[Xen-devel] [PATCH 2/2] linux/x86: Disable all accesses to the IO-APIC pages
Similar to the local APIC changes, the IO-APIC access mechanisms should also be restricted to the Xen-specific ones (other than for the local APIC, where the access mechanisms must be entirely suppressed). A nice side effect of this is that the fixmap area shrinks quite a bit, allowing 32-bits to use a little more low memory.
