netlink overrun was broken while improvement of netlink.
Destination socket is used in the place where it was meant to be source socket,
so that now overrun is never sent to user netlink sockets, when it should be,
and it even can be set on kernel socket, which results in complete deadlock
of rtnetlink.
Suggested fix is to restore status quo passing source socket as additional
argument to netlink_attachskb().
A little explanation: overrun is set on a socket, when it failed
to receive some message and sender of this messages does not or even
have no way to handle this error. This happens in two cases:
1. when kernel sends something. Kernel never retransmits and cannot
wait for buffer space.
2. when user sends a broadcast and the message was not delivered
to some recipients.

Patch from Tony Lindgren
This patch adds the missing cache flushes to common low-level
init that are needed to access the IO region. These flushes
are normally done at the end of devicemaps_init(), but we
need to detect the OMAP core type early.

Patch from Nicolas Pitre
Since:
if (unlikely(__res || __ex_flag))
produces worse code on ARM than:
if (unlikely(__res | __ex_flag))
I therefore made it more explicit:
__res |= __ex_flag;
if (unlikely(__res != 0))
so it is not seen as a typo again.
Also made everything static inline rather than macros for better readability
(both produce the same code after all).
And finally added missing \t from multi-line assembly code.

q->ordcolor must only be flipped on initial queueing of a hardbarrier
request.
Constructing ordered sequence and requeueing used to pass through
__elv_add_request() which flips q->ordcolor when it sees a barrier
request.
This patch separates out elv_insert() from __elv_add_request() and uses
elv_insert() when constructing ordered sequence and requeueing.
elv_insert() inserts the given request at the specified position and
does nothing else.

This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

Compound pages on SMP systems can now often be freed from pagetables via
the release_pages path. This uses put_page_testzero which does not handle
compound pages at all. Releasing constituent pages from process mappings
decrements their count to a large negative number and leaks the reference
at the head page - net result is a memory leak.
The problem was hidden because the debug check in put_page_testzero itself
actually did take compound pages into consideration.
Fix the bug and the debug check.
