Subject: [PATCH 03/12] mips: use {cpu|node}mask pr_cont and seq output functions
Date: Wed, 10 Dec 2014 10:52:45 -0500	[thread overview]
Message-ID: <1418226774-30215-4-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1418226774-30215-1-git-send-email-tj@kernel.org>

Convert the existing user of cpu{mask|list}_scnprintf() and
node{mask|list}_scnprintf() which use them just to printk or
seq_printf() the resulting buffer to use the following functions
instead respectively.

* For printk: cpu{mask|list}_pr_cont() and node{mask|list}_pr_cont().

* For seq_file: seq_cpumask[_list]() and seq_nodemask[_list]().

Because these conversions usually break up a single output function
call into multiple, the reduction is LOC isn't too big but it removes
unnecessary complexity and/or arbitrary limit on the length printed.

This patch is dependent on the previous patch ("bitmap, cpumask,
nodemask: implement pr_cont variants of formatting functions") which
is planned to go through -mm.  It'd be the easiest to route this
together.  If this should go through the subsystem tree, please wait
till the forementioned patch is merged to mainline.
