f507cd2203 ps3/block: Replace mtd/ps3vram by block/ps3vram
Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block
device driver.

The ps3vram driver exposes unused video RAM on the PS3 as a block device
suitable for storage or swap.  Fast data transfer is achieved using a local
cache in system RAM and DMA transfers via the GPU.

The new driver is ca. 50% faster for reading, and ca. 10% for writing.

d58ab5cf09 mtd: physmap: fix NULL pointer dereference in error path
commit e480814f13 ("[MTD] [MAPS] physmap:
fix wrong free and del_mtd_{partition,device}") introduces a NULL pointer
dereference in physmap_flash_remove when called from the error path in
physmap_flash_probe (if map_probe failed).

Call del_mtd_{partition,device} only if info->cmtd was not NULL.

229cc58ba2 mtd_dataflash: fix probing of AT45DB321C chips.
Commit 771999b65f ("[MTD] DataFlash: bugfix,
binary page sizes now handled") broke support for probing AT45DB321C flash
chips.  These chips do not support the "page size" status bit, so if we
match the JEDEC id return early.

e480814f13 [MTD] [MAPS] physmap: fix wrong free and del_mtd_{partition,device}
commit 176bf2e0f1 ("physmap: fix leak of
memory returned by parse_mtd_partitions") deals with a memory leak and
frees the pointer array of mtd_partition after the call to
add_mtd_partitions().  the problem is that mtd_table[x]->name still points
to the freed memory.

Aldo physmap_flash_remove() should call del_mtd_partitions() or
del_mtd_device() only once.

will get -ENODEV instead of an oops.

f429b2ea8e UBI: add ioctl compatibility
UBI ioctl's do not work when running 64-bit kernel and 32-bit
user-land. Fix this by adding the compat_ioctl method.

Also, UBI serializes all ioctls, so more than one ioctl at a time
is not a problem. Amd UBI does not seem to depend on anything else,
so use unlocked_ioctl instead of ioctl (no BKL needed).

cffb4add03 mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTD
Add ps3vram driver, which exposes unused video RAM on the PS3 as a MTD
device suitable for storage or swap.  Fast data transfer is achieved
using a local cache in system RAM and DMA transfers via the GPU.

a808ad3b0d [MTD] [NAND] ndfc driver
The current ndfc driver only compiles under arch/ppc. This arch was
removed from the kernel. I notice the event entry for the ndfc in
Kconfig has been removed in 2.6.28.

This patch converts the ndfc to a proper OF (OpenFirmware) driver. I
can give a working example of the DTS if needed.

The patch has been in production use on the PIKA Warp Appliance and is
in use by others. The Warp basically boots from NAND, so the ndfc driver
is very important to us.
