Ben Dooks 046c9d321f [ARM] 4788/1: S3C24XX: Fix paramet to s3c2410_dma_ctrl if S3C2410_DMAF_AUTOSTART used.
Fix the channel parameter to s3c2410_dma_ctrl() in s3c2410_dma_enqueue()
if the S3C2410_DMAF_AUTOSTART is set on the channel.

Spotted by Steven Ryu at Samsung.

Ben Dooks a07c438faf [ARM] 4787/1: S3C24XX: s3c2410_dma_request() should return the allocated channel number
The s3c2410_dma_request() function should return the channel allocated
instead of zero for success.

Ben Dooks c58f7a1d36 [ARM] 4781/1: S3C24XX: DMA suspend and resume support
If an DMA channel was active at suspend, then ensure that
it is correctly reconfigured when the system resumes.

Note, the previous policy was for each driver to handle their
own reconfiguration on resume. The policy has been changed to
make the individual driver's job easier.

Ben Dooks c6709e8ef5 [ARM] 4780/1: S3C2412: Allow for seperate DMA channels for TX and RX
The current S3C24XX DMA code does not allow for an peripheral
that has one channel for RX and another for TX.

This patch adds a per-cpu dma operation to select the transmit
or receive channel, and adds support to the S3C2412 for the
seperate DMA channels for TX and RX.

Kay Sievers af5ca3f4ec Driver core: change sysdev classes to use dynamic kobject names
All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

Christoph Lameter 4ba9b9d0ba Slab API: remove useless ctor parameter and reorder parameters
Slab constructors currently have a flags parameter that is never used.  And
the order of the arguments is opposite to other slab functions.  The object
pointer is placed before the kmem_cache pointer.

Convert

        ctor(void *object, struct kmem_cache *s, unsigned long flags)

to

        ctor(struct kmem_cache *s, void *object)

throughout the kernel

Paul Mundt 20c2df83d2 mm: Remove slab destructors from kmem_cache_create().
Slab destructors were no longer supported after Christoph's
c59def9f22 change. They've been
BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

Fix the following sparse errors in arch/arm/plat-s3c24xx/dma.c:

Ben Dooks 48adbcf33b [ARM] 4220/1: S3C24XX: DMA system initialised from sysdev
This patch gets the DMA system for the S3C24XX
ready for the S3C2443, which requires 6 dma channels
at a different stride, and different base IRQ.

The DMA system is now initialised from the same
drivers which apply the DMA mappings, as well
as removing the DMA sysdev intialisation out of
the main init code (which is now being called
from a sysdev probe, so cannot add a new sysdev)

Ben Dooks 0c6022d453 [ARM] 4177/1: S3C24XX: Add DMA channel allocation order
Allow the CPU code, and any board specific initialisation
code to change the allocation order of the DMA channels,
or stop a peripheral allocating any DMA at-all.

This is due to the scarce mapping of DMA channels on
some earlier S3C24XX cpus, where the selection changes
depending on the channel in use.
