67a52bb90b [ARM] fix build-breaking 7a192ec commit
The commit:

    platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'

contains this:

-static int __exit pxa2xx_flash_remove(struct device *dev)
+static int __exit pxa2xx_flash_remove(struct platform_device *dev)
...
-       .remove         = __exit_p(pxa2xx_flash_remove),
+       .remove         = __devexit_p(pxa2xx_flash_remove),

which leads to the following build error:

`pxa2xx_flash_remove' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o

This is not the only instance of it in this patch - all __exit_p's
touched by this patch have been converted to __devexit_p's without
regard to the original function.

Let's revert this change and, if we are going to convert functions
to be __devexit/__devinit, lets have that as a _separate_ patch doing
just that change.

a3ec947c85 vfs: simple_set_mnt() should return void
simple_set_mnt() is defined as returning 'int' but always returns 0.
Callers assume simple_set_mnt() never fails and don't properly cleanup if
it were to _ever_ fail.  For instance, get_sb_single() and get_sb_nodev()
should:

        up_write(sb->s_unmount);
        deactivate_super(sb);

if simple_set_mnt() fails.

Since simple_set_mnt() never fails, would be cleaner if it did not
return anything.

7a192ec334 platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
This patch fixes the bug reported in
	http://bugzilla.kernel.org/show_bug.cgi?id=11681.

"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

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.

physmap_flash_probe (if map_probe failed).

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

Commit 771999b65f ("[MTD] DataFlash: bugfix,

chips.  These chips do not support the "page size" status bit, so if we

47a72688fa mtd: flash mapping support for Dreamcast VMU.
This patch adds support for the Sega Dreamcast visual memory unit as a
flash mapping. It requires changes in the maple bus driver (posted
separately) to support block reads and writes.

The VMU is a 'smart' flash device, with a built-in 8-bit controller -
for instance there is an erase before a write but it is hidden from the
user. But the device's overall behaviour means it works well with the
mtd layer and it is appropriate to add it as an mtd mapping.

7ebc8d56f4 [ARM] pxa: move DMA registers definitions into <mach/dma.h>
1. Driver code where pxa_request_dma() is called will most likely
   reference DMA registers as well,  and it is really unnecessary
   to include pxa-regs.h just for this. Move the definitions into
   <mach/dma.h> and make relevant drivers include it instead of
   <mach/pxa-regs.h>.

2. Introduce DMAC_REGS_VIRT as the virtual address base for these
   DMA registers. This allows later processors to re-use the same
   IP while registers may start at different I/O address.

This also cleans up a few spurious references to X86_PC in the
driver space - those certainly should be X86.

e0c7ae376a x86: rename X86_GENERICARCH to X86_32_NON_STANDARD
X86_GENERICARCH is a misnomer - it contains non-PC 32-bit architectures
that are not included in the default build.

Rename it to X86_32_NON_STANDARD.

36b477d005 UBI: fix resource de-allocation
GregKH asked to fix UBI which has fake device release method. Indeed,
we have to free UBI device description object from the release method,
because otherwise we'll oops is someone opens a UBI device sysfs file,
then the device is removed, and he reads the file. With this fix, he
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).

ade44ce07c UBI: allow all ioctls
Some ioctl's in UBI are enabled only when debugging is switched
on. There is not particular reason for this, just noone needed
them. However, some people need the now for their user-space
development. Thus, allow these ioctl's even if UBI debugging
is disabled.
