Subject: [RFC PATCH v2 02/25] x86: NUMA: Fix datatypes and attributes
Date: Tue, 28 Mar 2017 21:23:10 +0530	[thread overview]
Message-ID: <1490716413-19796-3-git-send-email-vijay.kilari@gmail.com> (raw)
In-Reply-To: <1490716413-19796-1-git-send-email-vijay.kilari@gmail.com>

From: Vijaya Kumar K <Vijaya.Kumar@cavium.com>

Change u{8,32,64} to uint{8,32,64}_t and bool_t to bool.
Fix attributes coding styles.
Also change memnodeshift to unsigned int.
