To facilitate additional options to get_user_pages_fast() change the
singular write parameter to be gup_flags.
This patch does not change any functionality. New functionality will
follow in subsequent patches.
Some of the get_user_pages_fast() call sites were unchanged because they
already passed FOLL_WRITE or 0 for the write parameter.
NOTE: It was suggested to change the ordering of the get_user_pages_fast()
arguments to ensure that callers were converted. This breaks the current
GUP call site convention of having the returned pages be the final
parameter. So the suggestion was rejected.

Pull Wimplicit-fallthrough updates from Gustavo A. R. Silva:
"Mark switch cases where we are expecting to fall through.
This is part of the ongoing efforts to enable -Wimplicit-fallthrough.
Most of them have been baking in linux-next for a whole development
cycle. And with Stephen Rothwell's help, we've had linux-next
nag-emails going out for newly introduced code that triggers
-Wimplicit-fallthrough to avoid gaining more of these cases while we
work to remove the ones that are already present.
We are getting close to completing this work. Currently, there are
only 32 of 2311 of these cases left to be addressed in linux-next. I'm
auditing every case; I take a look into the code and analyze it in
order to determine if I'm dealing with an actual bug or a false
positive, as explained here:
https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/
While working on this, I've found and fixed the several missing
break/return bugs, some of them introduced more than 5 years ago.
Once this work is finished, we'll be able to universally enable
"-Wimplicit-fallthrough" to avoid any of these kinds of bugs from
entering the kernel again"

Pull mmiowb removal from Will Deacon:
"Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
Remove mmiowb() from the kernel memory barrier API and instead, for
architectures that need it, hide the barrier inside spin_unlock() when
MMIO has been performed inside the critical section.
The only relatively recent changes have been addressing review
comments on the documentation, which is in a much better shape thanks
to the efforts of Ben and Ingo.
I was initially planning to split this into two pull requests so that
you could run the coccinelle script yourself, however it's been plain
sailing in linux-next so I've just included the whole lot here to keep
things simple"

The "(&ctio->u.status1.sense_data)[i]" where i >= 0 expressions in
qlt_send_resp_ctio() are probably typos and should have been
"(&ctio->u.status1.sense_data[4 * i])" instead. Instead of only fixing
these typos, modify the code for storing sense data such that it becomes
easy to read. This patch fixes a Coverity complaint about accessing an
array outside its bounds.

Since fc_remote_port_delete() must be called with interrupts enabled, do
not disable interrupts when calling that function. Remove the lockin calls
from around the put_sess() call. This is safe because the function that is
called when the final reference is dropped, qlt_unreg_sess(), grabs the
proper locks. This patch avoids that lockdep reports the following:

In the *_done() functions, instead of returning early if sp->ref_count >=

depending on the completion status of the firmware abort. Remove srb.cwaitq

Remove the function qlt_abort_cmd_on_host_reset() because it can do the
following, all of which can cause a kernel crash:
- DMA unmapping while DMA is in progress.
- Call target_execute_cmd() while DMA is in progress.
- Call transport_generic_free_cmd() while the LIO core owns a command.
Instead of trying to abort a command asynchronously, set the 'aborted' flag
and handle the abort after the hardware has passed control back to the
tcm_qla2xxx driver.

It is important to know why a firmware command failed. Hence log 'rval'
together with the values of the mailbox registers if a firwmare command
fails.

rport pointer
Since Coverity cannot know that rport != NULL in qla2xxx_queuecommand() and
since there is code in that function that dereferences the rport pointer,
modify qla2xxx_queuecommand() such that it fails SCSI commands if rport ==
NULL.

Testing whether a pointer is not NULL after it has been dereferenced is not
useful. Hence remove the if (fcport) test. This was detected by Coverity.

Since qla2x00_init_timer() is not used for I/O commands there is no need to
inline this function. Hence uninline this function.

The previous patch moved all qla2x00_is_reserved_id() callers into
qla_init.c. Hence also move the qla2x00_is_reserved_id() definition into
qla_init.c.

Since all qla2x00_find_new_loop_id() calls occur in the same source file as
the definition of this function, move that function to just before its
first caller and declare it static. Convert the header above this function
into kernel-doc format.

Change one occurrence of "*(" into "()" and change one occurrence of
"lcoate" into "locate". Fix the reference to qla_tgt_handle_cmd_for_atio():
there has never been a function with that name.
