List-id: Discussion of the ia64 port of Xen <xen-ia64-devel.lists.xensource.com>

per vcpu vhpt
implement per vcpu vhpt option. allocate VHPT per vcpu.
added compile time option, xen_ia64_pervcpu_vhpt=y, to enable it.
Its default is on.
added xen boot time option, pervcpu_vhpt=0, to disable it.

This patch focuses on vcpu migration between physical cpus
becaseu vcpu is heavily migrated with credit scheduler.
This patch tries to reduce vTLB flush when vcpu is migrated
