Since the smp_mb__{before,after}*() ops are fundamentally dependent on
how an arch can implement atomics it doesn't make sense to have 3
variants of them. They must all be the same.

Furthermore, the 3 variants suggest they're only valid for those 3
atomic ops, while we have many more where they could be applied.

So move away from
smp_mb__{before,after}_{atomic,clear}_{dec,inc,bit}() and reduce the
interface to just the two: smp_mb__{before,after}_atomic().

This patch prepares the way by introducing default implementations in
asm-generic/barrier.h that default to a full barrier and providing
__deprecated inlines for the previous 6 barriers if they're not
provided by the arch.

This should allow for a mostly painless transition (lots of deprecated
warns in the interim).

The IPMI driver would wake up periodically looking for events and
watchdog pretimeouts.  If there is nothing waiting for these events,
it's really kind of pointless to be checking for them.  So modify the
driver so the message handler can pass down if it needs the lower layer
to be waiting for these.  Modify the system interface lower layer to
turn off all timer and thread activity if the upper layer doesn't need
anything and it is not currently handling messages.  And modify the
message handler to not restart the timer if its timer is not needed.

The timers and kthread will still be enabled if:
 - the SI interface is handling a message.
 - a user has enabled watching for events.
 - the IPMI watchdog timer is in use (since it uses pretimeouts).
 - the message handler is waiting on a remote response.
 - a user has registered to receive commands.

This mostly affects interfaces without interrupts.  Interfaces with
interrupts already don't use CPU in the system interface when the
interface is idle.

With recent changes it is possible for the timer handler to detect an
idle interface and not start the timer, but the thread to start an
operation at the same time.  The thread will not start the timer in that
instance, resulting in the timer not running.

Instead, move all timer operations under the lock and start the timer in
the thread if it detect non-idle and the timer is not already running.
Moving under locks allows the last timeout to be set in both the thread
and the timer.  'Timer is not running' means that the timer is not
pending and smi_timeout() is not running.  So we need a flag to detect
this correctly.

Also fix a few other timeout bugs: setting the last timeout when the
interrupt has to be disabled and the timer started, and setting the last
timeout in check_start_timer_thread possibly racing with the timer

At the moment the "Device Drivers / Graphics support" kernel config page
looks rather messy, with DRM and fbdev driver selections on the same
page, some on the top level Graphics support page, some under their
respective subsystems.

If I'm not mistaken, this is caused by the drivers depending on other
things than DRM or FB, which causes Kconfig to arrange the options in
not-so-neat manner.

Both DRM and FB have a main menuconfig option for the whole DRM or FB
subsystem. Optimally, this would be enough to arrange all DRM and FB
options under the respective subsystem, but for whatever reason this
doesn't work reliably.

This patch adds an explicit submenu for DRM and FB, making it much
clearer which options are related to FB, and which to DRM.

Pull pincontrol fixes from Linus Walleij:
 "A first set of pin control fixes for the v3.15 series:

   - Fix a couple of barnsjukdomar on the Rockchip driver.

   - Remove an idiotic debug print I happened to leave behind in the
     Nomadik driver.

   - Fixup the Qualcomm MSM interrupt handling code for the TLMM v2.

   - Three patches renaming the Broadcom Capri driver to BCM28155.  This
     has been falling between the chairs for some time due to some
     cross-tree synchronization misunderstandings, now I'm fed up with
     this and just rename it in this -rc1 phase"
