Thanks for the bug report and patch.  I have checked your patch in, 
along with the addition of an assert in arm_parse_cpu, which should 
catch problems like this in the future.

	* config/tc-arm.c (selected_cpu_name): Increase length of array to
	accomodate "Samsung Exynos M1".
	(arm_parse_cpu): Add assertion and length check to prevent
	overfilling selected_cpu_name.
