Subject: [PATCH 02/22] mini-os: make dump_regs() work in early boot
Date: Tue, 23 Aug 2016 17:15:48 +0200 [thread overview]
Message-ID: <1471965368-6159-3-git-send-email-jgross@suse.com> (raw)
In-Reply-To: <1471965368-6159-1-git-send-email-jgross@suse.com>
dump_regs() will result in page fault in early boot as there is no
current thread pointer. Handle this case.
