The patch titled
Subject: cpuidle: menu: use DIV_ROUND_CLOSEST_ULL()
has been removed from the -mm tree. Its filename was
cpuidle-menu-use-div_round_closest_ull.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Javi Merino <javi.merino@xxxxxxx>
Subject: cpuidle: menu: use DIV_ROUND_CLOSEST_ULL()
Now that the kernel provides DIV_ROUND_CLOSEST_ULL(), drop the internal
implementation and use the kernel one.
