      Pull x86/efi changes from Peter Anvin:
       "The bulk of these changes are cleaning up the efivars handling and
        breaking it up into a tree of files.  There are a number of fixes as
        well.
      
        The entire changeset is pretty big, but most of it is code movement.
      
        Several of these commits are quite new; the history got very messed up
        due to a mismerge with the urgent changes for rc8 which completely
        broke IA64, and so Ingo requested that we rebase it to straighten it
        out."

      linkage.h: fix build breakage due to symbol prefix handling · 126de6b2
      James Hogan authored
      Al's commit e1b5bb6d
      
       ("consolidate cond_syscall and SYSCALL_ALIAS
      declarations") broke the build on blackfin and metag due to the
      following code:
      
        #ifndef SYMBOL_NAME
        #ifdef CONFIG_SYMBOL_PREFIX
        #define SYMBOL_NAME(x) CONFIG_SYMBOL_PREFIX ## x
        #else
        #define SYMBOL_NAME(x) x
        #endif
        #endif
        #define __SYMBOL_NAME(x) __stringify(SYMBOL_NAME(x))
      
      __stringify literally stringifies CONFIG_SYMBOL_PREFIX ##x, so you get
      lines like this in kernel/sys_ni.s:
      
        .weak CONFIG_SYMBOL_PREFIXsys_quotactl
        .set CONFIG_SYMBOL_PREFIXsys_quotactl,CONFIG_SYMBOL_PREFIXsys_ni_syscall
      
      The patches in Rusty's modules-next tree such as "CONFIG_SYMBOL_PREFIX:
      cleanup." cleans up the whole mess around symbol prefixes, so this patch
      just attempts to fix the build in the meantime.
      
      The intermediate definition of SYMBOL_NAME above isn't used and is
      incorrect when CONFIG_SYMBOL_PREFIX is defined as CONFIG_SYMBOL_PREFIX
      is a quoted string literal, so define __SYMBOL_NAME directly depending
      on CONFIG_SYMBOL_PREFIX.

      Make the PROC_I() and PDE() macros internal to procfs.  This means making
      PDE_DATA() out of line.  This could be made more optimal by storing

      proc: Supply a function to remove a proc entry by PDE · a8ca16ea
      David Howells authored
      
      
      Supply a function (proc_remove()) to remove a proc entry (and any subtree
      rooted there) by proc_dir_entry pointer rather than by name and (optionally)
      root dir entry pointer.  This allows us to eliminate all remaining pde->name
      accesses outside of procfs.

      David Howells authored
      
      
      Clean up the pseries scanlog driver's use of procfs:
      
       (1) Don't need to save the proc_dir_entry pointer as we have the filename to
           remove with.
      
       (2) Save the scan log buffer pointer in a static variable (there is only one
           of it) and don't save it in the PDE (which doesn't have a destructor).

      ppc: Clean up rtas_flash driver somewhat · e8eeded3
      David Howells authored
      
      
      Clean up some of the problems with the rtas_flash driver:
      
       (1) It shouldn't fiddle with the internals of the procfs filesystem (altering
           pde->count).
      
       (2) If pid namespaces are in effect, then you can get multiple inodes
           connected to a single pde, thereby rendering the pde->count > 2 test
           useless.
      
       (3) The pde->count fudging doesn't work for forked, dup'd or cloned file
           descriptors, so add static mutexes and use them to wrap access to the
           driver through read, write and release methods.
      
       (4) The driver can only handle one device, so allocate most of the data
           previously attached to the pde->data as static variables instead (though
           allocate the validation data buffer with kmalloc).
      
       (5) We don't need to save the pde pointers as long as we have the filenames
           available for removal.
      
       (6) Don't try to multiplex what the update file read method does based on the
           filename.  Instead provide separate file ops and split the function.
      
      Whilst we're at it, tabulate the procfile information and loop through it when
      creating or destroying them rather than manually coding each one.

      drm: proc: Use remove_proc_subtree() · 8bc742e1

      Use remove_proc_subtree() rather than remove_proc_entry() to remove a
      minor-specific drm proc directory and all its children.
      
      Things could theoretically be improved by storing the drm_minor pointer in the
      minor-specific dir proc_dir_entry struct data and then scrapping the list of
      proc files - but that's shared with the debugfs interface where you can't do
      that, so I don't see an easy way of doing it.

      drm: proc: Use minor->index to label things, not PDE->name · b63e6aa5
      David Howells authored
      
      
      Use minor->index to label things, not the name field from the proc_dir_entry
      of the /proc/dwm/<minor>/ directory.
      
      Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which
      to render the integer, not a 16-byte buffer.  The longest string an unsigned
      int can give you is 10 chars (4294967295) plus a NUL, so round up to 12 as the
      stack is likely to be 4- or 8-byte aligned.

      reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show() · e42270a1
      David Howells authored
      
      
      Don't access the proc_dir_entry in ReiserFS's r_open(), r_start() r_show()
      procfs interface functions.
      
      ReiserFS stores the ->show() method pointer in PDE->data and the super_block
      pointer in PDE->parent->data.  This isn't changing.
      
      Currently, ReiserFS passes the PDE pointer into seq_file::private from
      r_open() so that r_start() and r_show() can then access it.  Instead, use
      seq_open_private() to allocate a two-pointer struct that's passed through
      seq_file::private and put the ->show() method and the sb pointers in there.

      proc: Supply an accessor for getting the data from a PDE's parent · 4a520d27
      David Howells authored
      
      
      Supply an accessor function for getting the private data from the parent
      proc_dir_entry struct of the proc_dir_entry struct associated with an inode.
      
      ReiserFS, for instance, stores the super_block pointer in the proc directory
      it makes for that super_block, and a pointer to the respective seq_file show
      function in each of the proc files in that directory.
      
      This allows a reduction in the number of file_operations structs, open
      functions and seq_operations structs required.  The problem otherwise is that
      each show function requires two pieces of data but only has storage for one
      per PDE (and this has no release function).

      af_unix: fix a fatal race with bit fields · 60bc851a
      Eric Dumazet authored
      Using bit fields is dangerous on ppc64/sparc64, as the compiler [1]
      uses 64bit instructions to manipulate them.
      If the 64bit word includes any atomic_t or spinlock_t, we can lose
      critical concurrent changes.
      
      This is happening in af_unix, where unix_sk(sk)->gc_candidate/
      gc_maybe_cycle/lock share the same 64bit word.
      
      This leads to fatal deadlock, as one/several cpus spin forever
      on a spinlock that will never be available again.
      
      A safer way would be to use a long to store flags.
      This way we are sure compiler/arch wont do bad things.
      
      As we own unix_gc_lock spinlock when clearing or setting bits,
      we can use the non atomic __set_bit()/__clear_bit().
      
      recursion_level can share the same 64bit location with the spinlock,
      as it is set only with this spinlock held.

      When the bnx2x driver reads the port configuration - mask irrelevant bits.
      
      Without this change, the unintended bits may cause the driver to needlessly
      toggle the link, as a comparison in the link flap avoidance flow will show
      that the old link did not advertise the same capabilities and thus cannot
      be retained.

      This resulted from my commit ca99ca14
      
       which introduced a mutex_trylock
      operation in a path that could execute in interrupt context.  When mutex
      debugging is enabled, the above warns the user when we are in fact
      exectuting in interrupt context
      interrupt context.
      
      After some discussion, It seems that a semaphore is the proper mechanism to use
      here.  While mutexes are defined to be unusable in interrupt context, no such
      condition exists for semaphores (save for the fact that the non blocking api
      calls, like up and down_trylock must be used when in irq context).
