[PATCH 0/3] GDT virtualization performance
Three patches to clean up GDT access in Linux to make it friendly to
virtualization environments. The basic problem is that the GDT must
be write protected, which causes spurious overhead when the GDT lies
on the same page as other data. This problem exists both for VMware
and Xen; Xen actually requires page isolation, so we have implemented
the most general and compatible solution.
