CVS commit: [bouyer-xen2] src/sys/arch/xen

[Manuel Bouyer <bouyer%netbsd.org@localhost>]

Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/arch/xen/i386 [bouyer-xen2]: pmap.c
        src/sys/arch/xen/include [bouyer-xen2]: pmap.h
        src/sys/arch/xen/x86 [bouyer-xen2]: bus_space.c

Log Message:
bus_space_map/unmap() should map machine addresses, not physical addresses,
for memory-mapped I/O. So use pmap_kenter_ma() instead of pmap_kenter_pa(),
and introduce pmap_extract_ma() to get the machine address of a mapping.
Now memory-mapped I/O should work outside of the ISA hole (note that PCI
devices are usually mapped in the ISA memory hole anyway).
