The netfilter code had very good documentation: the Netfilter Hacking HOWTO.
Noone ever read it.
So this time I'm trying something different, using a bit of Knuthiness.

A dummy inline function of register_nosave_region_late was accidentally
removed by the recent PM patch that introduced suspend notifiers.
This elimination causes the following compiler error on PPC machines.

This patch fixes the problem.

Have put_unaligned() warn if types would be wrong
for assignment, slap force-casts where needed. Cast the
result of get_unaligned to typeof(*ptr). With that in
place we get proper typechecking, both from gcc and from sparse,
including that for bitwise types.

We really need force-cast when converting to final result type;
unsigned long can be silently converted to integer types and
to pointers, but not to bitwise.

u32* volatile cyclone_timer means volatile auto pointer to u32,
which is clearly not what had been intended (we never even take
the address of that variable, let alone pass it to something that
could change it behind our back). u32 volatile * is what the
authors apparently wanted to say, but in reality we don't need that
qualifier there at all - it's (properly) only passed to iomem helpers
which takes care of that stuff just fine.

Convert rel_info to host-endian before calling ip6_tnl_err().
The things become much more straightforward that way.
The key observation (and the reason why that code actually
worked) is that after ip6_tnl_err() we either immediately
bailed out or had rel_info set to 0 or had it set to host-endian
and guaranteed to hit
(rel_type == ICMP_DEST_UNREACH && rel_code == ICMP_FRAG_NEEDED)
case. So inconsistent endianness didn't really lead to bugs,
but it had been subtle and prone to breakage. New variant is
saner and obviously safe.

Add an above_background_load() function which can be used by other
subsystems to detect if there is anything besides niced tasks running.
Place it in sched.h to allow it to be compiled out if not used.
Unused for now, but it is a useful hint to the IO scheduler and to
swap-prefetch.

While learning about schedstats I found that the documentation in the tree
is old. I updated it and found some interesting stuff like schedstats
version 14 is the same as version and version 13 never saw a kernel
release! Also there are 6 fields in the current schedstats that are not
used anymore. Nick had made them irrelevant in commit
476d139c21 but never removed them.
Thanks to Rick's perl script who I borrowed some of the updated descriptions
from.

it is enough to disable interrupts to get the precise rq-clock
of the local CPU.
this also solves an NMI watchdog regression: the NMI watchdog
calls touch_softlockup_watchdog(), which might deadlock on
rq->lock if the NMI hits an rq-locked critical section.
