[PATCH] Alpha: increase PERCPU_ENOUGH_ROOM
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 Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@gmail.com> Cc: <Jay.Estabrook@hp.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
