Based largely upon work by John Heffner.

This patch implements both per interface and global new IPv6 MIBs counters 
through netlink based on new IP MIBs draft, 64 bit counters are not supported 
here because of performance issues. It coexists old IPv6 MIBs counters (which 
are through proc file system) for the compatibility.

- After calling scatterwalk_copychunks walk_in might point to the next
  page which will break scatterwalk_samebuf (in this case src_p should
  point to tmp_src anyway and scatterwalk_samembuf returns 0).

- scatterwalk_samebuf should also check for equal offsets inside the page
  (just bad for performance in some cases).

(TBF does not allow attaching filters as it has only one class,
filter should be attached either to TBF's parent or to its child)

When trying to spddelete individual entries using setkey, spddelete always 
fails.  The culprit is in net/af_key.c; spdadd sets the family field of the 
selector when creating an entry, but spddelete doesn't when building a 
selector to match for xfrm_policy_bysel.  Trivial fix is to have spddelete 
set the family field in the selector in same way spdadd does.

helper function to write-back the dirty and accessed bits from
ptep_establish().

Right now this defaults to the same old "set_pte()" that we've
always done, except for x86 where we now fix the (unlikely)
race in updating accessed bits and dropping a concurrent dirty
bit.

preparation for pte update race fix.

This does not actually use the information yet, but
the next few patches will start to put it to some
good use.

Fix over long nodemask clearing in get_mem_policy() by using the
right size for the node mask.

In xfrm_state_find, the larval state never actually matures with
Openswan so it only ever gets deleted by the timer which means
that the time crash can't happen :)  It becomes a (possible) memory
leak instead.

Even with a 16kB stack, we have been seeing stack overflows on PPC64
under stress.  This patch implements separate per-cpu stacks for
processing interrupts and softirqs, along the lines of the
CONFIG_4KSTACKS stuff on x86.  At the moment the stacks are still 16kB
but I hope we can reduce that to 8kB in future.  (Gcc is capable of
adding instructions to the function prolog to check the stack pointer
whenever it moves it downwards, and I want to use that when I try
using 8kB stacks so I can be confident that we aren't overflowing the
stack.)

This patch, from Venkatesh Pallipadi, changes x86 IO-APICs to use fixed
interrupt delivery instead of lowest priority to support larger number
of CPUs.  Only bigsmp is affected by this cleanup.

We can avoid the local_irq_enable() in sched_yield() because schedule()

Currently the ACPI binding script in the Laptop Mode doc always says "20
seconds" and "2 hours" for the timeouts it uses.  This is incorrect if the
user changed the config values, so we print something more general.

PMD_SIZE is not a compile-time constant on sparc.  Use min() in there so
that the cluster size will be evaluated at runtime if the architecture
insists on doing that.

It's initialising slot 24 in two places.  Gerd Knorr <kraxel@bytesex.org> says

The 32bit generic nops added with a previous patch to x86-64 alternative()
