On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores always run at the same CCLK. In addition, the current implementation has flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the global kernel loops_per_jiffy and not the per_cpu one. So punt all of the per-cpu handling and go back to the global shared one. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
