This plugs in clkdev lookups for the SH7786 clocks and migrates off of
clock string usage for the TMU clocks.
Previously the TMU clocks were aliased to the peripheral clock, so this
gets the driver actually toggling the proper clocks now as well.

We want to get rid of the clock string from platform data entirely,
depending on the clkdev-based clock lookup to do the right thing for us
instead.
This converts all of the SH drivers to request their associated function
clocks directly, and if there is no match for that then we fall back on
the legacy lookup while warning about it. After all of the outstanding
CPUs have been converted to clkdev lookups the clock string will be
killed off completely.

This is just a simple refactoring patch on top of the early dev_name()
support, converting from kstrdup() to kasprintf() as suggested by Kay.

This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.
As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.

Now that dev_name() can be used early, we no longer require a static

There is no need to copy in the name from the sh timer config now that
dev_name() is available early. We prefer the dev_name() variant for
consistent naming.

Presently early platform devices suffer from the fact they are unable to
use dev_xxx() calls early on due to dev_name() and others being
unavailable at the time ->probe() is called.
This implements early init_name construction from the matched name/id
pair following the semantics of the late device/driver match. As a
result, matched IDs (inclusive of requested ones) are preserved when the
handoff from the early platform code happens at kobject initialization
time.
Since we still require kmalloc slabs to be available at this point, using
kstrdup() for establishing the init_name works fine. This subsequently
needs to be tested from dev_name() prior to the init_name being cleared
by the driver core. We don't kfree() since others will already have a
handle on the string long before the kobject initialization takes place.
This is also needed to permit drivers to use the clock framework early,
without having to manually construct their own device IDs from the match
id/name pair locally (needed by the early console and timer code on sh
and arm).

early platform devices and the like may need to set up clock aliases,
which require an allocation at a time well before the slab allocators
are available. The clock framework comes up after bootmem, so using
bootmem as a fallback should be sufficient.

This rolls in the remainder of the clkdev API bits from the ARM tree.
This can more or less be used verbatim, so we just copy it over and nuke
our local version.

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".
When the callback is called for special messages, the driver creates
an uevent for the received message. The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.
udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.

This hooks up the ->set_affinity() for the INTC controllers, which can be
done as just a simple copy of the cpumask. The enable/disable paths
already handle SMP register strides, so we just test the affinity mask in
these paths to determine which strides to skip over.
The early enable/disable path happens prior to the IRQs being registered,
so we have no affinity mask established at that point, in which case we
just default to CPU_MASK_ALL. This is left as it is to permit the force
enable/disable code to retain existing semantics.

In the future, we are going to be changing the lock type for struct
device (once we get the lockdep infrastructure properly worked out) To
make that changeover easier, and to possibly burry the lock in a
different part of struct device, let's create some functions to lock and
unlock a device so that no out-of-core code needs to be changed in the
future.
This patch creates the device_lock/unlock/trylock() functions, and
converts all in-tree users to them.

The vfs depends upon filesystem methods to update the
vfs inode. Sysfs adds to the normal number of places
where the vfs inode is updated by also updatng the
vfs inode in sysfs_refresh_inode.
Typically the inode mutex is used to serialize updates
to the vfs inode, but grabbing the inode mutex in
sysfs_permission and sysfs_getattr causes deadlocks,
because sometimes the vfs calls those operations with
the inode mutex held. Therefore sysfs can not use the
inode mutex to serial updates to the vfs inode.
The sysfs_mutex is acquired in all of the routines
where sysfs updates the vfs inode, and with a small
change we can consistently protext sysfs vfs inode
updates with the sysfs_mutex. To protect the sysfs
vfs inode updates with the sysfs_mutex simply requires
extending the scope of sysfs_mutex in sysfs_setattr
over inode_setattr, and over inode_change_ok (so we
have an unchanging inode when we perform the check).
