Adding a flag for tegra_disable_clean_inv_dcache to flush cache as LoUIS
or ALL. After this patch, the v7_flush_dcache_louis is used for CPU hotplug
and CPU suspend in CPU power down (e.g. CPU idle power-down mode) case. And
the v7_flush_dcache_all is used for CPU cluster power down (e.g. suspend to
LP2 mode).

The v7_invalidate_l1 was used for the L1 cache that come out from reset
in a undefined state. This is no need for Cortex-A15. We do it for A9
only.

This supports CPU core power down on each CPU when CPU idle. When CPU go
into this state, it saves it's context and needs a proper configuration
in flow controller to power gate the CPU when CPU runs into WFI
instruction. And the CPU also needs to set the IRQ as CPU power down idle
wake up event in flow controller.

The flow controller would take care the power sequence when CPU idle in
powered-down mode. It powered gate the CPU when CPU runs into WFI
instruction. And wake up the CPU when event be triggered.
The sequence is below.
* setting wfi bitmap for the CPU as the halt event in the
FLOW_CTRL_CPU_HALT_REG to monitor the CPU running into WFI,then power
gate it
* setting IRQ and FIQ as wake up event to wake up CPU when event triggered

There is a difference between GICv1 and v2 when CPU in power management
mode (aka CPU power down on Tegra). For GICv1, IRQ/FIQ interrupt lines
going to CPU are same lines which are also used for wake-interrupt.
Therefore, we cannot disable the GIC CPU interface if we need to use same
interrupts for CPU wake purpose. This creates a race condition for CPU
power off entry. Also, in GICv1, disabling GICv1 CPU interface puts GICv1
into bypass mode such that incoming legacy IRQ/FIQ are sent to CPU, which
means disabling GIC CPU interface doesn't really disable IRQ/FIQ to CPU.
GICv2 provides a wake IRQ/FIQ (for wake-event purpose), which are not
disabled by GIC CPU interface. This is done by adding a bypass override
capability when the interrupts are disabled at the CPU interface. To
support this, there are four bits about IRQ/FIQ BypassDisable in CPU
interface Control Register. When the IRQ/FIQ not being driver by the
CPU interface, each interrupt output signal can be deasserted rather
than being driven by the legacy interrupt input.
So the wake-event can be used as wakeup signals to SoC (system power
controller).
To prevent race conditions and ensure proper interrupt routing on
Cortex-A15 CPUs when they are power-gated, add a CPU PM notifier
call-back to reprogram the GIC CPU interface on PM entry. The
GIC CPU interface will be reset back to its normal state by
the common GIC CPU PM exit callback when the CPU wakes up.

This reverts commit 510bb59 "ARM: tegra: add cpu_disable for hotplug".
The Tegra114 support CPU0 hotplug function in HW physically, but it needs
other software to make it work normally after we add CPU idle power down
mode support. So remove them for now.

The watchdog infrastructure in Dove is no different from that in
Orion5x or Kirkwood, so let's enable it for Dove. The only things
missing are a few register settings in Dove's bridge-regs.h.

and BRIDGE_CAUSE registers, move the definitions into the watchdog
driver itself.

Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu
interrupt (usually interrupt #30), and the GIC configuration should flag it as
such. With this setup, request_irq() should fail, and the right API is
request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq().
Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the
right CPU.
There are no users of this driver since a long time and it makes more sense to
get rid of it as nobody is looking to fix it.
In case somebody wakes up after this has been removed and needs it, please
revert this driver and pick these updates (These were never pushed to mainline):

Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
support receiving on multiple UDP ports.
10) Major cleanups, particular in the area of debugging and cookie
lifetime handline, to the SCTP protocol code. From Daniel
Borkmann.
11) Allow packets to cross network namespaces when traversing tunnel
devices. From Nicolas Dichtel.
12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
manner akin to how we monitor real network traffic via ptype_all.
From Daniel Borkmann.

