Convert deviceiobook.tmpl to RST and incorporate it into the driver API
manual.
Like the rest of our documentation, this one could use some work. There's
no mention of ioremap() and friends, no mention of io_read*() and friends.
But we have nice documentation for all those folks writing new drivers that
do port I/O :).
The :c:func: notation has been left off of all the read*/write* functions.
There's no kerneldoc comments for them anyway, so those links will never be
live, and writing a bunch of repetitive "read a byte from I/O memory"
comments lacks appeal.

This is a DT-only driver, so the only way to call rcar_pcie_probe() is to
match an entry in rcar_pcie_of_match[], so of_id cannot be NULL.
Furthermore, of_id->data can only be NULL if an rcar_pcie_of_match[] entry
has a NULL .data member. That's a driver defect, and we don't want to
return -EINVAL, which is easy to ignore. We'd rather take the NULL pointer
dereference so we notice the problem and fix it.

Pull percpu fix from Tejun Heo:
"Douglas found and fixed a ref leak bug in percpu_ref_tryget[_live]().
The bug is caused by storing the return value of atomic_long_inc_not_zero()
into an int temp variable before returning it as a bool. The interim
cast to int loses the upper bits and can lead to false negatives. As
percpu_ref uses a high bit to mark a draining counter, this can happen
relatively easily.
Fixed by using bool for the temp variable"

Instead of keeping two levels of indirection for requests types, fold it
all into the operations. The little caveat here is that previously
cmd_type only applied to struct request, while the request and bio op
fields were set to plain REQ_OP_READ/WRITE even for passthrough
operations.
Instead this patch adds new REQ_OP_* for SCSI passthrough and driver
private requests, althought it has to add two for each so that we
can communicate the data in/out nature of the request.
