The patch titled
drivers/net/xen-netfront.c: Use DIV_ROUND_UP
has been removed from the -mm tree. Its filename was
drivers-net-xen-netfrontc-use-div_round_up.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: drivers/net/xen-netfront.c: Use DIV_ROUND_UP
From: Julia Lawall <julia@xxxxxxx>
The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /
(d)) but is perhaps more readable.
An extract of the semantic patch that makes this change is as follows:
