Subject: [PATCH 2.6.21 review II] [10/10] VMI: Paravirt debug defaults off


From: Zachary Amsden <zach@...are.com>
Deliberate register clobber around performance critical inline code is great for
testing, bad to leave on by default.  Many people ship with DEBUG_KERNEL turned
on, so stop making DEBUG_PARAVIRT default on.
