This reverts commit 8bb334401c
("kernel: lib: allow larger stack frame size for KASan").
Stack frame size set to 5600 to fix compilation error/s if
KASAN enabled by the commit 8bb334401c ("kernel: lib: allow
larger stack frame size for KASan") in 3.18 Kernel and same
commit got pulled into Kernel 4.4, which replaced stack
frame size 0 with 5600 as part of resolution of merge conflict.
But, by setting stack frame size to 0 will ignore stack frame
size warnings and so the compilation errors. So, revert commit
to fix below error while compiling Kernel 4.4 with KASAN enabled
and GCC 5.1 compiler.

* Removed spinlock as it was not locking against anything
* Removed conversion of interrupt status to error number
as it is not used by API client, and in case several bits are
set only 1 error is ever handled and the rest get lost.
Instead pass to the client the complete status.
* Removed redundant includes, variables
* vops structure is returned after performing a lookup in the DTS.
There's no need for that as we already know the structure
to return.

clk_get_sys was updated to return EPROBE_DEFER because on the
older kernel returning ENOENT was causing drivers that probed
before the clock provider to fail instead of deferring. The new
kernel version fixes this by returning EPROBE_DEFER in
__of_clk_get_from_provider. Thus, clk_get_sys failing means that
the clock provider exists, but the requested clock is not defined
in the provider, in which case ENOENT is a more appropriate error
code to return.

Since the IOMMU debug and test framework relies on parsing `iommus'
properties from the device tree, we've relied on setting an `iommus'
property directly on a few of our IOMMUs, just to ensure that the
debugfs directory gets populated even when client drivers haven't been
enabled. However, in newer kernels, any device node with an `iommus'
property gets auto-attached to the given IOMMU, which isn't actually
what we want to have happen. The end result is that we try to map our
own page table memory into an IOMMU, resulting in a recursive mapping
loop, which is unequivocally bad.
Fix this by removing the recursive `iommus' property. The method for
testing these things in isolation from clients will need to be
re-worked.

Add a cma pcp list in order to increase cma memory utilization.
Increased cma memory utilization will improve overall memory
utilization because free cma pages are ignored when memory reclaim
is done with gfp mask GFP_KERNEL.
Since most memory reclaim is done by kswapd, which uses a gfp mask
of GFP_KERNEL, by increasing cma memory utilization we are therefore
ensuring that less aggressive memory reclaim takes place.
Increased cma memory utilization will improve performance,
for example it will increase app concurrency.

CMA pages are designed to be used as fallback for movable allocations
and cannot be used for non-movable allocations. If CMA pages are
utilized poorly, non-movable allocations may end up getting starved if
all regular movable pages are allocated and the only pages left are
CMA. Always using CMA pages first creates unacceptable performance
problems. As a midway alternative, use CMA pages for certain
userspace allocations. The userspace pages can be migrated or dropped
quickly which giving decent utilization.
