The patch titled
i386: account for module percpu space separately from kernel percpu
has been removed from the -mm tree. Its filename was
i386-account-for-module-percpu-space-separately-from-kernel.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: i386: account for module percpu space separately from kernel percpu
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
Rather than using a single constant PERCPU_ENOUGH_ROOM, compute it as the
sum of kernel_percpu + PERCPU_MODULE_RESERVE. This is taken directly from
the x86_64 tree.
