As you've noticed, it is default behavior for iommu fault.
Then why not add it to the IOMMU core ? it's quite generic and can be
useful for others, too.
Thanks,

This is the second try of submitting patches about IOMMU/System MMU
driver for Exynos4 SoCs with the fixes of the following problems
pointed by Russell King.:
- Missing unlocking a spinlock in exynos_iommu_attach_dev().
- atomic_t - int in sysmmu_drvdata.activations
- sysmmu_platdata -
This patch contains a lot of changes of System MMU device definition.
1. Removed sysmmu_ips enumeration that are definitions of ID of System MMU
Instead, a System MMU device descriptor must be bound with a device
descriptor that needs System MMU in machine initialization.
2. Removed MDMA
This patch adds the support for predefined multiple block read/write.

This patchset adds clkdev based clock lookup support and device tree based

With clkdev based clock lookup added to samsung serial driver, the use

With clkdev based clock lookup support, the clock set and get operation
using clock names communicated between the samsung uart driver and the
SoC specific extension can be removed.
In addition to that, for each platform specific extension, add the
default clock selection, number of clock options
The driver probe() function is removed from the SoC specific extensions
and a probe() is added to the common driver.

Hi Linus,
This is Samsung fixes for v3.1
Please pull from:
git://github.com/kgene/linux-samsung.git samsung-fixes-3
These things are needed for v3.1 and if any problems, please let me know.
Arnd, since v3.1 is now close at hand, I'm sending this to Linus...
Thanks.
Best regards,
