Not anymore :)
Since commit c4c9a040ecb7 ("clocksource: import ARC timer driver"),
see
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c4c9a040ecb7297e011e579f5a9cc280e42d725f
we have this:
---------------------->8----------------------
config ISA_ARCV2
bool "ARC ISA v2"
select ARC_TIMERS_64BIT
---------------------->8----------------------
which really means if one selects ISA_ARCV2 then ARC_TIMERS_64BIT gets selected
automatically
and there's no way to override it from either menuconfig or defconfig.
Probably behavior that you meant was to keep a separate "config
ARC_TIMERS_64BIT"
and have it "default y if ISA_ARCV2".
