Use kmemdup_user rather than duplicating its implementation
This is a little bit restricted to reduce false positives
The semantic patch that makes this output is available
in scripts/coccinelle/api/memdup_user.cocci.

This was done to handle a number of conflicts in the batman-adv
and winbond drivers properly. It also now allows us to fix up the sysfs
attributes properly that were not in the .37 release due to them being
only in this tree at the time.

The spectra nand driver takes quite some time to initialize because
it needs to scan the whole nand disk to find the latest block table.
This patch initializes the spectra nand driver asynchronously so that
other things in the kernel can initialize in parallel to the scanning
operation.

Currently there are some driver initialization logic that
is not part of nand_pci_probe function. This will result in
that part of driver initialization code executing even on
platforms without the corresponding hardware which is always
dangerous.

blk_queue_ordered() has been deprecated and replaced with
blk_queue_flush() by Tejun. However, use of blk_queue_ordered()
in spectra nand driver has not been converted yet and thus results
in the following build error.
drivers/staging/spectra/ffsport.c: In function SBD_setup_device:
drivers/staging/spectra/ffsport.c:659: error: implicit declaration of function blk_queue_ordered
drivers/staging/spectra/ffsport.c:659: error: QUEUE_ORDERED_DRAIN_FLUSH undeclared (first use in this function)

Hi,
The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.
This patch removes such casts from drivers/staging/spectra/

The block device drivers have all gained new lock_kernel
calls from a recent pushdown, and some of the drivers
were already using the BKL before.
This turns the BKL into a set of per-driver mutexes.
Still need to check whether this is safe to do.
file=$1
name=$2
if grep -q lock_kernel ${file} ; then
if grep -q 'include.*linux.mutex.h' ${file} ; then
sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
else
sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}
fi
sed -i ${file} \
-e "/^#include.*linux.mutex.h/,$ {

The spectra driver doesn't compile with today linux-next
The problem is that it tries to use a blk_fs_request macro. Searching
for this macro I saw that it used to exist in linux/blkdev.h as
#define blk_fs_request(rq) ((rq)->cmd_type == REQ_TYPE_FS)
This patch solves the issue eliminating the unnecessary (and now inexistent) wrapper
