mtd: always initialize 'stats' in struct mtd_oob_ops
As the 'stats' field in struct mtd_oob_ops is used in conditional expressions, ensure it is always zero-initialized in all such structures to prevent random stack garbage from being interpreted as a pointer.
Strictly speaking, this problem currently only needs to be fixed for struct mtd_oob_ops structures subsequently passed to mtd_read_oob(). However, this commit goes a step further and makes all instances of struct mtd_oob_ops in the tree zero-initialized, in hope of preventing future problems, e.g. if struct mtd_req_stats gets extended with write statistics at some point.

treewide: kmalloc() -> kmalloc_array()
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of:
kmalloc(a * b, gfp)
with: kmalloc_array(a * b, gfp)
as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.
The tools/ directory was manually excluded, since it has its own implementation of kmalloc().
The Coccinelle script used for this was:
// Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@

We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

schedule_delayed_work() happening when the work is already pending is a cheap no-op. Don't bother with ->wbuf_queued logics - it's both broken (cancelling ->wbuf_dwork leaves it set, as spotted by Jeff Harris) and pointless. It's cheaper to let schedule_delayed_work() handle that case.

JFFS2: don't fail on bitflips in OOB
JFFS2 was designed without thought for OOB bitflips, it seems, but they can occur and will be reported to JFFS2 via mtd_read_oob()[1]. We don't want to fail on these transactions, since the data was corrected.
[1] Few drivers report bitflips for OOB-only transactions. With such drivers, this patch should have no effect.

jffs2: get rid of jffs2_sync_super
Currently JFFS2 file-system maps the VFS "superblock" abstraction to the write-buffer. Namely, it uses VFS services to synchronize the write-buffer periodically.
The whole "superblock write-out" VFS infrastructure is served by the 'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and writes out all dirty superblock using the '->write_super()' call-back. But the problem with this thread is that it wastes power by waking up the system every 5 seconds no matter what. So we want to kill it completely and thus, we need to make file-systems to stop using the '->write_super' VFS service, and then remove it together with the kernel thread.
This patch switches the JFFS2 write-buffer management from '->write_super()'/'->s_dirt' to a delayed work. Instead of setting the 's_dirt' flag we just schedule a delayed work for synchronizing the write-buffer.
