The /systemtap.stress/conversions.exp test fails on ia64. the tests works for
0xffffffff. Below is the related part of the systemtap.log:

done exp conversions.stp 0xffffffffffffffff 6
FAIL: conversions.stp 0xffffffffffffffff (6)
done conversions.stp 0xffffffffffffffff 6

The test above seems to be missing the failures for:

ERROR: kernel string copy fault
ERROR: kernel char copy fault

Page 149 of the "ia64 linux kernel", figure 4.11 shows that address mapping,
0xffffffffffffffff is a valid byte address. Might need to reconsider how this
tests picks the addresses.
