list: remove prefetching from regular list iterators
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).

hlist: remove software prefetching in hlist iterators
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.

m68k: bitops - Never step beyond the end of the bitmap
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.

MIPS: BCM47xx: Register SSB fallback sprom callback
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.

MIPS: BCM47xx: Extend bcm47xx_fill_sprom with prefix.
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.

SSB: Change fallback sprom to callback mechanism.
Some embedded devices like the Netgear WNDR3300 have two SSB based cards
without an own sprom on the pci bus. We have to provide two different
fallback sproms for these and this was not possible with the old solution.
In the bcm47xx architecture the sprom data is stored in the nvram in the
main flash storage. The architecture code will be able to fill the sprom
with the stored data based on the bus where the device was found.
The bcm63xx code should do the same thing as before, just using the new
API.

The Amazon SE is a lightweight SoC and has no PCI as well as a different

The GPIO pins on the SoCs are multi function and there are several bits
we can use to configure the pins. To be as compatible as possible to
GPIOLIB we add a function
int lq_gpio_request(unsigned int pin, unsigned int alt0,

which lets you configure the 2 "alternate function" bits. This way drivers like
PCI can make use of GPIOLIB without a cubersome wrapper.
