      mtd: s3c2410: drop useless / misspelled debug prints · a05973a7
      Brian Norris authored
      s3c2410_nand_probe is not the name of the function.
      
      These prints have little utility, so let's just kill them.

      pxa3xx_flash_ids wasn't initialized to 0, which in certain cases could
      end up containing corrupted values in its members. Fix this to avoid
      possible issues.

      mtd: pxa3xx_nand: fix driver when num_cs is 0 · e423c90a
      Robert Jarzmik authored
      As the devicetree binding doesn't require num_cs to exist or be strictly
      positive, and neither does the platform data case, a bug appear when
      num_cs is set to 0 and panics the kernel.
      
      The issue is that in alloc_nand_resource(), chip is dereferenced without
      having a value assigned when num_cs == 0.
      
      Fix this by returning ENODEV is num_cs == 0.
      
      The panic seen is :
      Unable to handle kernel NULL pointer dereference at virtual address 000002b8

      mtd: pxa3xx-nand: handle PIO in threaded interrupt · 24542257
      Robert Jarzmik authored
      Change the handling of the data stage in the driver : don't pump data in
      the top-half interrupt, but rather schedule a thread for non dma cases.
      
      This will enable latencies in the data pumping, especially if delays are
      required. Moreover platform shall be more reactive as other interrupts
      can be served while pumping data.
      
      No throughput degradation was observed, at least on the zylonite
      platform, while a slight degradation was being expected.

      mtd: nand: pxa3xx: Fix PIO FIFO draining · 8dad0386
      Maxime Ripard authored
      The NDDB register holds the data that are needed by the read and write
      commands.
      
      However, during a read PIO access, the datasheet specifies that after each 32
      bytes read in that register, when BCH is enabled, we have to make sure that the
      RDDREQ bit is set in the NDSR register.
      
      This fixes an issue that was seen on the Armada 385, and presumably other mvebu
      SoCs, when a read on a newly erased page would end up in the driver reporting a
      timeout from the NAND.

      Linux 4.0-rc1 · c517d838
      Linus Torvalds authored
      .. after extensive statistical analysis of my G+ polling, I've come to
      the inescapable conclusion that internet polls are bad.
      
      Big surprise.
      
      But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
      margin, in a poll that people weren't even supposed to participate in.
      Who can argue with solid numbers like that? 5,796 votes from people who
      can't even follow the most basic directions?
      
      In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
      but with a total of 29,110 votes right now.
      
      Now, arguably, that vote spread is only about 3,200 votes, which is less
      than the almost six thousand votes that the "please ignore" poll got, so
      it could be considered noise.
      
      But hey, I asked, so I'll honor the votes.

      debugfs: leave freeing a symlink body until inode eviction · 0db59e59
      Al Viro authored
      As it is, we have debugfs_remove() racing with symlink traversals.
      Supply ->evict_inode() and do freeing there - inode will remain
      pinned until we are done with the symlink body.
      
      And rip the idiocy with checking if dentry is positive right after
      we'd verified debugfs_positive(), which is a stronger check...

      trylock_super(): replacement for grab_super_passive() · eb6ef3df
      Konstantin Khlebnikov authored
      I've noticed significant locking contention in memory reclaimer around
      sb_lock inside grab_super_passive(). Grab_super_passive() is called from
      two places: in icache/dcache shrinkers (function super_cache_scan) and
      from writeback (function __writeback_inodes_wb). Both are required for
      progress in memory allocator.
      
      Grab_super_passive() acquires sb_lock to increment sb->s_count and check
      sb->s_instances. It seems sb->s_umount locked for read is enough here:
      super-block deactivation always runs under sb->s_umount locked for write.
      Protecting super-block itself isn't a problem: in super_cache_scan() sb
      is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
      are still active. Inside writeback super-block comes from inode from bdi
      writeback list under wb->list_lock.
      
      This patch removes locking sb_lock and checks s_instances under s_umount:
      generic_shutdown_super() unlinks it under sb->s_umount locked for write.
      New variant is called trylock_super() and since it only locks semaphore,
      callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
      they're done.

      VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry) · e36cb0b8
      David Howells authored
      Convert the following where appropriate:
      
       (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry).
      
