From ad32e8cb86e7894aac51c8963eaa9f36bb8a4e14 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 10 Nov 2009 19:46:19 +0900 Subject: swiotlb: Defer swiotlb init printing, export swiotlb_print_info() This enables us to avoid printing swiotlb memory info when we initialize swiotlb. After swiotlb initialization, we could find that we don't need swiotlb. This patch removes the code to print swiotlb memory info in swiotlb_init() and exports the function to do that.
