CONFIG_COMPAT_BRK disables the heap randomization which is only needed
for very old and ancient user space applications, I am not aware that we
run any of these, just deactivate this option for these targets to allow
heap randomization.

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

The samsung target deactivates some options which are activated in the
generic kernel configuration. This looks unnecessary to me, so remove
this. This also fixes build problem found by build bot, for example the
kmod-fs-nfs-v3 was not building, because CONFIG_NETWORK_FILESYSTEMS was
deactivated.
