de25cfcb64 m68k: remove old ColdFire IO access support code
All the ColdFire IO access support code has been moved to io_no.h.
This means that all ColdFire support is at least now consistent no
matter whether the MMU is enabled or not for them.

Now that io_mm.h has reverted to only support the traditional m68k MMU
enabled processors we can remove the ColdFire specific definitions.

We can also remove the old ColdFire PCI bus IO access functions.
The new io_no.h uses asm-generic/io.h to provide all the basic support.

dfbc5cb399 m68k: use io_no.h for MMU and non-MMU enabled ColdFire
Use the io_no.h IO access support for all ColdFire systems, no matter
whether configured with MMU enabled or disabled. Previously there was
subtle differences in IO access functions used in both cases, and these
resulted in broken behavior for some drivers.

As observed and reported by Angelo when using MMU enabled systems the
read/write family of functions was using little endian access, while the
non-MMU enabled systems were using native endian. This results in drivers
that are shared across Freescale processors (for some of the common
internal SoC peripherals) not working - since they are wired up for native
endian access.

This problem brings to light issues with PCI bus access and local
peripheral access - but these are not addressed with this fix.

927c28c252 m68k: setup PCI support code in io_no.h
Ultimately we want the ColdFire IO access support to be consisent no matter
whether it is configured with MMU enabled or disabled. To acheive that we
need to get all the ColdFire IO access support code together in one place,
in this case io_no.h. The last big piece not in io_no.h is the PCI bus
support functions.

Define the IO mapping addresses required to use the asm-generic IO
access functions. They can provide everything we need - no need for us
to duplicate or have local in/out or read/write access functions.
Note that this support is not active yet, since we haven't done the
full switch over to using the asm-generic functions yet. And also note
that we do not yet remove the old PCI functions from io_mm.h yet.

Consolodating all this IO access support in a single place will make
it easier in the future to enable PCI bus support for non-MMU enabled
ColdFire (which we currently cannot do).

9746882f54 m68k: group io mapping definitions and functions
Create a new header file, kmap.h, that groups all the definitions and
functions associated with the io mapping and remapping.

Currently the functions are spread across raw_io.h and io_mm.h. And in
the future we will want to use these in io_no.h as well. So it makes
sense to move them all together into a single header file.

It is named after the arch/m68k/mm/kmap.c file that actually implements
many of the exported functions.

4478048b44 m68k: rework raw access macros for the non-MMU case
The primary and fundamental access macros are really the __raw versions.
So make them the actual implementation for access, and not the read/write
access macros. The read/write macros and functions are built on top of
the raw access (with byte swapping or other actions as required).

This in itself causes no functional change right now. But it will make it
easier to fix and resolve problems with PCI bus access in the future.

d97cf70af0 m68k: use asm-generic/io.h for non-MMU io access functions
There is nothing really special about the non-MMU m68k IO access functions.
So we can easily switch to using the asm-generic/io.h functions.

The only thing we do need to handle is that historically the m68k IO access
functions for readw/readl/writew/writel use native CPU endian ordering. So
for us on m68k/ColdFire that means they are big-endian. Leave the existing
set of _raw_read/__raw_write and read/write macros in place to deal with
them. (They are ripe for later cleanup, but that is for another patch).

The non-MMU and ColdFire IO access functions will be moving to using the

eccb4422cf smb3: Add ftrace tracepoints for improved SMB3 debugging
Although dmesg logs and wireshark network traces can be
helpful, being able to dynamically enable/disable tracepoints
(in this case via the kernel ftrace mechanism) can also be
helpful in more quickly debugging problems, and more
selectively tracing the events related to the bug report.

This patch adds 12 ftrace tracepoints to cifs.ko for SMB3 events
in some obvious locations.  Subsequent patches will add more
as needed.

Example use:
   trace-cmd record -e cifs
   <run test case>
   trace-cmd show

Various trace events can be filtered. See:
       trace-cmd list | grep cifs
for the current list of cifs tracepoints.

Sample output (from mount and writing to a file):

3d4ef9a153 smb3: fix redundant opens on root
In SMB2/SMB3 unlike in cifs we unnecessarily open the root of the share
over and over again in various places during mount and path revalidation
and also in statfs.  This patch cuts redundant traffic (opens and closes)
by simply keeping the directory handle for the root around (and reopening
it as needed on reconnect), so query calls don't require three round
trips to copmlete - just one, and eases load on network, client and
server (on mount alone, cuts network traffic by more than a third).

Also add a new cifs mount parm "nohandlecache" to allow users whose
servers might have resource constraints (eg in case they have a server
with so many users connecting to it that this extra handle per mount
could possibly be a resource concern).

8767712f26 rmdir(),rename(): do shrink_dcache_parent() only on success
Once upon a time ->rmdir() instances used to check if victim inode
had more than one (in-core) reference and failed with -EBUSY if it
had.  The reason was race avoidance - emptiness check is worthless
if somebody could just go and create new objects in the victim
directory afterwards.

With introduction of dcache the checks had been replaced with
checking the refcount of dentry.  However, since a cached negative
lookup leaves a negative child dentry, such check had lead to false
positives - with empty foo/ doing stat foo/bar before rmdir foo
ended up with -EBUSY unless the negative dentry of foo/bar happened
to be evicted by the time of rmdir(2).  That had been fixed by
doing shrink_dcache_parent() just before the refcount check.

At the same time, ext2_rmdir() has grown a private solution that
eliminated those -EBUSY - it did something (setting ->i_size to 0)
which made any subsequent ext2_add_entry() fail.

