When mapping buffers through the PRIME DMA-buf mmap path we might be
given an offset which has to be respected. The DRM GEM mmap path already
takes care of zeroing out the fake mmap offset, so we can just make the
IOMMU mmap implementation always respect the offset.

When freeing the buffer we don't have any means of determining if the
buffer was read or written, so we must assume both and pass true for
both arguments of drm_gem_put_pages(). Let's fix the code which
currently passes false.

drm_mm_insert_node_generic and drm_mm_remove_node may access same

[49451.856350] BUG: KASAN: wild-memory-access on add
From: Tomasz Figa
The API is not suitable for subsystems consisting of multiple devices
and requires severe hacks to use it. To mitigate this, this patch
implements allocation and address space management locally by using
helpers provided by DRM framework, like other DRM drivers do, e.g.
Tegra.
From: Shunqian Zheng
Rockchip DRM used the arm special API, arm_iommu_*(), to attach
iommu for ARM32 SoCs. This patch convert to common iommu API
so it would support ARM64 like RK3399.
Since previous patch added support for direct IOMMU address space
management, there is no need to use DMA API a
The return value of iommu_map_sg is size_t, it's unsigned,
So check ret < 0 is wrong.
And if iommu_map_sg is error, it's return value is zero, but
rockchip_gem_iommu_map feel the zero return value is success,
bug happen:
[5.227458] [drm:rockchip_gem_iommu_map] *ERROR* failed to map buffer: 0
Some iommu patches on the series[0] "iommu/rockchip: Fix bugs and
enable on ARM64" already landed, So drm/rockchip related patches [1] and [2]
ready to landed, this series just rebase them to lastest drm-next.
And fix some bugs for drm/rockchip drm_mm

The Broadcom SBA RAID is a stream-based device which provides

The return value of dmaengine_prep_slave_sg is not checked, but
eventually it can fail and in that case return 'NULL' causing a
segmentation fault.
Check dmaengine_prep_slave_sg return value and exit in case of
failure. For doing this all the 'void' functions involved has
been turned to 'int'.

Even though it's quite unlikely to happen in this particular
case, clk_get_rate can return '0' if sdd->src_clk is not set
properly. In that case we would have a clear division by '0'.

returns '0'.
