[ARM] 5383/2: unwind: Add core support for ARM stack unwinding
This patch adds the main functionality for parsing the stack unwinding information generated by the ARM EABI toolchains. The unwinding information consists of an index with a pair of words per function and a table with unwinding instructions. For more information, see "Exception Handling ABI for the ARM Architecture" at: http://infocenter.arm.com/help/topic/com.arm.doc.subset.swdev.abi/index.html Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
