Subject: [PATCH 2/4] ia64: remove unused num_dma_physpages member from 'struct early_node_data'
Date: Mon, 23 Jul 2018 08:56:56 +0300	[thread overview]
Message-ID: <1532325418-22617-3-git-send-email-rppt@linux.vnet.ibm.com> (raw)
In-Reply-To: <1532325418-22617-1-git-send-email-rppt@linux.vnet.ibm.com>

Since commit 05e0caad3b7b ("[PATCH] Have ia64 use add_active_range() and
free_area_init_nodes") the num_dma_physpages member of 'struct
early_node_data' is calculated but never used. Remove it.
