      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      [NET]: Make core networking code use seq_open_private · cf7732e4
      Pavel Emelyanov authored
      
      
      This concerns the ipv4 and ipv6 code mostly, but also the netlink
      and unix sockets.
      
      The netlink code is an example of how to use the __seq_open_private()
      call - it saves the net namespace on this private.

      [NET]: Make /proc/net per network namespace · 457c4cbc
      Eric W. Biederman authored
      
      
      This patch makes /proc/net per network namespace.  It modifies the global
      variables proc_net and proc_net_stat to be per network namespace.
      The proc_net file helpers are modified to take a network namespace argument,
      and all of their callers are fixed to pass &init_net for that argument.
      This ensures that all of the /proc/net files are only visible and
      usable in the initial network namespace until the code behind them
      has been updated to be handle multiple network namespaces.
      
      Making /proc/net per namespace is necessary as at least some files
      in /proc/net depend upon the set of network devices which is per
      network namespace, and even more files in /proc/net have contents
      that are relevant to a single network namespace.

      [IPV6]: fix flowlabel seqfile handling · 1b7c2dbc
      James Morris authored
      
      
      There's a bug in the seqfile show operation for flowlabel objects, where 
      each hash chain is traversed cumulatively for each element.  The following 
      function is called for each element of each chain:
      
      static void ip6fl_fl_seq_show(struct seq_file *seq, struct ip6_flowlabel *fl)
      {
              while(fl) {
                      seq_printf...
      		
      		fl = fl->next;
      	}
      }
      
      Thus, objects can appear mutliple times when reading 
      /proc/net/ip6_flowlabel, as the above is called for each element in the 
      chain.
      
      The solution is to remove the while() loop from the above, and traverse 
      each chain exactly once, per the patch below.  This also removes the 
      ip6fl_fl_seq_show() function, which does nothing else.