       (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).
      
       (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry).  This is actually more
           complicated than it appears as some calls should be converted to
           d_can_lookup() instead.  The difference is whether the directory in
           question is a real dir with a ->lookup op or whether it's a fake dir with
           a ->d_automount op.
      
      In some circumstances, we can subsume checks for dentry->d_inode not being
      NULL into this, provided we the code isn't in a filesystem that expects
      d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
      use d_inode() rather than d_backing_inode() to get the inode pointer).
      
      Note that the dentry type field may be set to something other than
      DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
      manages the fall-through from a negative dentry to a lower layer.  In such a
      case, the dentry type of the negative union dentry is set to the same as the
      type of the lower dentry.
      
      However, if you know d_inode is not NULL at the call site, then you can use
      the d_is_xxx() functions even in a filesystem.
      
      There is one further complication: a 0,0 chardev dentry may be labelled
      DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE.  Strictly, this was
      intended for special directory entry types that don't have attached inodes.

      Use d_is_dir() rather than d_inode and S_ISDIR().  Note that this will include
      fake directories such as automount triggers.

      Apparmor: Use d_is_positive/negative() rather than testing dentry->d_inode · 729b8a3d
      David Howells authored
      Use d_is_positive(dentry) or d_is_negative(dentry) rather than testing
      dentry->d_inode as the dentry may cover another layer that has an inode when
      the top layer doesn't or may hold a 0,0 chardev that's actually a whiteout.

      David Howells authored
      mediated_filesystem() should use dentry->d_sb not dentry->d_inode->i_sb and
      should avoid file_inode() also since it is really dealing with the path.

      VFS: Split DCACHE_FILE_TYPE into regular and special types · 44bdb5e5
      David Howells authored
      Split DCACHE_FILE_TYPE into DCACHE_REGULAR_TYPE (dentries representing regular
      files) and DCACHE_SPECIAL_TYPE (representing blockdev, chardev, FIFO and
      socket files).
      
      d_is_reg() and d_is_special() are added to detect these subtypes and
      d_is_file() is left as the union of the two.
      
      This allows a number of places that use S_ISREG(dentry->d_inode->i_mode) to
      use d_is_reg(dentry) instead.

      VFS: Add a fallthrough flag for marking virtual dentries · df1a085a
      David Howells authored
      Add a DCACHE_FALLTHRU flag to indicate that, in a layered filesystem, this is
      a virtual dentry that covers another one in a lower layer that should be used
      instead.  This may be recorded on medium if directory integration is stored
      there.
      
      The flag can be set with d_set_fallthru() and tested with d_is_fallthru().

      VFS: Introduce inode-getting helpers for layered/unioned fs environments · 155e35d4
      David Howells authored
      Introduce some function for getting the inode (and also the dentry) in an
      environment where layered/unioned filesystems are in operation.
      
      The problem is that we have places where we need *both* the union dentry and
      the lower source or workspace inode or dentry available, but we can only have
      a handle on one of them.  Therefore we need to derive the handle to the other
      from that.
      
      The idea is to introduce an extra field in struct dentry that allows the union
      dentry to refer to and pin the lower dentry.

      Pull MIPS updates from Ralf Baechle:
       "This is the main pull request for MIPS:
      
         - a number of fixes that didn't make the 3.19 release.
      
         - a number of cleanups.
      
         - preliminary support for Cavium's Octeon 3 SOCs which feature up to
           48 MIPS64 R3 cores with FPU and hardware virtualization.
      
         - support for MIPS R6 processors.
      
           Revision 6 of the MIPS architecture is a major revision of the MIPS
           architecture which does away with many of original sins of the
           architecture such as branch delay slots.  This and other changes in
           R6 require major changes throughout the entire MIPS core
           architecture code and make up for the lion share of this pull
           request.
      
         - finally some preparatory work for eXtendend Physical Address
           support, which allows support of up to 40 bit of physical address
           space on 32 bit processors"
      
           [ Ahh, MIPS can't leave the PAE brain damage alone.  It's like
             every CPU architect has to make that mistake, but pee in the snow
             by changing the TLA.  But whether it's called PAE, LPAE or XPA,
