This fix checks the validity of memory device session's
process descriptor before issuing a signal to it while
subsystem restart is performed. This fix avoids accessing
of cleaned-up process descriptor's fields.

On certain PMICs, there is no short circuit (SC) detection available
in LAB module. Add support to detect it manually and disable LAB/IBB
module upon SC detection. In addition, notify it to OLEDB driver to
disable OLEDB module.

Allow clients to specify the IOVA range for fastmap clients
via the DOMAIN_ATTR_GEOMETRY domain attribute.
Presently fastmap only allocates page tables for the IOVA
range specified during the create mapping call. However
clients may want to use IOVA addresses outside this range,
such as for their calls to iommu_map.
So allow clients to extend the available IOVA space by setting
the DOMAIN_ATTR_GEOMETRY domain attribute's
iommu_domain_geometry.aperture_start to
the new start address of the IOVA space and by setting
iommu_domain_geometry.aperture_end to the new end address of the
IOVA space.
The new IOVA space created by iommu_domain_geometry.aperture_start
and iommu_domain_geometry.aperture_end will be a superset of the
IOVA range which was created through the create mapping call.
The DOMAIN_ATTR_GEOMETRY domain attribute can only be set before
attaching.
Calls to set the DOMAIN_ATTR_GEOMETRY domain attribute can only
be used to extend the IOVA space, it cannot shrink the range.
Note that extending the IOVA range will not change the range of
IOVA addresses which will be available to the DMA APIs.

This reverts 'commit 9730348075 ("arm64: Increase the max
granular size") and also sets ARM_DMA_MINALIGN to 128.
ARCH_DMA_MINALIGN is dependent on L1_CACHE_SHIFT but it should
be set to maximum *known* cache line size on ARMv8 systems to
avoid DMA coherecy issues. So setting ARM_DMA_MINALIGN to 128.

req_frm->stream_handle is passed as an argument to
the function msm_isp_get_stream_common_data,
stream_idx can overflow common_data->streams[] and
the code ends up copying an out of bound

The commit '6b4f77 (mm: vmscan: invoke slab shrinkers from shrink_zone())'
fixed the invocation of shrinkers but resulted in lowmemorykiller shrinker
being called more. Reduce the number of lowmemorykiller shrinker
invocations by separating out the lowmemorykiller shrinker from
shrink_slab. This will make lowmemorykiller invoked only once for all zones
reclaimed in the direct reclaim path, and once for each zone in the kswap
path. As a consequence the eligible pages passed to shrink_slab_lmk is now
the reclaimable pages of all zones. Reducing the number of lowmemorykiller
invocations reduces the unnecessary time spent in lowmemorykiller and thus
contention or failures on lowmemorykiller's scan_mutex.
