My bad, I've incorrectly printed this as 0x%lu instead of %lx, the
following output is correct:

SMAP type=01 base=0000000000000000 len=0000000000092400
SMAP type=02 base=00000000000f0000 len=0000000000010000
SMAP type=01 base=0000000000100000 len=000000003ff6e000
SMAP type=04 base=00000000dfdf9c00 len=0000000000052000
SMAP type=03 base=00000000dfe4bc00 len=0000000000002000
SMAP type=02 base=00000000dfe4dc00 len=00000000001b2400
SMAP type=02 base=00000000f8000000 len=0000000005000000
SMAP type=02 base=00000000fe000000 len=0000000000d00400
SMAP type=02 base=00000000fee00000 len=0000000000100000
SMAP type=02 base=00000000ffb00000 len=0000000000500000
SMAP type=02 base=0000000100000000 len=00000000a0000000
(XEN) Trying to access 0x40000000 <- Printed from vioapic_range.

In this case 0x40000000 falls in range reported as usable RAM by Xen:

SMAP type=01 base=0000000000100000 len=000000003ff6e000

Which goes from

[0x100000, 0x4006e000]

Roger.
