Hi Fu,

All error/warnings (new ones prefixed by >>):
drivers/clocksource/arm_arch_timer.c:70:13: error: variable 'arch_timer_uses_ppi' has initializer but incomplete type
static enum ppi_nr arch_timer_uses_ppi = VIRT_PPI;
I have figured out this, I should move a change from patch 4/15 to here to avoid the problem.
it should be static enum arch_timer_ppi_nr arch_timer_uses_ppi = VIRT_PPI; will improve this
Thanks
