      Merge branch 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux · 69048e01
      Linus Torvalds 提交于
      Pull parisc updates from Helge Deller:
       "The three major changes in this patchset is a implementation for
        flexible userspace memory maps, cache-flushing fixes (again), and a
        long-discussed ABI change to make EWOULDBLOCK the same value as
        EAGAIN.
      
        parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
        to keep HP-UX compatibility.  Since we will probably never implement
        full HP-UX support, we prefer to drop this compatibility to make it
        easier for us with Linux userspace programs which mostly never checked
        for both values.  We don't expect major fall-outs because of this
        change, and if we face some, we will simply rebuild the necessary
        applications in the debian archives"

      hpfs: optimize quad buffer loading · 1c0b8a7a
      Mikulas Patocka 提交于
      HPFS needs to load 4 consecutive 512-byte sectors when accessing the
      directory nodes or bitmaps.  We can't switch to 2048-byte block size
      because files are allocated in the units of 512-byte sectors.
      
      Previously, the driver would allocate a 2048-byte area using kmalloc,
      copy the data from four buffers to this area and eventually copy them
      back if they were modified.
      
      In the current implementation of the buffer cache, buffers are allocated
      in the pagecache.  That means that 4 consecutive 512-byte buffers are
      stored in consecutive areas in the kernel address space.  So, we don't
      need to allocate extra memory and copy the content of the buffers there.
      
      This patch optimizes the code to avoid copying the buffers.  It checks
      if the four buffers are stored in contiguous memory - if they are not,
      it falls back to allocating a 2048-byte area and copying data there.

      hpfs: remember free space · 2cbe5c76
      Mikulas Patocka 提交于
      Previously, hpfs scanned all bitmaps each time the user asked for free
      space using statfs.  This patch changes it so that hpfs scans the
      bitmaps only once, remembes the free space and on next invocation of
      statfs it returns the value instantly.
      
      New versions of wine are hammering on the statfs syscall very heavily,
      making some games unplayable when they're stored on hpfs, with load
      times in minutes.
      
      This should be backported to the stable kernels because it fixes
      user-visible problem (excessive level load times in wine).

      parisc: add flexible mmap memory layout support · 9dabf60d
      Helge Deller 提交于
      Add support for the flexible mmap memory layout (as described in
      http://lwn.net/Articles/91829). This is especially very interesting on
      parisc since we currently only support 32bit userspace (even with a
      64bit Linux kernel).

      parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc · f5a408d5
      Guy Martin 提交于
      On Linux, only parisc uses a different value for EWOULDBLOCK which
      causes a lot of troubles for applications not checking for both values.
      Since the hpux compat is long dead, make EWOULDBLOCK behave the same as
      all other architectures.

      parisc: convert uapi/asm/stat.h to use native types only · 9391bc77
      Helge Deller 提交于
      The stat.h header file is exported to userspace. Some userspace
      applications failed to compile due to missing/unknown types, so we
      better convert it to use native types only (like it's done on other
      architectures too).

      parisc: fix cache-flushing · 57737c49
      Helge Deller 提交于
      This commit:
      f8dae006: parisc: Ensure full cache coherency for kmap/kunmap
      caused negative caching side-effects, e.g. hanging processes with expect and
      too many inequivalent alias messages from flush_dcache_page() on Debian 5 systems.
      
      This patch now partly reverts it and has been in production use on our debian buildd
      makeservers since a week without any major problems.
