irq_domain: Remove irq_domain_add_simple()
irq_domain_add_simple() was a stop-gap measure until complete irq_domain

This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it. This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

irq_domain: Add support for base irq and hwirq in legacy mappings
Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq)
so that a controller driver can allocate a fixed range of irq_descs and use
a simple calculation to translate back and forth between linux and hw irq
numbers. This is needed to use an irq_domain with many of the ARM interrupt
controller drivers that manage their own irq_desc allocations. Ultimately
the goal is to migrate those drivers to use the linear revmap, but doing it
this way allows each driver to be converted separately which makes the
migration path easier.
This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use
(first_irq-first_hwirq) as the offset between hwirq and linux irq number,
and adds checks to make sure that the hwirq number does not exceed range
assigned to the controller.

irq_domain: Replace irq_alloc_host() with revmap-specific initializers
Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.
This patch also adds a host_data argument to the generators. There are
cases where the host_data pointer will be needed before the function returns.
ie. the legacy map calls the .map callback for each irq before returning.
v2: - Add void *host_data argument to irq_domain_add_*() functions
- fixed failure to compile
- Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c

irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead
This patch drops the powerpc-specific irq_map table and replaces it with
directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating
and freeing irq_desc structures.
This patch is a preparation step for generalizing the powerpc-specific virq
infrastructure to become irq_domains.
As part of this change, the irq_big_lock is changed to a mutex from a raw
spinlock. There is no longer any need to use a spin lock since the irq_desc
allocation code is now responsible for the critical section of finding
an unused range of irq numbers.
The radix lookup table is also changed to store the irq_data pointer instead
of the irq_map entry since the irq_map is removed. This should end up being
functionally equivalent since only allocated irq_descs are ever added to the
radix tree.
v4: - Fix incorrect access to irq_data structure in debugfs code
- Don't ever allocate virq 0

irq_domain/powerpc: Use common irq_domain structure instead of irq_host
This patch drops the powerpc-specific irq_host structures and uses the common
irq_domain strucutres defined in linux/irqdomain.h. It also fixes all
the users to use the new structure names.
Renaming irq_host to irq_domain has been discussed for a long time, and this
patch is a step in the process of generalizing the powerpc virq code to be
usable by all architecture.
An astute reader will notice that this patch actually removes the irq_host
structure instead of renaming it. This is because the irq_domain structure
already exists in include/linux/irqdomain.h and has the needed data members.

trip points can be easily done as the registration API's return the
cooling device pointer.

thermal: Add a new trip type to use cooling device instance number
This patch adds a new trip type THERMAL_TRIP_STATE_ACTIVE. This
trip behaves same as THERMAL_TRIP_ACTIVE but also passes the cooling
device instance number. This helps the cooling device registered as
different instances to perform appropriate cooling action decision in
the set_cur_state call back function.
Also since the trip temperature's are in ascending order so some logic
is put in place to skip the un-necessary checks.

ARM: exynos: remove useless code to save/restore L2
Following the merge of CPU PM notifiers and L2 resume code, this patch
removes useless code to save and restore L2 registers.
This is now automatically covered by suspend calls which integrated
CPU PM notifiers and new sleep code that allows to resume L2 before MMU
is turned on.

This patch adds support AFTR(ARM OFF TOP RUNNING) mode in

sched: Ensure cpu_power periodic update
With a lot of small task, the softirq sched is nearly never called
when no_hz is enable. Te load_balance is mainly called with
the newly_idle mode which doesn't update the cpu_power.
Add a next_update field which ensure a maximum update period when
there is short activity

ARM: kprobes: work around build errors
I got a few build errors for kprobes playing with randconfig on the
latest kernel. While this patch manages to avoid these errors, I'm
pretty sure that it is not the ideal solution.
The errors I got in arm are while building for ARMv6 with
the arm-linux-gnueabihf-gcc-4.6 provided by Linaro, which
results in these messages:

usb: ehci: make HC see up-to-date qh/qtd descriptor ASAP
This patch introduces the helper of ehci_sync_mem to flush
qtd/qh into memory immediately on some ARM, so that HC can
see the up-to-date qtd/qh descriptor asap.
This patch fixs one performance bug on ARM Cortex A9 dual core
platform, which has been reported on quite a few ARM machines
(OMAP4, Tegra 2, snowball...), see details from link of
https://bugs.launchpad.net/bugs/709245.
The patch has been tested ok on OMAP4 panda A1 board, and the
performance of 'dd' over usb mass storage can be increased from
4~5MB/sec to 14~16MB/sec after applying this patch.
