2012-01-13	ARM: Add arm_memblock_steal() to allocate memory away from the kernel	Russell King
	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.

2010-10-27	ARM: fix memblock breakage	Russell King
	Will says: \| Commit e63075a3 removed the explicit MEMBLOCK_REAL_LIMIT #define \| and introduced the requirement that arch code calls \| memblock_set_current_limit to ensure that the __va macro can \| be used on physical addresses returned from memblock_alloc. Unfortunately, ARM was missed out of this change. Fix this. Reported-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
