Fix a rare pte_chain memory leak in do_no_page()

A little fix which is needed if both the "compat ioctl consolidation" and
"move job control fields from task_struct to signal_struct" patches are
applied.

From: Roland McGrath <roland@redhat.com>

This patch completes what was started with the `process_group' accessor
function, moving all the job control-related fields from task_struct into
signal_struct and using process_foo accessor functions to read them.  All
these things are per-process in POSIX, none per-thread.  Off hand it's hard
to come up with the hairy MT scenarios in which the existing code would do
insane things, but trust me, they're there.  At any rate, all the uses
being done via inline accessor functions now has got to be all good.

I did a "make allyesconfig" build and caught the few random drivers and
whatnot that referred to these fields.  I was surprised to find how few
references to ->tty there really were to fix up.  I'm sure there will be a
few more fixups needed in non-x86 code.  The only actual testing of a
running kernel with these patches I've done is on my normal minimal x86
config.  Everything works fine as it did before as far as I can tell.

One issue that may be of concern is the lack of any locking on multiple
threads diddling these fields.  I don't think it really matters, though
there might be some obscure races that could produce inconsistent job
control results.  Nothing shattering, I'm sure; probably only something
like a multi-threaded program calling setsid while its other threads do tty
i/o, which never happens in reality.  This is the same situation we get by
using ->group_leader->foo without other synchronization, which seemed to be
the trend and noone was worried about it.

Fix an ordering problem whcih was causing cpufreq oopses in sysfs.

From: Francois Romieu <romieu@fr.zoreil.com>

- dscc4_release_ring() must not appear in dscc4_{open/close} as the rings
  are allocated/freed in dscc4_{found1/free1};

- more elegant handling of return status in dscc4_found1().

When the BKL was removed from ext3 we lost locking coverage for
get_block()-versus-get_block().  Nobody seems to have hit the race because
get_block() almost always runs under i_sem: only memory pressure-based
writeout over a file hole runs outside i_sem.

ext2 uses the dedicated i_meta_lock spinlock in the inode to provide the
needed locking.  But ext3 already has an rwsem around all the get_block()
activity to protect it from truncate-related races.

So this patch just converts that rwsem into a semaphore, so concurrent
get_block() can never occur.  This will be more efficient than adding the new
spinlock.

We lose the ability to have two threads run get_block() against the same file
at the same time but again, that only happens during pageout over a hole
anyway.

(Kudos Alex Tomas for noticing the bug)

I'd like to kill willy's CONFIG_EISA_ALWAYS kludge.  So make EISA_bus a
variable always when CONFIG_EISA is set and initialize it to 1 for alpha.
We probably want to do that only if the system actually supports eisa, but
I keep the old behaviour for now.

The patch squelches build errors in the kernel-doc make targets by adding
documentation to arguements previously not documented, and updating the
argument names where they have changed.

From: Roland McGrath <roland@redhat.com>

This was supposed to be part of the recent mm_struct.saved_auxv[] patch.

The /proc addition is half the reason for the patch, and the more important
one (letting you debug live processes, while NT_AUXV in core dumps lets you
debug dead ones).  The patch below was supposed to be part of the original.

Shed some much-needed light.

From: Arun Sharma <arun.sharma@intel.com>, kevin.tian@intel.com

Move a whole bunch of filesystem ioctl conversion functions out of per-arch
files and into fs/compat_ioctl.c

It moves linux32_dirent to compat.h and renames it as compat_dirent. 
linux32_dirent has been eliminated from ia64.  Other archs should do the
same.

We'll leave old_linux_dirent32 as is, since it seems to be arch specific
(ia64 doesn't use it for example).

From: Matthew Dobson <colpatch@us.ibm.com>

Here's a small update to the numnodes fix that went into -mm3.  The biggest
changes are:

1) move the actual NODES_SHIFT and MAX_NUMNODES definitions into
   linux/numa.h and include this in linux/mmzone.h, instead of being
   directly in linux/mmzone.h.  This allows other files to include *just*
   the NUMNODES stuff w/out grabbing all of mmzone.h.

2) pull NODE_SHIFT out of linux/mm.h.  This isn't used anywhere in the
   kernel, and it will only get confused with NODES_SHIFT.

3) Fix the IA64 patch.  The original patch I had sent out hadn't been
   tested on IA64.  It was mostly right, but there were circular
   dependencies.  All better now, and acked by Jesse.

4) In linux/mmzone.h, insert code to define MAX_NODES_SHIFT based on the
   size of unsigned long.  For 64-bit arches, we can have a much larger
   value.  This allows IA64 to have 100's or 1000's of nodes.
   MAX_NODES_SHIFT is defined as 10 (ie: 1024 nodes) for 64-bit for now,
   although it could likely be much larger.  For 32-bit it is 6 (ie: 64
   nodes).

5) Small cleanup in include/asm-arm/memory.h.  Mostly the result of the
   new linux/numa.h file.  Much cleaner and more readable now.

From: Matthew Dobson <colpatch@us.ibm.com>

Fix up the ia64 arch.

From: Matthew Dobson <colpatch@us.ibm.com>

Fix up the arm arch.  This needs to be reviewed.  Relatively
straightforward replacement of NR_NODES with standard MAX_NUMNODES.

From: Matthew Dobson <colpatch@us.ibm.com>

Fix up the sh arch.  sh defined NR_NODES, change sh to use standard
MAX_NUMNODES instead.

From: Matthew Dobson <colpatch@us.ibm.com>

Remove MAX_NR_NODES.  This value is only used in a couple of places, and
it's incorrectly used in all those places as far as I can tell.  Replace
with MAX_NUMNODES.  Create MAX_NODES_SHIFT and use this value to check
NODES_SHIFT is appropriate.  A possible future patch should make
MAX_NODES_SHIFT vary based on 32 vs.  64 bit archs.

From: Matthew Dobson <colpatch@us.ibm.com>

This starts a series of cleanups against the way in which the various
architectures specify the number of nodes and memory zones.  We end up
supporting up to 1024 memory zones on ia64, which is a recent requirement.

Has been tested on ia32, ia64 (UMA), ppa64 (UMA) and NUMAQ.


Make sure MAX_NUMNODES is defined in one and only one place.  Remove
superfluous definitions.  Instead of defining MAX_NUMNODES in
asm/numnodes.h, we define NODES_SHIFT there.  Then in linux/mmzone.h we
turn that NODES_SHIFT value into MAX_NUMNODES.

Allow the printk log buffer size to be selected with a __setup parameter,
`log_buf_len=N', where N must be a power-of-two.

The default, initial statically allocated buffer size is still determined via
kernel config.

Most of the changes come from Paul `Rusty' Russell. Now we
modify the skbs only for IPVS packets.
