Subject: [PATCH V4 06/14] powerpc/mm/slice: Update slice mask printing to use bitmap printing.
Date: Thu, 16 Mar 2017 16:07:05 +0530 [thread overview]
Message-ID: <1489660633-24125-7-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1489660633-24125-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
We now get output like below which is much better.
[ 0.935306] good_mask low_slice: 0-15
[ 0.935360] good_mask high_slice: 0-511
Compared to
[ 0.953414] good_mask:1111111111111111 - 1111111111111.........
I also fixed an error with slice_dbg printing.