from Johannes Berg.
14) Fix scalability issues in the netem packet scheduler's time queue,
by using an rbtree. From Eric Dumazet.
15) Several bug fixes in TCP loss recovery handling, from Yuchung
Cheng.
16) Add support for GSO segmentation of MPLS packets, from Simon
Horman.
17) Make network notifiers have a real data type for the opaque
pointer that's passed into them. Use this to properly handle
network device flag changes in arp_netdev_event(). From Jiri
Pirko and Timo Teräs.
18) Convert several drivers over to module_pci_driver(), from Peter
Huewe.
19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
O(1) calculation instead. From Eric Dumazet.
20) Support setting of explicit tunnel peer addresses in ipv6, just
like ipv4. From Nicolas Dichtel.
21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
22) Prevent a single high rate flow from overruning an individual cpu
during RX packet processing via selective flow shedding. From
Willem de Bruijn.
23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
Dumazet.
24) Don't just drop GSO packets which are above the TBF scheduler's
burst limit, chop them up so they are in-bounds instead. Also
from Eric Dumazet.
25) VLAN offloads are missed when configured on top of a bridge, fix
from Vlad Yasevich.
26) Support IPV6 in ping sockets. From Lorenzo Colitti.
27) Receive flow steering targets should be updated at poll() time
too, from David Majnemer.
28) Fix several corner case regressions in PMTU/redirect handling due
to the routing cache removal, from Timo Teräs.
29) We have to be mindful of ipv4 mapped ipv6 sockets in
upd_v6_push_pending_frames(). From Hannes Frederic Sowa.
30) Fix L2TP sequence number handling bugs, from James Chapman."

Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong

Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the

AMD finally released the dynamic power management code for all their

also a huge amount of code, in fact it is most of this pull request.

sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostly
I've been banging on this quite a lot due to the size of it, and it
seems to okay on everything I've tested it on."

When the local timer freq changed, the twd_update_frequency function
should be run all the CPUs include itself, otherwise, the twd freq will
not get updated and the local timer will not run correcttly.
smp_call_function will run functions on all other CPUs, but not include
himself, this is not correct,use on_each_cpu instead to fix this issue.

imx_v6_v7_defconfig handles both multi-core and single-core SoCs, and it has CONFIG_SMP=y selected by default.
With such config we cannot select ARM_ERRATA_364296, as it depends on !SMP.
Let ARM_ERRATA_364296 be undependent on CONFIG_SMP, so that we can select this erratum for the ARM1136 SoCs, even if CONFIG_SMP=y is enabled.

Failure to add the mapping created in debug_ll_io_init() can lead
to the BUG_ON() triggering in lib/ioremap.c:27 if the static
virtual address decided for the debug_ll mapping overlaps with
another mapping that is created later. This happens because the
generic ioremap code has no idea there is a mapping there and it
tries to place a mapping in the same location and blows up when
it sees that there is a pte already present.

Macro __INIT is used to place various code in head-common.S into the init
section. This should be matched by a closing __FINIT. Also, add an
explicit ".text" to ensure subsequent code is placed into the correct
section; __FINIT is simply a closing marker to match __INIT and doesn't
guarantee to revert to .text.
This historically caused no problem, because macro __CPUINIT was used at
the exact location where __FINIT was missing, which then placed following
code into the cpuinit section. However, with commit 22f0a2736 "init.h:
remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a
no-op, thus leaving all this code in the init section, rather than the
regular text section. This caused issues such as secondary CPU boot
failures or crashes.

As pointed out by Arnd Bergmann there is a get_signal macro definied in
linux/signal.h which can conflict with the platform data callback
function of the same name leading to confusing errors from the compiler
(especially if signal.h manages to get pulled into the driver itself due
to header dependencies). Avoid such errors by renaming get_signal and
put_signal in the platform data to get_xfer_signal and put_xfer_signal.

Pull device tree updates from Grant Likely:
"This branch contains the following changes:
- Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
- Remove #ifdef from linux/of_platform.h to increase compiler syntax
coverage
- Bug fix for address decoding on Bimini and js2x powerpc platforms.
- miscellaneous binding changes
One note on the above. The binding changes going in from all kinds of
different trees has gotten rather out of hand. I picked up some
during this cycle, but even going though my tree isn't a great fit.
Ian Campbell has prototyped splitting the bindings and .dtb files into
a separate repository. The plan is to migrate to using that sometime
in the next few kernel releases which should get rid of a lot of the
churn on binding docs and .dts files"

Pull input updates from Dmitry Torokhov:
"First round of updates for the input subsystem.
You will get a new touchsreen driver for Cypress 4th generation
devices, a driver for a special controller implementing PS/2 protocol
in OLPC devices, and a driver for power key for SiRFprimaII PWRC.
HID and bcm5497 now support for the 2013 MacBook Air.
EVIOCGKEY and the rest of evdev ioctls now flush events of matching
type from the client's event queue so that clients can be sure any
events received after issuing EVIOCG* ioctl are new events.
And a host of cleanups and improvements in other drivers"
