USB: gadget: qdss: Flush pending works before function unbind

Workqueue might have pending connect/disconnect works when
composite driver calls qdss unbind as part of composition
switch or remove. As qdss_unbind frees up device references
e.g. ep->driver_data, flush pending works from unbind to avoid
any access to them later from work_fn.

ARM: fix executability of CMA mappings

The CMA region was being marked executable:

0xdc04e000-0xdc050000           8K     RW x      MEM/CACHED/WBRA
0xdc060000-0xdc100000         640K     RW x      MEM/CACHED/WBRA
0xdc4f5000-0xdc500000          44K     RW x      MEM/CACHED/WBRA
0xdcce9000-0xe0000000       52316K     RW x      MEM/CACHED/WBRA

This is mainly due to the badly worded MT_MEMORY_DMA_READY symbol, but
there are also a few other places in dma-mapping which should be
corrected to use the right constant.  Fix all these places:

0xdc04e000-0xdc050000           8K     RW NX     MEM/CACHED/WBRA
0xdc060000-0xdc100000         640K     RW NX     MEM/CACHED/WBRA
0xdc280000-0xdc300000         512K     RW NX     MEM/CACHED/WBRA
0xdc6fc000-0xe0000000       58384K     RW NX     MEM/CACHED/WBRA

ARM: dma-mapping: don't allow DMA mappings to be marked executable

DMA mapping permissions were being derived from pgprot_kernel directly
without using PAGE_KERNEL.  This causes them to be marked with executable
permission, which is not what we want.  Fix this.

soc: qcom: smd: Validate read and write addresses

The address from which data has to be read and the address to which the
SMD data has to be written is calculated based on the head and tail
indices for that SMD FIFO. If the indices are corrupted, then the
calculated pointer may be outside of the FIFO and may even be outside of
the range of SMEM.

Validate the read and write addresses to be with in the limits of
receive and send FIFO limits respectively.
