Capability header next field is an offset relative to the start of
the INFO buffer. tmp->next is assigned the proper value but iterations
implemented in vfio_info_cap_add and vfio_info_cap_shift use next
as an offset between the headers. When coping with multiple capabilities
this leads to an Oops.

The semaphore 'sem' in isert_device is used as completion, but in a
counting fashion as isert_connected_handler could be called multiple times
during which it allows for that number of waiters (isert_accept_np) to
continue without blocking, each consuming one node out from the list

The semaphore 'poll_sem' is a simple mutex, so it should be written as one.

Add the mshc_2 node for supporting T-flash.
And it needs to add the "mshc*" aliases. Because dwmmc driver should be

If there is no aliases for mshc, then it might be set to the wrong

This allocates spare interrupts for mach-davinci. These extra interrupts

Some slave devices uses address window instead of single register for read
and/or write of data. With the src/dst_port_window_size the address window
can be specified and the DMAengine driver should use this information to
correctly set up the transfer to loop within the provided window.

Commit: 20d0189b1012 ("block: Introduce new bio_split()")
and
Commit: 4b1faf931650 ("block: Kill bio_pair_split()")
in 3.14 we lost the call to trace_block_split() from bio_split().
Commit: cda22646adaa ("block: add call to split trace point")
in 4.5 added it back for blk_queue
