Subject: [RFC][PATCH 1/3][v2] perf: Move PERF_MEM*SHIFT macros up the block
Date: Wed, 26 Jun 2013 00:41:06 -0700 [thread overview]
Message-ID: <20130626074106.GA3741@us.ibm.com> (raw)
From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>
Date: Fri, 21 Jun 2013 14:03:01 -0700
Subject: [RFC][PATCH 1/3][v2] perf: Move PERF_MEM*SHIFT macros up the block
Values for the PERF_MEM_*SHIFT macros depend on the block before
them, so it would be more readable if they are in the beginning
of the block.
