Subject: [Qemu-devel] [PATCH] x86: Filter out garbage from segment flags dump
Date: Mon, 27 Dec 2010 15:52:24 +0100	[thread overview]
Message-ID: <4D18A828.2040801@web.de> (raw)

From: Jan Kiszka <jan.kiszka@siemens.com>

Only bits 8..23 of the segment flags contain valid data, so only dump
those when printing the CPU state.
