V4L/DVB (7102): make tuner-core.c:tuner_list static

tuner_list can become static - and it's anyway a way too generic name
for a global variable - see commit b00ef4b8d8c29bfb5f6f92ee60bc04b604f36ef2

static...

V4L/DVB (7091): radio-si470x improvements and seldom problem fixed in tuning functions

I updated the radio-si470x driver another time. Here are the commented history entries:

- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.

- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.

- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.

- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

V4L/DVB (7133): Fix Kconfig dependencies

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.

This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.

After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.

This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

dentries: Extract common code to remove dentry from lru

Extract the common code to remove a dentry from the lru into a new function
dentry_lru_remove().

Two call sites used list_del() instead of list_del_init().  AFAIK the
performance of both is the same.  dentry_lru_remove() does a list_del_init().

As a result dentry->d_lru is now always empty when a dentry is freed.

Embed a struct path into struct nameidata instead of nd->{dentry,mnt}

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.

Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
  <dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
  struct path in every place where the stack can be traversed
- it reduces the overall code size:

without patch series:
   text    data     bss     dec     hex filename
5321639  858418  715768 6895825  6938d1 vmlinux

with patch series:
   text    data     bss     dec     hex filename
5320026  858418  715768 6894212  693284 vmlinux

This patch:

Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

cris: import memset.c from newlib: fixes compile error with newer (pre4.3) gcc

Adrian Bunk reported the following compile error with a SVN head GCC:

...
CC arch/cris/arch-v10/lib/memset.o

/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:192: error: lvalue required as increment operand
... etc ...

This is due to the use of the construct:

*((long*)dst)++ = lc;

Which is no longer legal since casts don't return an lvalue.

The solution is to import the implementation from newlib,
which is continually autotested together with GCC mainline,
and uses the construct:

*(long *) dst = lc; dst += 4;

With this change, the generated code actually shrinks 76 bytes
since gcc notices that it can use autoincrement for the move
instruction in CRIS.

Note also that even if the two files for the CRIS v10 and CRIS v32

CRIS v32 version. Thus, I'm not yet folding them into the same file,
at least not until we've done some research on it.

RDMA/cma: Do not issue MRA if user rejects connection request

There's an undesirable interaction with issuing MRA requests to
increase connection timeouts and the listen backlog.

When the rdma_cm receives a connection request, it queues an MRA with
the ib_cm.  (The ib_cm will send an MRA if it receives a duplicate
REQ.)  The rdma_cm will then create a new rdma_cm_id and give that to
the user, which in this case is the rdma_user_cm.

If the listen backlog maintained in the rdma_user_cm is full, it
destroys the rdma_cm_id, which in turns destroys the ib_cm_id.  The
ib_cm_id generates a REJ because the state of the ib_cm_id has changed
to MRA sent, versus REQ received.  When the backlog is full, we just
want to drop the REQ so that it is retried later.

Fix this by deferring queuing the MRA until after the user of the
rdma_cm has examined the connection request.

slub: Support 4k kmallocs again to compensate for page allocator slowness

Currently we hand off PAGE_SIZEd kmallocs to the page allocator in the
mistaken belief that the page allocator can handle these allocations
effectively. However, measurements indicate a minimum slowdown by the
factor of 8 (and that is only SMP, NUMA is much worse) vs the slub fastpath
which causes regressions in tbench.

Increase the number of kmalloc caches by one so that we again handle 4k
kmallocs directly from slub. 4k page buffering for the page allocator
will be performed by slub like done by slab.

At some point the page allocator fastpath should be fixed. A lot of the kernel
would benefit from a faster ability to allocate a single page. If that is
done then the 4k allocs may again be forwarded to the page allocator and this
patch could be reverted.

slub: Fallback to kmalloc_large for failing higher order allocs

Slub already has two ways of allocating an object. One is via its own
logic and the other is via the call to kmalloc_large to hand off object
allocation to the page allocator. kmalloc_large is typically used
for objects >= PAGE_SIZE.

We can use that handoff to avoid failing if a higher order kmalloc slab
allocation cannot be satisfied by the page allocator. If we reach the
out of memory path then simply try a kmalloc_large(). kfree() can
already handle the case of an object that was allocated via the page
allocator and so this will work just fine (apart from object
accounting...).

For any kmalloc slab that already requires higher order allocs (which
makes it impossible to use the page allocator fastpath!)
we just use PAGE_ALLOC_COSTLY_ORDER to get the largest number of
objects in one go from the page allocator slowpath.

On a 4k platform this patch will lead to the following use of higher
order pages for the following kmalloc slabs:

8 ... 1024 order 0
2048 .. 4096 order 3 (4k slab only after the next patch)

We may waste some space if fallback occurs on a 2k slab but we
are always able to fallback to an order 0 alloc.

Determine the bits to be set at the time the slab is created. Store
in a new allocflags field and add the flags in allocate_slab().
