From f798634d806615bee27d1b83479034087a02aa0f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 16 Jul 2007 17:05:11 -0700 Subject: [PATCH] [SERIAL] SUNHV: Fix jerky console on LDOM guests. Mixing putchar() and write() hvcalls does not work %100 correctly. But we should be using write() all the time if we can, even from ->start_tx(), anyways. Signed-off-by: David S.
