Subject: [PATCH 5/5] just realized that it's broken
Date: Fri, 30 Jan 2009 10:48:04 +0000 [thread overview]
Message-ID: <4982E8F4.76E4.0078.0@novell.com> (raw)
This patch was moving the cpumask out of struct page_info into the page
itself, but I just realized that this it not valid, since the purpose of the mask
is to avoid a later TLB flush, hence the base assumption is that the page
might still be in the TLB of some CPU, thus making it possible for a mis-
behaved guest to still write to that page.
Sorry for the mis-numbering,
Jan
