src/sys/arch/xen/x86: x86_xpmap.c xen_bus_dma.c xenfunc.c
Starting with Xen 3 API, MMU_EXTENDED_COMMAND (tlb flush, cache flush, page
pinning/unpinning, set_ldt, invlpg) operations cannot be queued in the
xpq_queue any more, as they use their own specific hypercall, mmuext_op().
Their associated xpq_queue_*() functions already call xpq_flush_queue()
before issuing the mmuext_op() hypercall, which makes these xpq_flush_queue()
calls not necessary.
Rapidly discussed with bouyer@ in private mail. XEN3_DOM0/XEN3PAE_DOM0 tested
through a build.sh release, amd64 was only compile tested. No regression
