From 9a5963eb494c8a7be65199e15854551df7d2d939 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Wed, 16 Sep 2009 21:56:49 +0200 Subject: [PATCH] oprofile: fix oprofile regression: select RING_BUFFER_ALLOW_SWAP commit 85bac32c4a52c592b857f2c360cc5ec93a097d70 ring-buffer: only enable ring_buffer_swap_cpu when needed broke oprofile (at least on s390, but likely on all platforms). this patch lets oprofile select RING_BUFER_ALLOW_SWAP to make ring_buffer_swap_cpu usable for oprofile.
