The patch titled
Alpha: increase PERCPU_ENOUGH_ROOM
has been removed from the -mm tree. Its filename was
alpha-increase-percpu_enough_room.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Alpha: increase PERCPU_ENOUGH_ROOM
From: "Aneesh Kumar K.V" <aneesh.kumar@xxxxxxxxx>
Module loading on Alpha was failing with error "Could not allocate 8 bytes
percpu data".
Looking at dmesg we have the below error "No per-cpu room for modules."
Increase the PERCPU_ENOUGH_ROOM in a similar way as x86_64
