This moves page pinning (get_user_pages_fast()/put_page()) code out of
the platform IOMMU code and puts it to VFIO IOMMU driver where it belongs
to as the platform code does not deal with page pinning.

At the moment only one group per container is supported.
POWER8 CPUs have more flexible design and allows naving 2 TCE tables per
IOMMU group so we can relax this limitation and support multiple groups
per container.
This adds TCE table descriptors to a container and uses iommu_table_group_ops
to
TCE tables might get too big in case of 4K IOMMU pages and DDW enabled
on huge guests (hundreds of GB of RAM) so the kernel might be unable to
allocate contiguous chunk of physical memory to store the TCE table.
To address this, POWER8 CPU (actually, IODA2) supports multi-level TCE tables,
up to
This changes few functions to receive a iommu_table_group pointer

Hello,
The patch 86c22f8c9a3b from Wed Nov 12 19:59:38 2014 in linux-next
introduces a file that contains two exported functions:
pcc_mbox_request_channel and pcc_mbox_free_channel. As far as I can see,
these functions are not used by any modules in the kernel source tree.
Is there some code

Applied to drm-misc, thanks.

Currently this test always returs zero code and a child process returns
non-zero code only if the last testcase failed.

This adds support for Freescale NAND flash controller (NFC) found on
various devices such as Vybrid (VF610), MPC5125, MCF54418 (ColdFire)
and Kinetis K70.
The patchset is based on the patchset by Bill Pringlemeir, see:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/295419
A variant of this
Enable NAND access by adding pinmux and NAND flash controller node
to device tree. The NAND chips currently used on the Colibri VF61
requires 8-bit ECC per 512 byte page, hence specify 32-bit ECC
strength per 2k page size.

This adds the NAND flash controller (NFC) peripherial. The driver
supports the SLC NAND chips found on Freescale's Vybrid Tower System
Module. The Micron NAND chip on the module needs 4-bit ECC per 512
byte page. Use 24-bit ECC per 2k page, which is supported by the
driver.

This driver supports Freescale NFC (NAND flash controller) found on
Vybrid (VF610), MPC5125, MCF54418 and Kinetis K70.
Limitations:
- DMA and pipelining not used
- Pages larger than 2k are not supported
- No hardware ECC
The driver has only been tested on Vybrid (VF610).

This adds hardware ECC support using the BCH encoder in the NFC IP.
The ECC encoder supports up to 32-bit correction by using 60 error
correction bytes. There is no sub-page ECC step, ECC is calculated
always accross the whole page (up to 2k pages).
