Ben Dooks 06cfa55694 [ARM] 4524/1: S3C: Move register out of include/asm-arm/arch-s3c2410
Move register and other definitions out of the
include/asm-arm/arch-s3c2410 into the the arch
directories of include/asm-arm/plat-s3c24xx and
include/asm-arm/plat-s3c.

This move is in preperation of the merging of
s3c2400 and s3c6400.

this patch can be applied:

This patch moves items of the s3c24xx support into
a new plat-s3c directory for items that use the
s3c24xx support but are not directly s3c24xx
compatible, such as the s3c2400 and s3c6400.

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)

Christoph Lameter e18b890bb0 [PATCH] slab: remove kmem_cache_t
Replace all uses of kmem_cache_t with struct kmem_cache.

The patch was generated using the following script:

	#!/bin/sh
	#
	# Replace one string by another in all the kernel sources.
	#

	set -e

	for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
		quilt add $file
		sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
		mv /tmp/$$ $file
		quilt refresh
	done

The script was run like this

	sh replace kmem_cache_t "struct kmem_cache"

Ben Dooks f105a7dfc5 [ARM] 3764/1: S3C24XX: change type naming to kernel style
Patch from Ben Dooks

The type naming in the s3c24xx dma code is riddled with
typedefs creating _t types, from the code import from 2.4
which is contrary to the current Kernel coding style.

This patch cleans this up, removing the typedefs and
and fixing up the resultant code changes.

Ben Dooks f57e1abd1b [ARM] 3753/1: S3C24XX: DMA fixes
Patch from Ben Dooks

A number of small issues with the S3C24XX DMA have
cropped up, which this patch fixes. These are:

  - check wether we can load another buff in start
  - update state handling in s3c2410_dma_lastxfer
  - only reload in irq if channel is not idle
  - more informative timeout errors (add source)
  - do not call request_irq() with irqs locked
  - added waitforstop function

The patch also adds a S3C2410_DMAOP_STARTED for
the occasions when the driver wants to ensure that
the DMA system load state is resynced after loading.

Albrecht Dre 105bb2698b [PATCH] ARM: 2694/1: [s3c2410/dma] release irq properly to fix kernel oops
Patch from Albrecht Dre

Problem:
When a module requests a DMA channel via the function s3c2410_dma_request(), this function requests the appropriate irq under the name of the client module. When the client module is unloaded, it calls s3c2410_dma_free() which does not free the irq. Consequently, when e.g. running "cat /proc/interrupts", the irq owner points to freed memory, leading to a kernel oops.
File:
linux/arch/arm/mach-s3c2410/dma.c
Fix:
trivial, below

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
