Hi,
looking at it, can you try sticking (u32) at the end of line 212; that multiply is not very likely to exceed 32 bits
Nopeee.
data->predicted_us = DIV_ROUND_CLOSEST((u32)
data->expected_us * data->correction_factor[data->bucket],
(u32)RESOLUTION * DECAY);
It did properly rebuild drivers/cpuidle/governors/menu.o.
Still happening.
IOW it must be somewhere inside the DIV_ROUND_CLOSEST macro or so.
it looks like your GCC has a problem dividing by a power of two though;
both DECAY and RESOLUTION are powers of two...
