Enable the coretemp driver on an Intel Atom.
I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load). Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.

FLEX_ARRAY_INIT(element_size, total_nr_elements) cannot determine if
either parameter is valid, so flex arrays which are statically allocated
with this interface can easily become corrupted or reference beyond its
allocated memory.
This removes FLEX_ARRAY_INIT() as a struct flex_array initializer since no
initializer may perform the required checking. Instead, the array is now
defined with a new interface:
DEFINE_FLEX_ARRAY(name, element_size, total_nr_elements)
This may be prefixed with `static' for file scope.
This interface includes compile-time checking of the parameters to ensure
they are valid. Since the validity of both element_size and
total_nr_elements depend on FLEX_ARRAY_BASE_SIZE and FLEX_ARRAY_PART_SIZE,
the kernel build will fail if either of these predefined values changes
such that the array parameters are no longer valid.
Since BUILD_BUG_ON() requires compile time constants, several of the
static inline functions that were once local to lib/flex_array.c had to be
moved to include/linux/flex_array.h.

Add a new function to the flex_array API:
int flex_array_shrink(struct flex_array *fa)
This function will free all unused second-level pages. Since elements are
now poisoned if they are not allocated with __GFP_ZERO, it's possible to
identify parts that consist solely of unused elements.

Newly initialized flex_array's and/or flex_array_part's are now poisoned
with a new poison value, FLEX_ARRAY_FREE. It's value is similar to
POISON_FREE used in the various slab allocators, but is different to
distinguish between flex array's poisoned kmem and slab allocator poisoned
kmem.
This will allow us to identify flex_array_part's that only contain free
elements (and free them with an addition to the flex_array API). This
could also be extended in the future to identify `get' uses on elements
that have not been `put'.
If __GFP_ZERO is passed for a part's gfp mask, the poisoning is avoided.
These elements are considered to be in-use since they have been
initialized.

This function will zero the element at element_nr in the flex_array.
Although this is equivalent to using flex_array_put() and passing a
pointer to zero'd memory, flex_array_clear() does not require such a
pointer to memory that would most likely need to be allocated on the
caller's stack which could be significantly large depending on
element_size.

Previous behavior was "bottom-up" in each section from the pattern "F:"
entry that matched. Now information is entered into the various lists in
the "as entered" order for each matched section.
This also allows the F: entry to be put anywhere in a section, not just as
the last entries in the section.
And a couple of improvements:
Don't alphabetically sort before outputting the matched scm, status,
subsystem and web sections.
Ignore content after a single email address so these entries are acceptable

then "THE REST".

Julia Lawall suggested that get_maintainers.pl should have the
ability to include signatories of commits that are modified by
a particular patch.
Vegard Nossum did something similar once.

The modified script looks the commits for all lines in the
patch, and includes the "-by:" signatories for those commits.
It uses the same git-min-percent, git-max-maintainers, and
git-min-signatures options. git-since is ignored.
It can be used independently from the --git default, so
./scripts/get_maintainers.pl --nogit --git-blame <patch>
or
./scripts/get_maintainers.pl --nogit --git-blame -f <file>
is acceptable.
If used with -f <file>, all lines/commits for the file are
checked.
--git-blame can be slow if used with -f <file>
--git-blame does not work with -f <directory>

On exit, the need to recompute statistics is recorded, and new statistics

The expected effect is to reduce processor wakeup latency from sleep

Fix the menu idle governor which balances power savings, energy efficiency
and performance impact.
The reason for a reworked governor is that there have been serious
performance issues reported with the existing code on Nehalem server
systems.
To show this I'm sure Andrew wants to see benchmark results:
(benchmark is "fio", "no cstates" is using "idle=poll")
no cstates current linux new algorithm
1 disk 107 Mb/s 85 Mb/s 105 Mb/s
2 disks 215 Mb/s 123 Mb/s 209 Mb/s
12 disks 590 Mb/s 320 Mb/s 585 Mb/s
In various power benchmark measurements, no degredation was found by our
measurement&diagnostics team. Obviously a small percentage more power was
used in the "fio" benchmark, due to the much higher performance.
While it would be a novel idea to describe the new algorithm in this
commit message, I cheaped out and described it in comments in the code
instead.

In our case, we actually get read/write/exec protection down to the page

There is a performance decrease (which depends greatly on the workload)
however as the hardware/software interaction was not optimized at design
