CVS commit: src/sys/arch

Module Name:    src
Committed By:   jym
Date:           Fri Feb 12 01:55:46 UTC 2010

Modified Files:
        src/sys/arch/x86/x86: pmap.c
        src/sys/arch/xen/x86: x86_xpmap.c xen_bus_dma.c xenfunc.c

Log Message:
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 release, amd64 was only compile tested. No regression
