Fix bug #2230.

I've corresponded with the submitter and he did find a real bug -- when we
were merging I/O requests we didn't always take the oldest request start
time, which would cause a couple of the calculations like wait time and
average queue size to be too small.  He found it mathematically but having
done so, I think logic and inspection makes it easy to verify.

On a really small memory machine (or one with a monstrous kernel memory leak)
we can end up calling blk_congestion_wait() before the waitqueue_heads are set
up.

This piece of the THREAD_SIZE cleanup got dropped.  If you make THREAD_SIZE
> 8k, the init thread overlaps the .init section and gets smashed.  I've
gone ahead and killed INIT_THREAD_SIZE throughout as it wasn't doing much.
This also saves 4k when we use 4k stacks.  Please apply.  Couple more minor
pieces remaining.

keventd and friends are currently holding /dev/console open three times.
It's all inherited from init.

Steal the relevant parts of daemonize() to fix that up.

print_objinfo() dumps the first few characters of an interesting object for
debugging.  It used the wrong object len (including debug padding, instead
of just the data area), which could cause an oops if DEBUG_PAGEALLOC is
enabled.

- remove unused `file *' arg from do_write_mem()

- Add checking for copy_from_user() failures in do_write_mem()

- Return correct value from kmem writes() when a fault is encountered.  A
  write()-style syscall's return values are:

   0 when nothing was written and there was no error (someone tried to
   write zero bytes)

   >0: the number of bytes copied, whether or not there was an error.
   Userspace detects errors by noting that the write() return value is less
   than was requested.

   <0: there was an error and no bytes were copied

reiserfs can safely use the generic fs aio functions.

reiserfs_file_write() can use stale metadata after a schedule.

Two reiserfs_file_write bugs, where items can change during a schedule.

From: Chris Mason <mason@suse.com>

Make sure reiserfs uses a reasonable number when restarting long unbounded
transactions (creating holes or deleting files).

Without this patch, the number of blocks requested grows with each
transaction restart, until it hits MAX_BATCH_COUNT and starts forcing
commits with every new transaction.

fsstress manages to setup a sequence of events that allow an attempt to
perform direct-io on a tail.  bh_result->b_page == NULL, which causes the
PageLocked and PageWriteback checks to perform a NULL deref, causing the
oops.

This is needed to get any of the SGML documentation to build with 2.6.4.

From: James Simmons <jsimmons@infradead.org>

This patch merges two of the drawing functions.  The patch uses aligned
transfers when possible even on displays where the characters are not byte
align.  Tested on my my laptop for 12 bit width fonts and 8 bit wide fonts.
It works very nicely.

There's no point in calling mark_page_accessed() here.  The page is never on
the LRU so all mark_page_accessed() will do is to set PG_referenced, which we
immediately clear again.

Add a debug check for workqueues nested more than three deep via the
direct-run-workqueue() path.

Because keventd is a resource which is shared between unrelated parts of the
kernel it is possible for one person's workqueue handler to accidentally call
another person's flush_scheduled_work().  thockin managed it by calling
mntput() from a workqueue handler.  It deadlocks.

It's simple enough to fix: teach flush_scheduled_work() to go direct when it
discovers that the calling thread is the one which should be running the
work.

Note that this can cause recursion.  The depth of that recursion is equal to
the number of currently-queued works which themselves want to call
flush_scheduled_work().  If this ever exceeds three I'll eat my hat.

This patch fixes a bug in the SELinux compute_av code; the current code
yields the right access computation but can cause unnecessary (but
harmless) processing to occur when transition permission wasn't granted in
the first place by the TE configuration.  Thanks to Chad Hanson of TCS for
reporting the bug.

modpost or to be more specific sumversion.c was not behaving correct when
used with O= and MODULE_VERSION was used.  Previously it failed to use
local .h when calculation the md-sum in case of a O= build.

The following patch introduces the following:

- A generic get_next_line()

- Check that the topmost part of the directory matches

- Using strrch when checking for file with suffix .o

- Use NOFAIL for allocations in sumversion

- Avoid memory leak in new_module

The generic get_next_line will pay off when Andreas implmentation of
storing symbol addresses in a seperate file is introduced.
