Hi,
Looks like this is coming from the use of mult_frac() if I am reading the
generated .s file correctly:
# ../drivers/soc/qcom/qcom_stats.c:224: entry[i].dur = mult_frac(MSEC_PER_SEC, entry[i].dur, ARCH_TIMER_FREQ);
mulhwu 3,22,4 # tmp194, tmp190, MEM[(long long unsigned int *)_107 + 16B]
mulli 9,9,1000 # tmp185, MEM[(long long unsigned int *)_107 + 16B],
mulli 4,4,1000 # tmp3, MEM[(long long unsigned int *)_107 + 16B],
add 3,9,3 #, tmp185, tmp194
bl __udivdi3 #
