net: rmnet_ctrl_usb: Block file close until tx URBs are transmitted

Cherry picked from 16599ec35c3bc8965eb26d33cac044518df88c73

Rmnet control driver is directly killing tx URBs submitted to HSIC
HW if userspace closes the file. When a file is close, all pending
data needs to get flushed. Hence wait for the pending tx URBs to
finish transfer with a timeout before file close. This will complete
all the pending transfers gracefully on tx path so that mdm device
does not miss any control channel information upon file close.

usb: gadget: u_ether: Fix memory corruption in TX path

When data aggregation is enabled, multiple skb buffers are copied
into a single USB request buffer.  When ever a USB request queue
is failed, make sure that req->length is reset to 0.  Otherwise
when the same request is used again, the stale length field is used
to access the request buffer.  This would lead to memory corruption.

The xmit function keeps the partial request at the beginning of the
queue.  Always put the idle request at the back of the queue.

ARM: Allow arm_memblock_steal() to remove memory from any RAM region

Allow arm_memblock_steal() to remove memory from any RAM region,
including highmem areas.  This allows memory to be stolen from the
very top of declared memory, including highmem areas, rather than
our precious lowmem.

block: blk-merge: don't merge the pages with non-contiguous descriptors

blk_rq_map_sg() function merges the physically contiguous pages to use same
scatter-gather node without checking if their page descriptors are
contiguous or not.

Now when dma_map_sg() is called on the scatter gather list, it would
take the base page pointer from each node (one by one) and iterates
through all of the pages in same sg node by keep incrementing the base
page pointer with the assumption that physically contiguous pages will
have their page descriptor address contiguous which may not be true
if SPARSEMEM config is enabled. So here we may end referring to invalid
page descriptor.

Following table shows the example of physically contiguous pages but
their page descriptor addresses non-contiguous.
-------------------------------------------
| Page Descriptor    |   Physical Address |
------------------------------------------
| 0xc1e43fdc         |   0xdffff000       |
| 0xc2052000         |   0xe0000000       |
-------------------------------------------

With this patch, relevant blk-merge functions will also check if the
physically contiguous pages are having page descriptors address contiguous
or not? If not then, these pages are separated to be in different
scatter-gather nodes.

usb: gadget: u_data_hsic: Cancel pending MDM write work during remove

The HSIC bridge driver removes the data bridge platform device
during subsystem restart.  If gadget driver does not cancel pending
MDM write work, we end up accessing interface structure after it
is unbounded.
