This patch is not present in Joerg's tree and the add_device API in
the PAMU driver requires this patch.
Will this patch be part of v3.9-rc1?

Hi Srivatsa,
I think there is some elegance in Lai's proposal of using a local
trylock for the reader uncontended case and global rwlock to deal with
the contended case without deadlocks. He apparently didn't realize
initially that nested read locks are common, and he seems to have
confused you

Added the following domain attributes for the FSL PAMU driver:
1. Added new iommu stash attribute, which allows setting of the
LIODN specific stash id parameter through IOMMU API.
2. Added an attribute for enabling/disabling DMA

Hi Kumar,Ben,
I am implementing the Freescale PAMU (IOMMU) driver using the Linux IOMMU API.
In this particular patch, I have added a new field to dev_archdata structure to
store the dma domain information.
This field is updated whenever we attach a device to an iommu domain.
Regards
Varun

Hi Christophe,
This patch modifies the behaviour of the MPC8xx/8xxx watchdog. On the MPC8xx,
at 133Mhz, the maximum timeout of the watchdog timer is 1s, which means it
must
be pinged twice a second. This is not in line with the Linux watchdog concept
which is based on a default watchdog
Currently we use the link register to branch up high in the early MMU on
syscall entry path. Unfortunately, this trashes the link stack as the
address we are going to is not associated with the earlier mflr.
This patch simply converts us to used the count register (volatile over
syscalls anyway)

USE PTRS_PER_PTE to indicate the size of pte page. To support THP,
later patches will be changing PTRS_PER_PTE value.
