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:

screw up generation of FLAT binaries, this warning is not usable for systems

... 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.
text data bss dec hex filename
304 0 0 304 130 memset.old.o
text data bss dec hex filename
228 0 0 228 e4 memset.o
Since this is an import of a file from newlib, I'm not touching
the formatting or correcting any checkpatch errors.
Note also that even if the two files for the CRIS v10 and CRIS v32
are identical at the moment, it might be possible to tweak the
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.

Building vmlinux.o were moved up in the dependency chain so we started
to build it before the kallsym stuff. This was done to let modpost
report section mismatch bugs even when the final link failed.
Originally I had expected the dependency of $(kallsyms.o) to
cover this but it turns out that we need to be even more explicit.
Fix this by adding a conditional dependency on firat target
used in the kallsyms serie of builds.

I just read the excellent LWN writeup of the vmsplice

wasn't stopped by the CONFIG_CC_STACKPROTECTOR option...
because it plain should have been...
Some analysis later.. it turns out that the following line
in the top level Makefile, added by you in October 2007,
entirely disables CONFIG_CC_STACKPROTECTOR ;(
With this line removed the exploit will be nicely stopped.
CFLAGS += $(call cc-option, -fno-stack-protector)
Now I realize that certain distros have patched gcc to
compensate for their lack of distro wide CFLAGS, and it's
great to work around that... but would there be a way to NOT
disable this for CONFIG_CC_STACKPROTECTOR please?
It would have made this exploit not possible for those kernels
that enable this feature (and that includes distros like Fedora)

Move the assignment to KBUILD_CFLAGS up before including
the arch specific Makefile so arch makefiles may override
the setting.

mlx4_core: Move table_find from fmr_alloc to fmr_enable
mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.
