In case of IOMMU memory needs to only be flushed when it is
unmapped and not mappped. Also, when an application is running
the number of unmaps would in most cases be less than number of
maps, so this way the number of flushes wil be fewer.

1. Verifying if the size of memory allocation in ion_alloc() is aligned
by PAGE_SIZE at least. If it is not, this change makes the size to be
aligned by PAGE_SIZE.
2. Unmaps all mappings to the kernel and DMA address spaces when
destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
those virtual address spaces.
3. Makes the return value of ion_alloc() to be explicit Linux error code
when it fails to allocate a buffer.
4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
relavant call to ion_buffer_put().
5. Checks if the task is valid before calling put_task_struct() due
to failure on creating a ion client in ion_client_create().
6. Returns error when buffer allocation requested by userspace is failed.

The auto_off feature loops through all clocks in lateinit and disables
them if their reference count is 0, so long as the SKIP_AUTO_OFF flag
is not set. This has a significant functional overlap with the more
intelligent handoff feature.
In addition to detecting initial clock rates, handoff (like auto_off)
disables clocks in lateinit, but only if the clock was detected to be
on when the handoff op was called during msm_clock_init.
Currently, handoff does not support a skip flag like SKIP_AUTO_OFF,
which was used aggressively by proc_comm targets. Experimentally,
however, this does not seem to cause problems, possibly because
clocks are now being more selectively disabled.
Because there is no up-to-date documentation of the reasons why many
of these flags were set, the flags are just dropped by this patch
until their questionable utility can be re-evaluated.

The original intent of disallowing voltage set across cpus is to prevent
setting of voltages on a core when its idle thread. The cpufreq
framework ensures that the frequency changes and hence the voltage
changes happens on the respective cpus. By allowing setting of voltages
from others cpus, the secondary cores can be brought out of reset by the
non-primary CPUs after boot and thereby help mitigate any thermal issues
associated wth multicores.
The regulator framework that calls into msm_spm_set_vdd provides the
necessary access restrictions to prevent simultaneous calls into
msm_spm_set_vdd.And hence the spinlocks around the set_vdd calls have
been removed.

The Contiguous Memory Allocator is a set of helper functions for DMA
mapping framework that improves allocations of contiguous memory chunks.
CMA grabs memory on system boot, marks it with MIGRATE_CMA migrate type
and gives back to the system. Kernel is allowed to allocate only movable
pages within CMA's managed memory so that it can be used for example for
page cache when DMA mapping do not use it. On
dma_alloc_from_contiguous() request such pages are migrated out of CMA
area to free required contiguous block and fulfill the request. This
allows to allocate large contiguous chunks of memory at any time
assuming that there is enough free memory available in the system.
This code is heavily based on earlier works by Michal Nazarewicz.
