aarch64 is a different architecture than arm. Some compilers might choke when both __arm__ and __aarch64__ are defined. This change separates the checks for arm and for aarch64 in the isa_defs.h header files. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Windel Bouwman <windel@windel.nl> Closes #10335 Closes #13151