Unfortunately, even with shrink_dcache_parent() the check had been
racy - after all, the victim itself could be found by dcache lookup
just after we'd checked its refcount.  That got fixed by a new
helper (dentry_unhash()) that did shrink_dcache_parent() and unhashed
the sucker if its refcount ended up equal to 1.  That got called before
->rmdir(), turning the checks in ->rmdir() instances into "if not
unhashed fail with -EBUSY".  Which reduced the boilerplate nicely, but
had an unpleasant side effect - now shrink_dcache_parent() had been
done before the emptiness checks, leading to easily triggerable calls
of shrink_dcache_parent() on arbitrary large subtrees, quite possibly
nested into each other.

Several years later the ext2-private trick had been generalized -
(in-core) inodes of dead directories are flagged and calls of
lookup, readdir and all directory-modifying methods were prevented
in so marked directories.  Remaining boilerplate in ->rmdir() instances
became redundant and some instances got rid of it.

In 2011 the call of dentry_unhash() got shifted into ->rmdir() instances
and then killed off in all of them.  That has lead to another problem,
though - in case of successful rmdir we *want* any (negative) child
dentries dropped and the victim itself made negative.  There's no point
keeping cached negative lookups in foo when we can get the negative
lookup of foo itself cached.  So shrink_dcache_parent() call had been
restored; unfortunately, it went into the place where dentry_unhash()
used to be, i.e. before the ->rmdir() call.  Note that we don't unhash
anymore, so any "is it busy" checks would be racy; fortunately, all of
them are gone.

We should've done that call right *after* successful ->rmdir().  That
reduces contention caused by tree-walking in shrink_dcache_parent()
and, especially, contention caused by evictions in two nested subtrees
going on in parallel.  The same goes for directory-overwriting rename() -
the story there had been parallel to that of rmdir().

a0504aecba PM / runtime: Drop usage count for suppliers at device link removal
In the case consumer device is runtime resumed, while the link to the
supplier is removed, the earlier call to pm_runtime_get_sync() made from
rpm_get_suppliers() does not get properly balanced with a corresponding
call to pm_runtime_put(). This leads to that suppliers remains to be
runtime resumed forever, while they don't need to.

Let's fix the behaviour by calling rpm_put_suppliers() when dropping a
device link. Not that, since rpm_put_suppliers() checks the
link->rpm_active flag, we can correctly avoid to call pm_runtime_put() in
cases when we shouldn't.

1e83786198 PM / runtime: Fixup reference counting of device link suppliers at probe
In the driver core, before it invokes really_probe() it runtime resumes the
suppliers for the device via calling pm_runtime_get_suppliers(), which also
increases the runtime PM usage count for each of the available supplier.

This makes sense, as to be able to allow the consumer device to be probed
by its driver. However, if the driver decides to add a new supplier link
during ->probe(), hence updating the list of suppliers, the following call
to pm_runtime_put_suppliers(), invoked after really_probe() in the driver
core, we get into trouble.

More precisely, pm_runtime_put() gets called also for the new supplier(s),
which is wrong as the driver core, didn't trigger pm_runtime_get_sync() to
be called for it in the first place. In other words, the new supplier may
be runtime suspended even in cases when it shouldn't.

Fix this behaviour, by runtime resume suppliers according to the same
conditions as managed by the runtime PM core, when runtime resume callbacks
are being invoked.

Additionally, don't try to runtime suspend any of the suppliers after
really_probe(), but instead rely on that to happen via the consumer device,
when it becomes runtime suspended.

c1a957d170 PM / suspend: Prevent might sleep splats
timekeeping suspend/resume calls read_persistent_clock() which takes
rtc_lock. That results in might sleep warnings because at that point
we run with interrupts disabled.

We cannot convert rtc_lock to a raw spinlock as that would trigger
other might sleep warnings.

As a workaround we disable the might sleep warnings by setting
system_state to SYSTEM_SUSPEND before calling sysdev_suspend() and
restoring it to SYSTEM_RUNNING afer sysdev_resume(). There is no lock
contention because hibernate / suspend to RAM is single-CPU at this
point.

In s2idle's case the system_state is set to SYSTEM_SUSPEND before
timekeeping_suspend() which is invoked by the last CPU. In the resume
case it set back to SYSTEM_RUNNING after timekeeping_resume() which is
invoked by the first CPU in the resume case. The other CPUs will block
on tick_freeze_lock.

84eaaef2ae ALSA: dice: unuse second stream for MIDI conformant data channel for TC Electronic models
At present, all of models produced by TC Electronic except for Konnekt Live
are supported with hard-coded their stream formats. Studio Konnekt 48 is
sore model to support dual streams for both directions. The second stream
has no MIDI conformant data channel in its data block. But current
implementation transfers the second stream with MIDI conformant data
channel.

This commit fixes this issue.

1ceb506d63 ALSA: dice: fix stream format parameters for TC Electronic Studio Konnekt 48
TC Electronic Studio Konnekt 48 is an application of combination of
WaveFront Dice II STD and TC Applied Technologies (TCAT) TCD2210 (Dice
Mini). The latter is on a board with BNC and optical interfaces, thus
used for signal processing for word clock, S/PDIF and ADAT. This model
doesn't support TCAT extended application protocol. For such devices,
ALSA dice driver needs to have hard-coded parameters for stream formats.

This commit fixes stream format parameters for this model. Unfortunately, at
sampling transmission frequencies over 48.0kHz, I confirmed that current
ALSA dice driver doesn't drive the device appropriately to generate sounds
(silence). I guess that this comes from timestamping quirk of Dice-based
devices, which I reported.

f59c303b59 ARM: Fix i2c-gpio GPIO descriptor tables
I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".

But several had it set to >=0 which gives the names
