instead of a data line; transfers are still
         full duplex.
      
         This obviously has STRONG protocol implications since the
         chipselect transitions can't be used to synchronize state
         transitions with the SPI master.
      
       * SPI_READY ... defines open drain signal that's pulled low
         to pause the clock.  This defines a 5-wire variant (normal
         4-wire SPI plus READY) and two 4-wire variants (READY plus
         each of the 3-wire flavors).
      
         Such hardware flow control can be a big win.  There are ADC
         converters and flash chips that expose READY signals, but not
         many host controllers support it today.
      
      The spi_bitbang code should be changed to use SPI_NO_CS instead of its
      current nonportable hack.  That's a mode most hardware can easily support
      (unlike SPI_READY).

      ext2: return -EIO not -ESTALE on directory traversal through deleted inode · 4d6c13f8
      Bryan Donlan authored
      ext2_iget() returns -ESTALE if invoked on a deleted inode, in order to
      report errors to NFS properly.  However, in ext[234]_lookup(), this
      -ESTALE can be propagated to userspace if the filesystem is corrupted such
      that a directory entry references a deleted inode.  This leads to a
      misleading error message - "Stale NFS file handle" - and confusion on the
      part of the admin.
      
      The bug can be easily reproduced by creating a new filesystem, making a
      link to an unused inode using debugfs, then mounting and attempting to ls
      -l said link.
      
      This patch thus changes ext2_lookup to return -EIO if it receives -ESTALE
      from ext2_iget(), as ext2 does for other filesystem metadata corruption;
      and also invokes the appropriate ext*_error functions when this case is
      detected.

      elf: limit max map count to safe value · 341c87bf
      KAMEZAWA Hiroyuki authored
      With ELF, at generating coredump, some more headers other than used
      vmas are added.
      
      When max_map_count == 65536, a core generated by following kinds of
      code can be unreadable because the number of ELF's program header is
      written in 16bit in Ehdr (please see elf.h) and the number overflows.
      
      ==
      	... = mmap(); (munmap, mprotect, etc...)
      	if (failed)
      		abort();
      ==
      
      This can happen in mmap/munmap/mprotect/etc...which calls split_vma().
      
      I think 65536 is not safe as _default_ and reduce it to 65530 is good
      for avoiding unexpected corrupted core.
      
      Anyway, max_map_count can be enlarged by sysctl if a user is brave..

      alpha: fix percpu build breakage · b01e8dc3
      Tejun Heo authored
      alpha percpu access requires custom SHIFT_PERCPU_PTR() definition for
      modules to work around addressing range limitation.  This is done via
      generating inline assembly using C preprocessing which forces the
      assembler to generate external reference.  This happens behind the
      compiler's back and makes the compiler think that static percpu variables
      in modules are unused.
      
      This used to be worked around by using __unused attribute for percpu
      variables which prevent the compiler from omitting the variable; however,
      recent declare/definition attribute unification change broke this as
      __used can't be used for declaration.  Also, in the process,
      PER_CPU_ATTRIBUTES definition in alpha percpu.h got broken.
      
      This patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions
      and make alpha use it to add __used for percpu variables in modules.  This
      also fixes the PER_CPU_ATTRIBUTES double definition bug.

      fbdev: work around old compiler bug · 15e32524
      Stephen Rothwell authored
      When building with a 4.1.x compiler on powerpc64 (at least) we get this

      drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict
      
      This was introduced by commit ae52bb23
      ("fbdev: move logo externs to header file").  This is a partial revert of
      that commit sufficient to not hit the compiler bug.
      
      Also convert _clut arrays from __initconst to __initdata.
      
      Sam said:
      
        Al analysed this some time ago.  When we say something is const then
        _sometimes_ gcc annotate the section as const(?) - sometimes not.  So if
        we have two variables/functions annotated __*const and gcc decides to
        annotate the section const only in one case we get a section type
        conflict.

      gcov: fix __ctors_start alignment · 2a2325e6
      Heiko Carstens authored
      The ctors section for each object file is eight byte aligned (on 64 bit).
      However the __ctors_start symbol starts at an arbitrary address dependent
      on the size of the previous sections.
      
      Therefore the linker may add some zeroes after __ctors_start to make sure
      the ctors contents are properly aligned.  However the extra zeroes at the
      beginning aren't expected by the code.  When walking the functions
      pointers contained in there and extra zeroes are added this may result in
      random jumps.  So make sure that the __ctors_start symbol is always
      aligned as well.
      
      Fixes this crash on an allyesconfig on s390:

      eventfd: revised interface and cleanups · 13389010
      Davide Libenzi authored
      Change the eventfd interface to de-couple the eventfd memory context, from
      the file pointer instance.
      
      Without such change, there is no clean way to racely free handle the
      POLLHUP event sent when the last instance of the file* goes away.  Also,
      now the internal eventfd APIs are using the eventfd context instead of the
      file*.
      
      This patch is required by KVM's IRQfd code, which is still under
      development.
