This makes it possible to ensure that any clients which use
__alloc_skb always allocate memory from the DMA zone.

Previously deprecated smmu calls have been removed. These
changes also caused the reorganization of a key data structure
and logic.

Due to incorrect padding, rule attributes are not present
at 32bit multiples, which is leading to rule geenration
failure. Add changes to the rule padding.

This change primarily fixes timeout issue observed during
command send as part of read and write operations. This will
do proper cleanup of the GENI in command timeout with cancel
and abort operations while waiting for the done event.

There are two times H/W reset during UFS power on. It will impact

This patch adds new IPC log file to dump IRQ registers to know
the interrupt status in dma mode. This will help in debugging
interrupt storm issues in dma mode.

Also increase the IPC log buffer size.

Check for RX data in rx buffer for faulty transfer and add
delay of 2 msecs delay in order for dma rx transfer
to be actually completed.

Also dump required qup registers when the uart dma rx data is
seen as all zeros.

Add ioctl for adding new IPC log buffer in UART driver.
If BT host driver observes a fault in BT transfers this ioctl
needs to be called. On this ioctl call uart driver will change
the logging to new file so that the issue scenario
could be preserved in old UART IPC log files.

Don't allow IOCTL_KGSL_MAP_USER_MEM to import user memory that was
already allocated and mapped by KGSL in the first place.  Remapping
memory never makes sense and it messes up reference counting in the
pools.

Currently driver allocating RX buffer once in port open and use the
same buffer for each RX transfer. This buffer is not cleared in driver.
In some scenarios when SW got DMA_DONE interrupt and the RX buffer we are
still seeing the previously completed RX data in DDR buffer. DMA_DONE from
HW doesn't confirm that the DATA is copied to DDR, sometimes we are queuing
the stale data from previous transfer to tty flip_buffer.

This change is to memset RX buffer to zero after tty_flip_buffer_push
so that memset change will easily help us to identify suck scenarios.

This patch fixes two issues observed during recent test with SN220.
Fix IBI issue to set the payload len based on clients config and
configures the same for master.

Also fix the hot join issue observed during unregistering IBI
which basically creates race between generation of hot join event
and unregistering of IBI. Hence avoid disabling the interrupt and
resetting IBI controller.
