Currently arm_dma_remap returns the offset value when it fails

is wrong as the caller expects NULL on failure, and can result
in kernel panic on dereferencing the returned pointer.

A recent change to regulator framework replaced the
regulator_set_optimum_mode API with regulator_set_load.
The regulator_set_load API does the following for regulators which have
not implemented set_load().
- determines the most optimal mode for the given load by calling
get_optimum_mode()
- gets the current mode by calling get_mode()
- calls set_mode() if the modes are different and expects the mode to be
committed to the hardware
The rpm-smd-regulator's get_optimum_mode() remembers the load and uses that
for the upcoming get_mode() call. This causes the framework to never call
the set_mode API, thereby causing rpm-smd-regulator to never send the load
to the RPM.
The set_load op was introduced for hardware which does not support the
set_mode op. This is convenient since the RPM sets the mode according to
the aggregated load requirements. In addition the RPM also supports forcing
certain modes which fits well with the set_mode op.
Implement the set_load op to send the aggregated load vote to RPM, and
repurpose the set_mode op to send the aggregated mode vote to RPM.
Remove the get_optimum_mode op since it is no longer required with this
change.
Repurposing of set_mode should not impact consumers since it has the same
effect as before. Instead of sending a load vote which would cause the RPM
to select the desired mode the mode will be sent directly.
Furthermore, the hpm-min-load device tree property is no longer required
since the mode is no longer set based on the hpm-min-load threshold.
Remove it.

When cluster enters a low power mode, the mode entered is stored
in last_level. During LPM driver probe last_level is initialized
to default level, if a core in that cluster is online.
If all the cores in the cluster are hotplugged after initializing
the last_level and before the per cluster data structures are
initialized, cluster enters low power mode but does not update
last_level as the data structures are not available. In this case
when a core in this cluster is coming online and last_level indicates
default level, assumes cluster did not enter any low power mode,
the update of flags to reflect the cores as active for this cluster
does not happen. This makes driver to select system level low power
mode as if this cluster is in low power mode eventhough it is out
of low power mode.
To avoid this race, prevent cores hotplug during lpm probe.

CONFIG_FORCE_PAGES introduces a debug option to mark free
pages as read only in order to trigger a fault if any code
attempts to write to a page on the buddy list.
In order to achieve this it splits all section mappings in
to PAGE_SIZE pages during boot. While doing this split, it
wrongly allocates a pte (of page size) for each pmd. Linux
however in armv7 short descriptor format, uses same second
level pte for 2 consecutive pmds offset by the actual second
level table size. Refer comments in kernel file
arch/arm/include/asm/pgtable-2level.h for details.
Fix this by allocating pte for a section mapped pmd while
providing required offset if pte already exists.

Commit d0164adc89 ("mm, page_alloc: distinguish between being unable to
sleep, unwilling to sleep and avoiding waking kswapd") modified __GFP_WAIT
to explicitly identify the difference between atomic callers and those
that were unwilling to sleep. Later the definition was removed entirely.
The GFP_RECLAIM_MASK is the set of flags that affect watermark checking
and reclaim behaviour but __GFP_ATOMIC was never added. Without it, atomic
users of the slab allocator strip the __GFP_ATOMIC flag and cannot access
the page allocator atomic reserves. This patch addresses the problem.
The user-visible impact depends on the workload but potentially atomic
allocations unnecessarily fail without this path.
