From 83d9f65bdae6f6b34d75282c6618d3f50846849a Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 29 Aug 2010 18:12:24 -0700 Subject: x86, setup: Fix earlyprintk=serial,ttyS0,115200 Torsten reported that there is garbage output, after commit 8fee13a48e4879fba57725f6d9513df4bfa8e9f3 (x86, setup: enable early console output from the decompressor) It turns out we missed the offset for that case.
