This patch change current command name from cmd to c_node.
because we are using the member name, 'cmd', for command control ioctl in another structure.
so, this patch changes it to c_node to avoid such confusing.

This patch fixes the issue that when buffer allocation is requested
without iommu, the allocation is failed.
Without iommu, dma_alloc_attrs function allocates some memory region
and returns cpu address so this patch makes the cpu address to be set
to buf->kvaddr correctly.
Changelog v2:
- fix buffer free
. Without iommu, dma_free_attrs function requires kernel space address
as argument. So it changes the argument, buf->pages to buf->kvaddr.

This patch considers no iommu support to kernel space mapping
of console framebuffer.
Without iommu, we get physical address instead of device address
after dma_alloc_attrs function is called. So we should consider
the case without iommu when it maps console framebuffer with
kernel space.
Changelog v2:
- calll vunmap function only with iommu support.

Check that the AGP aperture can be mapped. This follows a similar change
done for Radeon (commit 365048ff, drm/radeon: AGP memory is only I/O if
the aperture can be mapped by the CPU.).
The patch fixes the following error seen on G5 iMac:
nouveau E[ DRM] failed to create kernel channel, -12

The idea here is to move to a finer grained reset.
In some cases we may not need reset every block, and
in other cases we may not need to re-init the entire
asic.

The 720p and 1080p entries are completely redundant, as we are matching

Window properties are programmed through a shared aperture and have to
happen atomically. Also we do the read-update-write dance on some of the

To make sure that different functions don't stumble over each other
protect the register access with a mutex.

This reverts commit 79f77bf9a4e3dd5ead006b8f17e7c4ff07d8374e.
This is obviously wrong, and I have no idea how I missed seeing the
warning in testing: I must just not have looked at the right logs. The
caller bumps rq_resused/rq_next_page, so it will always be hit on a
large enough read.

Eliminate struct map_info from dm-snap.
map_info->ptr was used in dm-snap to indicate if the bio was tracked.
If map_info->ptr was non-NULL, the bio was linked in tracked_chunk_hash.
This patch removes the use of map_info->ptr. We determine if the bio was
tracked based on hlist_unhashed(&c->node). If hlist_unhashed is true,
the bio is not tracked, if it is false, the bio is tracked.

Don't use map_info any more in dm-raid1.
map_info was used for writes to hold the region number. For this purpose
we add a new field dm_bio_details to dm_raid1_bio_record.
map_info was used for reads to hold a pointer to dm_raid1_bio_record (if
the pointer was non-NULL, bio details were saved; if the pointer was
NULL, bio details were not saved). We use
dm_raid1_bio_record.details->bi_bdev for this purpose. If bi_bdev is
NULL, details were not saved, if bi_bdev is non-NULL, details were
saved.
