Subject: [PATCH][8/9] Really enable gdbserver for real mode code.
Date: Mon, 25 Jul 2005 14:01:50 -0700 [thread overview]
Message-ID: <20050725210150.GA24420@intel.com> (raw)
Really enable gdbserver for real mode code.
Missed out one instance where we need to check if we're running on
1:1 page tables with guest paging disabled.
