[Xen-devel] [PATCH 5/5] just realized that it's broken

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

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
