This patch is part of a patch-set which changes the MTD interface
from 'mtd->func()' form to 'mtd_func()' form. We need this because
we want to add common code to to all drivers in the mtd core level,
which is impossible with the current interface when MTD clients
call driver functions like 'read()' or 'write()' directly.
At this point we just introduce a new inline wrapper function, but
later some of them are expected to gain more code. E.g., the input
parameters check should be moved to the wrappers rather than be
duplicated at many drivers.
This particular patch introduced the 'mtd_erase()' interface. The
following patches add all the other interfaces one by one.

Fix up trivial conflicts:

Merged into board-usb-a926x.c
- drivers/mtd/maps/lantiq-flash.c
add_mtd_partitions -> mtd_device_register vs changed to use
mtd_device_parse_register.
These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW
affected operations on in-band page data as well. To clarify these
options and to emphasize that their effect is applied per-operation, we
change the primary prefix to MTD_OPS_.

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.

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.

name=$2

if grep -q 'include.*linux.mutex.h' ${file} ; then

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)
