ARM: constify machine_desc structure uses struct machine_desc records are defined everywhere as a 'const' structure, but unfortuantely it loses its const-ness through the use of linker magic - the symbols which surround the section are not declared const so it becomes possible not to use 'const' for pointers to these const structures. Let's fix this oversight - all pointers to these structures should be marked const too.

ARM: Add arm_memblock_steal() to allocate memory away from the kernel Several platforms are now using the memblock_alloc+memblock_free+ memblock_remove trick to obtain memory which won't be mapped in the kernel's page tables. Most platforms do this (correctly) in the ->reserve callback. However, OMAP has started to call these functions outside of this callback, and this is extremely unsafe - memory will not be unmapped, and could well be given out after memblock is no longer responsible for its management. So, provide arm_memblock_steal() to perform this function, and ensure that it panic()s if it is used inappropriately. Convert everyone over, including OMAP. As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot with this change. Mark this option as BROKEN and make it depend on BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.) reverted until such time it can be fixed correctly.
