The revision numbers didn't get updated in ages, so they don't really
make sense anymore.

Updating copyright lines, deleting the CVS $Id lines, move
PPP CCP reset related declarations into drivers/isdn/i4l/isdn_ppp_ccp.c.

Dropping every 7th packet was just meant for internal debugging...

Whoever did the tqueue -> workqueue changes didn't really care to look
at how it was used in the HiSax driver, making the driver compile but
oops with NULL pointer derefs.

Oh, and workqueues are really not the right solution here, tasklets are.
But that's for later.

The reset routines are not called concurrently with other call paths,
and holding a spinlock over schedule_timeout() is plain wrong anyway.

Unfortunately, there's still quite a lot of cli() etc left, which however
are not so easy to kill since they protect IRQ handlers against filling
the tx queue, but don't even live in the same file.

I missed sparc64 when I broke up read_barrier_depends in -mm and sent
to Linus.  Please apply this to your tree until Linus is back and I can
fix it.

Patch from Dipankar Sarma <dipankar@in.ibm.com>

There is a check in RCU for idle CPUs which signifies quiescent state
(and hence no reference to RCU protected data) which was broken when
interrupt counters were changed to use thread_info->preempt_count.

Martin's 32 CPU machine with many idle CPUs was not completing any RCU
grace period because RCU was forever waiting for idle CPUs to context
switch.  Had the idle check worked, this would not have happened.  With
no RCU happening, the dentries were getting "freed" (dentry stats
showing that) but not getting returned to slab.  This would not show up
in systems that are generally busy as context switches then would
happen in all CPUs and the per-CPU quiescent state counter would get
incremented during context switch.

This patch fixes a filesystem corrupting bug, present in 2.5.41 through
2.5.44.  It can cause ext2 indirect blocks to not be written out.  A
fsck will fix it up.

Under heavy memory pressure a PF_MEMALLOC task attemtps to write out a
blockdev page whose buffers are already under writeback and which were
dirtied while under writeback.

The writepage call returns -EAGAIN but because the caller is
PF_MEMALLOC, the page was not being marked dirty again.

The page sits on mapping->clean_pages for ever and it not written out.

The fix is to mark that page dirty again for all callers, regardless of
PF_MEMALLOC state.

parisc builds parisc / parisc64 from arch/parisc, but wants different
strings for uname -m, which it can now provide by overwriting
UTS_MACHINE in arch/parisc/Makefile.

DVB is very different in its need to analogue video. This merges the
cleaned up version of the DVB framework from Convergence, which has been
around for a couple of years.

This is the device mapper with Joe's updates applied and in -ac for a bit

This last actually worked in 2.2, but Marc has a laptop with one and
wanted it working again...
