This is removes the use of software prefetching from the regular list
iterators. We don't want it. If you do want to prefetch in some
iterator of yours, go right ahead. Just don't expect the iterator to do
it, since normally the downsides are bigger than the upsides.
It also replaces <linux/prefetch.h> with <linux/const.h>, because the
use of LIST_POISON ends up needing it. <linux/poison.h> is sadly not
self-contained, and including prefetch.h just happened to hide that.
Suggested by David Miller (networking has a lot of regular lists that
are often empty or a single entry, and prefetching is not going to do
anything but add useless instructions).

They not only increase the code footprint, they actually make things
slower rather than faster. On internationally acclaimed benchmarks
("make -j16" on an already fully built kernel source tree) the hlist
prefetching slows down the build by up to 1%.
(Almost all of it comes from hlist_for_each_entry_rcu() as used by
avc_has_perm_noaudit(), which is very hot due to all the pathname
lookups to see if there is anything to do).
The cause seems to be two-fold:
- on at least some Intel cores, prefetch(NULL) ends up with some
microarchitectural stall due to the TLB miss that it incurs. The
hlist case triggers this very commonly, since the NULL pointer is the
last entry in the list.
- the prefetch appears to cause more D$ activity, probably because it
prefetches hash list entries that are never actually used (because we
ended the search early due to a hit).
Regardless, the numbers clearly say that the implicit prefetching is
simply a bad idea. If some _particular_ user of the hlist iterators
wants to prefetch the next list entry, they can do so themselves
explicitly, rather than depend on all list iterators doing so
implicitly.

Kmemleak frees objects via RCU and when CONFIG_DEBUG_OBJECTS_RCU_HEAD
is enabled, the RCU callback triggers a call to free_object() in
lib/debugobjects.c. Since kmemleak is initialised before debug objects
initialisation, it may result in a kernel panic during booting. This
patch moves the kmemleak_init() call after debug_objects_mem_init().

The kmemleak_seq_next() function tries to get an object (and increment
its use count) before returning it. If it could not get the last object
during list traversal (because it may have been freed), the function
should return NULL rather than a pointer to such object that it did not
get.

find_next bitops on m68k (find_next_zero_bit, find_next_bit, and
find_next_bit_le) may cause out of bounds memory access
when the bitmap size in bits % 32 != 0 and offset (the bitnumber
to start searching at) is very close to the bitmap size.
For example,
unsigned long bitmap[2] = { 0, 0 };
find_next_bit(bitmap, 63, 62);
1. find_next_bit() tries to find any set bits in bitmap[1],
but no bits set.
2. Then find_first_bit(bimap + 2, -1)
3. Unfortunately find_first_bit() takes unsigned int as the size argument.
4. find_first_bit will access bitmap[2~] until it find any set bits.
Add missing tests for stepping beyond the end of the bitmap to all
find_{first,next}_*() functions, and make sure they never return a value
larger than the bitmap size.

Some devices like the Netgear WGT634u are using minuses between the blocks
of the MAC address and other devices are using colons to separate them.

Some members of the struct ssb_sprom where not filled with data available
in the NVRAM. Some attribute names in the NVRAM changed from SPROM version
3 to version 4. This patch was done by analyzing the the pci sprom parser
in the ssb code and some open source parts of the braodcom wireless driver
used on embedded devices.

We are generating the prefix based on the PCI bus address the device is
on. This is done like Broadcom does it in their code expect that the the
bus number is increased by one. In the SB bus implementation used by
Broadcom the SB bus emulates a PCI bus so the kernel sees one PCI bus
more then in our implementation. We do not handle prefixes like sb/1/
yet as they are only used on the new bus which is not implemented yet.

When an other SSB based device without an own SPROM is attached, using the
PCI bus to the main SSB based device, the data normally found in the SPROM
will be stored in the NVRAM on modern devices. The keys, to load the data
from the NVRAM, are all using some sort of prefix like pci/1/1/, pci/1/3/
or sb/1/ before the actual key. This patch extends bcm47xx_fill_sprom() to
make it possible to read out these values when some prefix was used.
The keys for the SPROM data used on the main chip does not have a prefix.
