Hi,

The attached patch fixes a bug in the AArch64 __clear_cache
implementation in which the loop iterating through the cache lines to
clear started from the first address to clear, incrementing by the size
of the cache line, and potentially missing to clear the last cache line.

Patch passes the regression test on aarch64-none-gnu-linux.  OK for
trunk and aarch64-4.7-branch?

Thanks,
Yufeng

	* config/aarch64/sync-cache.c (__aarch64_sync_cache_range): Align
	the loop start address for cache clearing.

OK
